Key Features

Key Features
The Conext SW Inverter/Charger is a true sine wave inverter/charger that can be
used for off-grid, backup, solar, and hybrid applications. The Conext SW Inverter/
Chargers are designed to operate with a wide variety of generators and are
capable of operating in parallel with a generator for short durations to assist with
starting large loads. The Conext SW is a convenient combination of an inverter,
multi-stage battery charger, and transfer switch in one electronic device.

The Conext SW Inverter/Charger’s key features are:

• True Sine Wave output - as an inverter, the Conext SW provides true sine wave
power for your microwave, entertainment system, computer, and other loads.
This power is identical to the AC source provided from the utility grid (power
company).
Some of the benefits of high efficiency true sine wave power include consistent
cooking in your microwave, handling of sensitive loads such as your TV set,
dimmer switches, and appliances with speed controls.
• Multiple unit configuration - the Conext SW Inverter/Charger has a highly
versatile platform capable of parallel multiple unit configuration1 to increase
power levels.
• High surge capacity - the Conext SW Inverter/Charger has a surge rating that is
twice the maximum continuous output power rating to start difficult loads like well
pumps, refrigerators, or A/C compressors. See “Inverter Specifications” on
page 6–2.
• Power factor correction - Power factor-corrected (PFC) input minimizes AC
input current required for charging, increasing AC pass-through capacity.
• Multi-stage charging - the Conext SW Inverter/Charger has a high output, multi-
stage charging capability that minimizes charging time.
• Adjustable frequency - the Conext SW Inverter/Charger is capable of operating
from a 50Hz and 60Hz power source by extending the AC qualification frequency
range. See “AC Settings” on page 4–20.
• Temperature-controlled, variable-speed internal cooling fans - the fans turn
on when the internal temperature reaches 45 °C and reaches maximum speed at
70 °C. The fan turns off when the internal temperature falls to 40 °C.
• Xanbus-enabled - the Conext SW Inverter/Charger is also Xanbus-enabled
which allows network compatibility and communication with other Xanbus-
enabled devices. See more information under “Xanbus System” on page 2–2.

1.In Conext SW Inverter/Chargers, multiple unit configuration (installation) is limited to two units -
one master unit and one slave unit.

Introduction

Key Features Explained

Built-in Charge For the unit to perform at the highest level, the batteries must be charged
Formulas correctly. The Conext SW has optimized algorithms for flooded, gel, and AGM
batteries.

Battery Since battery temperature is a key factor in correct charging, the charging
Temperature formula must be adjusted (automatically and in real time) according to the actual
Sensor battery temperature to ensure that batteries are fully charged, but not
overcharged. For this reason, a battery temperature sensor (BTS) is included
with the Conext SW that works with a temperature-compensated charge formula.

Manual Over a period of time, the cells in a flooded battery can develop uneven
Equalization chemical states. This can result in a weak (undercharged) cell which, in turn, can
reduce the overall capacity of the battery. To improve the life and performance of
a non-sealed, flooded battery, the Conext SW’s multi-stage charging cycle
includes a manual equalize mode that can be used, if recommended by the
battery manufacturer.

Dead Battery Another feature that the Conext SW includes is dead battery charging. The
Charging Conext SW—unlike many chargers—has the ability to recharge batteries even if
the battery voltage is very low, that is, as low as 12 volts.

Load Management The Conext SW has a built-in transfer relay that connects your inverter output or
AC input from the AC generator to your loads. Because the usual AC power
sources such as small generators often have limited current availability, having
the capability to manage your AC loads is extremely valuable. The Conext SW
provides a number of features to facilitate this.

• The charger is power factor corrected to use AC current as efficiently as

possible. Minimizing the AC current used by the charger means more
current is available for your AC loads.
• The Conext SW has a power share feature which prioritizes your AC
loads by reducing the charge current and maintaining the total input
current to less than the breaker setting.

Occasionally, AC input sources have low voltage. To avoid loading these weak
sources any further, the charger automatically reduces its AC current draw as the
AC voltage approaches the minimum acceptable level.

Key Features

Multiple Unit Configuration

Conext SW Inverter/Charger supports multiple unit configuration to increase
capacity. This also requires the installer to select a Master unit and a Slave unit or
units.

Parallel Multiple Multiple unit configuration allows two inverter/chargers to operate in parallel
Unit Configuration thereby doubling the capacity in inverter mode. The multiple inverters
communicate over the Xanbus network and intelligently share the load and
balance the load between the units. The Master Conext SW synchronizes
operation, through the Xanbus network, between the other unit. When AC loads
are present, all units produce power, effectively sharing the load. When Search
mode is enabled, only the Master unit produces the AC output.

Multiple Unit Multiple Conext SW Inverter/Chargers synchronize charging stages to ensure

Charging efficient charging of the battery bank. When a single unit transitions from bulk to
absorption so do all other units. In absorption, all units must complete the
absorption stage before transitioning to the next stage. Note that units do not
load share when charging except during the bulk stage. The Conext SWs stop
sharing charge current just before completing the bulk stage. The units do not
share charge current during the absorption and float stages.

Each unit charges batteries based on the Max Charge Rate setting and active
internal (temperature-based) deratings.

If equalization is enabled on one or more devices capable of equalization

charging, only those devices perform an equalize cycle after absorption. Other
devices transition to float (if three-stage charging is selected) or transition to AC
pass-through (if two-stage charging is selected).

Generator Support
The Conext SW inverter/chargers can operate in tandem with an AC generator to
temporarily assist power loads with large start-up demands such as air
conditioners and water pumps. An Automatic Generator Start device (AGS) must
be installed in the system in order for this feature to work.

When this mode is enabled and generator capacity defined, the inverter will
come on-line and assist the generator when the generator reaches its capacity.
The battery bank must be well charged in order for the inverter to engage this
mode. For more details, see “Gen Support Settings” on page 4–22.

Introduction

Basic Protection Features

The Conext SW has the following protection features:

• Over temperature shutdown for critical components such as the transformer

and the power board
• Battery temperature sensor (BTS) failure/battery temperature out-of-range
fault protection
• DC output over voltage protection during charge mode
• AC output overload and short circuit protection during invert mode
• AC backfeed1 protection

The Battery Temperature Sensor (BTS) provides these protection features:

• Battery over temperature charging protection preventing battery charging at

60 °C or higher
• Charging voltage compensation based on the temperature of the battery the
BTS is connected to

1.An AC backfeed error occurs when the AC output of the inverter/charger is connected or
routed back to the inverter/charger’s AC input terminal or if the an AC internal transfer relay error
is detected.

Components and Mechanical Features

System Components
The Conext SW uses Xanbus, a network communications protocol developed to
send Conext SW’s operational settings and status to other Xanbus-enabled
devices. You can configure and monitor the Conext SW and every Xanbus-
enabled device in the system using an optional System Control Panel (SCP).

Another component is the optional Automatic Generator Start (AGS) which allows
operation with a wide range of generators, supported through a dedicated
generator input. Simply, the AGS automatically starts and stops your generator.

Solar charge controllers allow renewable energy collected from the sun to charge
batteries as might be the case in an off-grid application of Conext SW. The
charge controllers form part of the Xanbus network.

See “Xanbus-enabled Products and Other Accessories” on page 2–3 for part
numbers.

Xanbus System
The Xanbus system includes the Conext SW and other Xanbus-enabled devices.
The Conext SW is the device in a Xanbus system that typically provides network
power—500 mA at 12 VDC. All of the Xanbus-enabled devices, such as the
Conext SW, the SCP, and the AGS are able to communicate their settings and
activity to each other.

chapter.
• Start Up Behavior
• Conext SW Front Panel
• Conext SW with the SCP – System Control Panel
• Battery Charging Reference

975-0636-01-01 Rev B 3–1

ConextSWEUROwnersGuide.book Page 2 Wednesday, December 5, 2012 10:33 AM

Operation

Start Up Behavior
When the Conext SW is powered up (energized) or has been reset (using the
Reset button on the front panel), all of the front panel LEDs illuminate and remain
on for a minimum of five seconds. During this interval, the fans also turn on as the
unit executes internal diagnostics.

The Conext SW inverter function is initially disabled (meaning the unit will not
invert even if there is sufficient battery voltage) every time the Conext SW is
energized for the first time. After being energized, the Inv Enable button on the
front panel can be used to enable or disable the inverter. A separate control
device called a System Control Panel (or SCP) may also be used to enable or
disable the inverter. However, the unit will remember its inverter function setting in
succeeding operations. This means that if the inverter function is left enabled
before a reset or power down-power up cycle, the inverter function will remain
enabled.

When a function is enabled, it generally means that it is “standing by” and other
conditions may have to be met before the function is utilized. For example, the
charger function on the Conext SW may be enabled, but it will not charge unless
qualified AC power is present. Similarly, even if the inverter function is enabled,
inverting may not occur if the batteries cannot supply the energy required for the
loads.

IMPORTANT: Review the “Important Safety Instructions” on page v before

operating the inverter/charger.

Inverter Operation Using the Front Panel

Inverter Operation Using the Front Panel

IMPORTANT: Review the “Important Safety Instructions” on page v before
operating the inverter/charger.
Once the inverter/charger is installed, you can operate it in invert mode. The
steps below will test the unit for normal operation using the front panel.

To test the inverter using the front panel:

1. Press the Inv Enable button on the Conext SW on the front panel. The
Inv Enabled LED illuminates.
2. Turn on the main AC breaker or AC disconnect to supply AC input power to
the inverter.

NOTE: The Inv Enabled LED will remain lit. However, AC will continue to be
passed through (also called AC bypass) to the loads until conditions exist that
cause AC to be disqualified, in which case the unit will start inverting. The AC
IN LED should also illuminate. The Charging LED will start flashing to
indicate that the unit is charging the battery. The charger automatically starts
when qualified AC power is connected and when the battery is not fully
charged.

3. Turn off the main AC breaker or AC disconnect to stop AC input power from
going into the inverter.
4. Place a load on the inverter. This also usually means turning on the inverter’s
AC distribution sub-panel’s breaker switch.
5. Connect a load such as a lamp into an outlet connected to the sub-panel
circuit and turn it on. The lamp lights up.
6. Repeat step #2. The lamp will remain lit up.
7. Repeat step #3. The inverter/charger should invert immediately. The transfer
relay will make a clicking sound and the Inv Enabled LED will illuminate.
The lamp should remain lit up. If any part of this test does not happen
correctly, determine the cause before continuing to use the unit.
8. Monitor the Conext SW front panel.
The indicator LEDs on the front panel show you the operating status of the
Conext SW. A description of the LEDs is provided in Table 3-1.
If none of the front panel LEDs are on, see “General Troubleshooting
Guidelines” on page 5–2.

Inverter Operation Using the Front Panel

Operating Limits for Inverter Operation

Temperature The Conext SW series of inverter/chargers will operate at rated
power continuously at 25 °C with some models capable of continuous operation
at much higher ambient temperature. However, the continuous power rating at
elevated ambient temperature may differ between models. See “Environmental
Specifications” on page 6–4 for full details. In higher ambient temperatures, if the
loads draw full power for an extended period of time, the unit may shut down to
protect itself against overheating.

Surge Power The Conext SW series of inverter chargers feature a surge rating
of 200% of rated power for five seconds at 25 °C. See “Inverter Specifications”
on page 6–2 for full details. Operating the inverter/charger in conditions outside
of normal rated power and temperature limits, however, will result in thermal
shutdown and/or significantly decreased performance. See “Inverter
Specifications” on page 6–2 for information on continuous operation at higher
than rated power.

Difficulty on starting loads The inverter/charger should be able to operate all

AC loads rated at or below its power rating. Some high horsepower induction
motors used in pumps and other motor-operated equipment require very high
surge currents to start, and the inverter/charger may have difficulty starting these
loads.

If you have problems starting certain loads, ensure that:

• The battery connections are tight and clean.

• The DC cabling is no longer than the recommended length. Refer to the
Conext SW Inverter/Charger Installation Guide for this information.
• The AC wiring is of recommended size. Refer to the Conext SW Inverter/
Charger Installation Guide for this information.
• The battery is of sufficient capacity and is fully charged.

Battery power during AC bypass When qualified incoming AC is detected by

the inverter/charger and the battery is sufficiently charged, the AC is
automatically passed through to the loads. However, when there is qualified
incoming AC but there is no battery power (that is, the battery is disconnected
from the inverter/charger for some reason), the inverter/charger will not be able to
successfully pass the AC through to the loads. A connected battery with
sufficient power is needed for AC bypass to occur.

NOTICE
EQUIPMENT DAMAGE
Do not energize and operate the inverter/charger with an AC source before a
DC source like the battery. Do not rely solely on AC bypass power to provide
energy to connected loads. Always operate with a battery connected to the
inverter/charger.
Failure to follow these instructions can damage the inverter/charger.

Operation

Operating Limits for Charger Operation

By default, the maximum charger output current is the rated charger output
current for the particular model. Using the SCP, you can reduce the total output if
you change the maximum charge rate (Max Chg Rate) on the Conext SW Basic
Settings menu or Inverter Settings menu under Advanced Settings.

The charger can charge batteries when the AC input voltage is within the
minimum and maximum range of 170 to 270 VAC. They are the default minimum
and maximum settings. The minimum range setting can be adjusted from 170 to
220 VAC and the maximum range setting from 240 to 270 VAC. The charger can
also be configured to accept and operate from a wide AC source frequency of
between 40 to 70 Hz. The default range setting is between 45 to 55 Hz. This wide
range allows the Conext SW to charge your batteries even when incoming AC
voltage becomes less than the typical 50 Hz.

Power Share The Conext SW charger uses AC INPUT L to charge the batteries.
The AC loads have priority, which means that the charger will reduce its output
with large AC loads and increase the output again when the AC load decreases.
The regulatory maximum for continuous AC loads is 80% of the breaker rating
that the loads are connected to.

The Conext SW senses pass-through current going to the AC load. The

difference between the pass-through (load) and 80% of the Power Share setting
is the current that is available for charging the batteries.

For example, if the AC input of the Conext SW is from an AC panel with a 30-amp
breaker, the Power Share setting on the SCP should be selected as 30-amp.
Based on this, the charger will control the charge current so that the total current
draw is equal to or less than 24 amps in this case. Should the load current be
more than about 24 amps, the charger output will reduce to zero (0) amp, but the
Conext SW will continue to supply power to the loads. The Conext SW will
continue to pass-through power to the loads, even if the load current exceeds the
Power Share setting. In this case, it will be up to the user to remove/disconnect
loads if tripping the AC input breaker supplying the Conext SW is to be avoided.

Inverter/Charger Operation using the System Control Panel (SCP)

Using the Standby Button

The Standby button has two functions, depending on how it is pressed. First,
when only the Standby button is pressed, it can disable inverting and charging
for all Conext SW units in the system. Second, when it is pressed simultaneously
with the Exit button, this action puts the entire system into Standby mode.

Pressing the Standby button produces the same result as disabling “Invert” and
“AC Charge” from the System Settings menu on the SCP. Pressing the Standby
button momentarily affects only Conext SW units; it does not affect charge
controller operation. After disabling inverting and charging with the Standby
button, the system continues to pass AC input through to the loads.

Pressing the Exit and Standby buttons at the same time puts the entire Xanbus
network system (including charge controllers) into Standby mode. In Standby
mode, the Conext SW stops passing AC input through to the loads.

After the keypress command to enter Standby mode, the AGS – Automatic
Generator Start (if installed) shuts down the generator (if it is running) after a
cool-down cycle.

SCP Navigation
This section describes the different types of screens and menus on the SCP. To
monitor Conext SW operation and change settings, it is helpful to know how to
locate these screens and menus.

Pressing the down arrow button from the Conext SW Home screen displays the
Home screens for other Conext SW units and other Xanbus-enabled devices in
the system.

Table 3-2 Conext SW Home Screen States

Conext SW
Status Displayed When...
Invert The Conext SW is supplying power to loads by inverting power
from the batteries. AC input from the AC generator or grid is
absent or out of nominal range.
Qualifying The Conext SW is determining if AC input from the AC
AC generator or grid is within a usable voltage and frequency
range. It is also displayed when the Conext SW is awaiting
application of AC power or a command to enable invert mode.
GenSupport There is AC input from the generator, and the Conext SW is
supporting the generator by supplying additional power to the
critical loads.

The Conext SW supports the generator when the AC load

current drawn exceeds the GenSup Amps setting for 1 to 2
seconds.

The Conext SW uses stored DC capacity to load share with the

generator until the total AC load current (generator plus
inverter output) drops by 2 amps plus 10 per cent of the
GenSup Amps setting for 6 seconds.

For example, if GenSup Amps is set to 10 amps, the inverter

starts to support when the load exceeds 10 amps for 2
seconds and stops when it drops more than 3 amps below the
GenSup Amps setting, or 7 amps (2 amps plus 10 per cent of
10 amps = 3 amps).

The system can enter this state if the battery voltage is above
the Low Batt Cut Out setting and Gen Support is enabled. See
“Gen Support Settings” on page 4–22.
Bulk The Conext SW is bulk-charging the batteries from qualified
AC input from an AC generator or grid. AC input is also passed
through to the load while bulk-charging.
Absorption The Conext SW is absorption-charging the batteries from
qualified AC input from an AC generator or grid. AC input is
also passed through to the load while absorption-charging.
ABS Finish The Conext SW has completed the absorption stage and is
waiting for other Conext SWs in the system to complete
absorption. This status can occur only when there is another
Conext SW also charging the battery.
Equalize Equalization has been turned on, and the Conext SW is
equalizing the batteries after completing a full charge cycle.

Item Description
Hi Batt Cut Out Hi Batt Cut Out sets the maximum battery voltage at which
the inverter will operate. If the battery voltage exceeds this
limit for more than one minute, the Conext SW displays a
fault message and shuts down. The inverter will not support
AC loads when in this condition. If a qualified AC source is
present, the unit passes AC through to the loads. The
inverter automatically restarts when the voltage drops to
3 volts below the Hi Batt Cut Out setting. If battery
voltage continues to rise after shutdown, an external
charger may still be charging the batteries. The Conext SW
cannot control how external chargers operate.
Search Watts Search Watts sets the Conext SW’s search sensitivity when
search mode is enabled. When a load larger than this
setting is present, the inverter starts producing AC output.
Enabling search mode from the Setup menu can minimize
power draw from the battery during periods of low demand
from loads. Also see “Using Search Mode” on page 4–11.
Search Delay Search Delay sets the time between search pulses. When
searching for loads, the Conext SW sends out search
pulses to determine if a load is present. If the Conext SW
finds a load above the Search Watts setting, the inverter
turns on. Conext SW power draw while in search mode
decreases when Search Delay is increased, but the Conext
SW’s response time to active loads is slower.

Using the Low Battery Cut Out and LBCO Delay Settings
The Low Batt Cut Out setting is the lowest battery voltage level acceptable for
use by the inverter. When the batteries discharge to the Low Batt Cut Out setting
and are held at or below this level for the LBCO Delay time, the inverter output
shuts down and transfers any available AC source (like an AC generator) to the
charger to bring the battery level back above the Low Batt Cut Out setting. After
shutdown, the inverter does not support any AC loads, and AC loads must be
powered by an AC generator.

If using an automatic generator starting system, it is recommended to set the

Xanbus AGS voltage trigger setting higher than the Conext SW Low Batt Cut Out
voltage. Otherwise, inverter output turns off before the generator automatically
starts, causing the battery voltage to recover slightly. This may then stop the
Xanbus AGS from starting the generator or result in the inverter cycling on and off
multiple times before the generator automatically starts.

If using an automatic generator starting system with the start trigger set to the
same voltage as the LBCO voltage, do not set the LBCO Delay for less than the
amount of time it takes the generator to start and connect. Otherwise, inverter
output turns off before the generator automatically starts, causing the battery
voltage to recover slightly. This may then stop the Xanbus AGS from starting the
generator or result in the inverter cycling on and off multiple times before the
generator automatically starts.

Using Search Mode

Why use Search Search mode allows the inverter to selectively power only items that draw more
mode? than a certain amount of power, which can result in power savings.

The Conext SW has a no-load power draw of about 38 W (SW 2524 230) and
40 W (SW 4024 230). Enabling Search mode reduces this power draw to less
than 8 W for all models.

Search mode operates differently in single-unit and multiple unit installations.

Single units When a single Conext SW has Search mode enabled, the inverter sends
electrical search pulses through its AC output. These search pulses search for
connected AC loads. The delay between search pulses is set using the Search
Delay setting.

After a load larger than the Search Watts setting is detected, the inverter
turns on.

Multiple units To use Search mode in multiple unit installations with two paralleled Conext SW
units, the master unit must have Search mode disabled. The slave unit must have
Search mode enabled.

When Search mode is disabled on the master unit and Search mode is enabled
on the slave unit, only the master Conext SW operates, and the slave unit comes
online only when the load exceeds approximately 60% of the rated output of the
master unit. When the load drops below 20% of the master’s rated output, the
slave unit turns off.

ConextSWEUROwnersGuide.book Page 12 Wednesday, December 5, 2012 10:33 AM

Configuration via SCP

When to set up The Search mode feature is only valuable if the inverter can spend a couple of
Search mode hours “sleeping” each day. Therefore, if Search mode is to be used it must be
adjusted properly. The initial adjustment should be made so that the inverter
comes on only when needed.

Certain types of loads can cause Search mode not to work as expected. These
types of loads are described on “Problem Loads” on page 5–3 of the
Troubleshooting chapter. If these kinds of loads are in the system, follow the
suggestions given to eliminate the problem. If the problem loads cannot be
eliminated, there are two work-around solutions:

1. Disable Search Mode from the main Conext SW Setup menu, causing the
inverter to always remain at full output voltage.
2. Use a search-friendly companion load whose only purpose is to be switched
on to wake up the inverter to power the load that is unable to bring the
inverter out of Search mode.

NOTES:

• Search mode, by function, cannot work with clocks and timers or devices
that need power 24 hours a day. Examples of devices with timers include
video recorders, coffee makers with brew timers, refrigerators, and freezers
with defrost timers. Examples of devices that need power 24 hours a day
include telephone answering machines, alarm systems, motion detection
lights, and some thermostats.
• When the inverter is searching the output for loads, lights that have a
wattage lower than this setting may flash momentarily.

Using Inverter Block

The Inverter Block feature halts inverter function for a period of time each day.
This period of time is defined by the Inv Block Start and Inv Block Stop
settings. Inverter Block allows you to control which time period is not ideal for
inverting. This can be a time period when conserving battery power is more
important than running loads.

The Inverter setting must be initially Enabled in order for the Inverter Block to
work as intended. The Inv Block Start setting disables inverter function if the
inverter is initially enabled and then Inv Block Stop enables the inverter
function. However, if the Inverter setting is initially Disabled when Inv Block
Start commences, then the succeeding Inv Block Stop will not enable inverter
function automatically. The inverter will remain disabled.

Setting the Inv Block Start and Inv Block Stop to the same time disables
Inverter Block. Disabling Inverter Block means that inverting is allowed to occur
at any time when the right conditions for inverting exist.

NOTE: In a multiple unit configuration, set the same Inverter Block settings to
both the master and slave units.

Battery Charger Functions

When AC power is available, the Conext SW can operate as a battery charger.
Different battery types and chemistries require different charging voltage levels.
Not charging batteries at the required levels can shorten battery life or damage
the batteries. The Conext SW is configured at the factory to work with the battery
types recommended for inverter applications. If the default settings do not work
for your specific installation, you can adjust the charge stage settings (as
recommended by the battery manufacturer) on the Custom (Battery) Settings
menu (see page 4–18).

IMPORTANT: This information is provided for guidance only. Variations in

battery chemistry and site-specific environmental considerations mean that you
should consult your system designer or battery manufacturer for specific
recommendations for appropriate battery voltage and current settings.

Multi-Stage Charging Process

The charging cycle is a multi-stage process. Whenever qualified AC power is
present at the inverter’s input, it passes power through to the connected load and
begins charging the batteries.

NOTE: If the AC input fails or drops below the lower VAC limit (as set in AC
Settings), the complete multi-stage charge cycle (Bulk, Absorption, Float/No
Float) restarts once the source AC returns to within tolerance condition. If the
batteries are already nearly full, the charge cycle will take little time to complete.

Bulk Stage Bulk charge is the first stage in the charging process and provides the batteries
with a controlled, constant current. Once the battery voltage rises to the bulk
voltage threshold, the charger switches to the Absorption stage.

Absorption Stage Absorption charge is the second stage of battery charging and provides the
batteries with a controlled, constant voltage. During this stage, the current drawn
by the batteries slowly decreases. When this current falls below 2% of the battery
capacity, or when the configurable Absorb Time expires, the charger switches to
the Float or NoFloat stage, depending on the selected charge cycle.

NOTE: If there are DC loads on the batteries, the charger’s current may never
decrease to a level to initiate the next stage of charging. In this case, the
charger would stay in absorption until the Absorb Time setting is reached.

To make sure the charger does not remain in absorption for too long, adjust
Absorb Time on the Charger Settings menu. The timer begins at the start of the
absorption stage and terminates absorption charging if the charge current does
not decrease to below 2% of the battery capacity before the Absorb Time
setting expires. The Absorb Time setting may be increased if the charge cycle
continually runs the full Absorb Time in the absence of DC loads. This is an
indication of too large a battery bank for the selected Absorb Time setting.

ConextSWEUROwnersGuide.book Page 16 Wednesday, December 5, 2012 10:33 AM

Configuration via SCP

Float Stage Float charge maintains a trickle charge on the batteries whenever AC is present
on the Conext SW input. Float charging reduces battery gassing, minimizes
watering requirements (for flooded batteries), and makes sure the batteries are in
a constant state of readiness. When three-stage charging is selected, the
charger automatically switches to the float stage after the batteries have received
a bulk and absorption charge. The batteries will be maintained at the default float
voltage level for the selected battery type or the voltage selected under Float
Voltage on the custom battery Settings menu.

NOTE: The battery voltage can increase above the float voltage when using an
external charging device such as PV arrays, wind turbines, or micro-hydro
generators. Be sure to include appropriate charge management equipment
with all external DC sources.

Two-Stage Two-stage (bulk and absorption only, no float) mode differs from an ordinary
three-stage charge mode in that it does not continuously maintain the battery at
float voltage. Instead, the Conext SW begins charging the battery in bulk mode
whenever the battery voltage drops below the recharge level. While the battery
voltage is above the recharge level, the inverter continues to pass power through
from the AC source to the loads but does not actively charge the batteries.

Equalize-Charging the Batteries

Many battery manufacturers recommend periodic equalize charging to level out
the voltage between individual cells, improving battery performance and
lifespan.

Over time, the battery’s electrolyte can become stratified, causing inactive areas
in the plate material. If this condition is allowed to continue for extended periods,
the battery plates can sulfate and become unusable. Equalizing the batteries is a
controlled overcharging method that mixes up the electrolyte and reactivates the
unused areas of the plate material, restoring batteries to a full state of charge.

Consult the battery manufacturer’s recommendation for equalize charging

settings.

To start equalizing the batteries:

◆ On the device Setup menu, highlight Equalize and select Enabled.

NOTE: Only flooded or vented batteries should be equalize-charged.

Hydrogen and oxygen gases are produced when batteries are equalize-
charged. See warning below.

WARNING
EXPLOSION HAZARD
Provide adequate ventilation and remove all sources of ignition to prevent
explosion.
Failure to follow these instructions can result in death or serious injury.

Configuring Advanced Settings

IMPORTANT: In a system where more than one device is capable of equalizing

batteries (such as a system including multiple Conext SW units and Solar Charge
Controllers), there is no system-wide equalization command for all devices. To
equalize with multiple devices, each would have to be enabled individually.
Alternatively, equalization can be performed using only one device. During the
equalization process, one device applies the equalization charge while the other
devices continue to operate in synchronized charge mode, typically in float
(three-stage charging) or no-float (two-stage charging).

Using Charger Block

The Charger Block feature halts charging for a period of time each day. This
period of time is defined by the Chg Block Start and Chg Block Stop settings.
In areas where the utility charges variable rates for electricity, it is preferable to
use utility power for charging only during non-peak hours. Charger Block can
prevent utility power from being used for battery charging during peak billing
periods. During the time period set between Chg Block Start and Chg Block
Stop, AC input continues to be passed through to the loads. Inverter operation
remains unaffected during the charger block period. During the Charger Block
period, no charging occurs even if the batteries discharge below the ReCharge
Volts setting. However, a Solar Charge Controller may charge batteries during
the Charger Block period.

If the charger is operating (that is, in Float, Absorption, Bulk, or Equalize stage) at
the Chg Block Start time, charging stops immediately and the charger enters
an idle state identical to No Float (see “Two-Stage” on page 4–16). When the
Charger Block period is over, the charger does not resume the charge stage that
Chg Block Start interrupted. Instead, if the batteries are above the ReCharge
Volts setting, the charger remains idle. If the battery voltage falls below the
ReCharge Volts setting during the Charger Block period, the Conext SW
Inverter/Charger begins a new charge cycle with the Bulk stage after the
Charger Block period has expired (at the Chg Block Stop time).

Setting the Chg Block Start and Chg Block Stop to the same time disables
Charger Block. Disabling Charger Block means that charging is allowed to occur
at any time when the right conditions for charging exist.

Gen Support Settings

GEN Support allows power to be automatically drawn from the batteries to assist
an AC generator to support heavy loads (that is, loads that exceed the available
current from the generator).

Generators have a limited output current and it is possible to reach this limit when
operating heavy loads. The Conext SW is designed to assist the generator when
heavy current demands load down the generator by supplying additional power
from the batteries.

In addition, the battery charger can reduce its charging current to the batteries
so the combined charge AC current and total load current does not exceed the
capacity of the generator or trip its output breakers or fuses.

NOTE: Running and start-up (peak) currents are limited to the maximum current
limits of the inverter.

AC In setting The Conext SW accepts only a single AC source - either from the grid or from a
generator. In a power system where the Conext SW is solely connected to the
grid and an AGS is neither present nor required, the AC In setting can be either
Gen1 or Grid1. Therefore, the default value of Gen1 need not be changed.

In a situation where the AC source is a generator and the AGS is being used to
start the generator to produce AC power, the AC In setting must be set to Gen1.
Therefore, the default value of Gen1 must remain unchanged.

In a power system where the two AC sources are available but only one AC
source can be used, an external transfer switch becomes necessary. When an
external transfer switch is used and an AGS (with a B+ signal connection) is also
present, change the AC In setting to Grid1.

Troubleshooting

General Troubleshooting Guidelines

This section will help you narrow down the source of any problem you may
encounter. Please read the following troubleshooting steps:

1. Check for a warning or fault detection message on the SCP or a fault code on
the inverter information panel. If a message is displayed, record it
immediately.
2. As soon as possible, record the conditions at the time the problem occurred.
These details should include the following as well as any other information
asked for on the page. These details are:
• Firmware revision of the Conext SW
• Type of loads the Conext SW was running or attempting to run
• Battery condition at the time of fault detection (battery voltage or
temperature, for example), if known
• Recent sequence of events (for example, charging had just finished, AC
generator had stopped but the inverter did not come on)
• Any known unusual AC input factors such as low voltage or unstable
generator output
• Extreme conditions which may have existed at the time (temperature or
moisture, for example)
3. Attempt the solution indicated in these guidelines.
4. If your inverter front panel or SCP is not displaying a Fault detection light,
check the following list to make sure that the present state of the installation
allows proper operation of the unit. Read these guidelines carefully.
❐ Is the Conext SW located in a clean, dry, adequately ventilated area?
❐ Have the AC input breakers opened? If so, your pass-through load may have
exceeded the rating of one or more of the input breakers.
❐ Are the battery cables adequately sized and short enough? See the
Installation Guide for more information.
❐ Is the battery in good condition and are all DC connections tight?
❐ Are the AC input and output connections and wiring in good condition?
❐ Are the configuration settings correct for your particular installation?
❐ Are the display panel and the communications cable properly connected
and undamaged?
❐ Is the battery temperature sensor and its cable properly connected and
undamaged?
5. Contact Customer Service for further assistance. Please be prepared to
describe details of your system installation and provide the model and serial
number of the unit. See the front and/or back of the manual for contact
information.

Inverter Applications

Inverter Applications
The Conext SW performs differently depending on the AC loads connected to it.
If you are having problems with any of your loads, read this section.

Resistive Loads Resistive loads are the easiest and most efficient to drive. Voltage and current
are in phase, which means they are in step with one another. Resistive loads
generate heat in order to accomplish their tasks. Toasters, coffee pots, and
incandescent lights are typical resistive loads. It is usually impractical to run
larger resistive loads—such as electric stoves and water heaters—from an
inverter due to their high current requirements. Even though the inverter may be
able to accommodate the load, the size of battery bank will limit inverter run time.

Motor Loads Induction motors (AC motors without brushes) require up to six times their
running current on startup. The most demanding are those that start under load
(for example, compressors and pumps). Of the capacitor start motors (typical in
drill presses and band saws, for example), the largest you can expect to run is
1 horsepower. Universal motors are generally easier to start. Check that the
Locked Rotor Amps (LRA) rating of the motor load does not exceed the
maximum surge current rating of the inverter. Since motor characteristics vary,
only testing will determine whether a specific load can be started and how long it
can be run.

If a motor does not start within a few seconds or loses power after running for a
time, it should be turned off. When the inverter attempts to start a load that is
greater than it can handle, the inverter may shut down from an AC overload fault.

Problem Loads Very Small Loads If the power consumed by a device is less than the threshold
of the search mode circuitry, and search mode is enabled, the inverter will not
run. Most likely the solution will be to disable Search Mode or lower the sense
threshold.

Fluorescent Lights (CFL) and Power Supplies Some devices cannot be

detected when scanned by search mode circuitry. Small fluorescent lights are
the most common example. Some computers and sophisticated electronics have
power supplies that do not present a load until line voltage is available. When this
occurs, each unit waits for the other to begin. To drive these loads, either a small
companion load like a light bulb rated for more than the Search Watts setting
must be used to bring the inverter out of search mode, or the inverter may be
programmed to remain on by disabling Search Mode. (See “Using Search Mode”
on page 4–11.)

Clocks You may notice that your clocks are not accurate. Some of the clocks on
your appliances may reset when the Conext SW is in search mode.

Searching When the inverter is in search mode, it may not start some loads
even though the rated wattage on the load is more than the Search Watts
setting. Disable Search or apply an additional load (companion load) to make the
inverter exit search mode.

Troubleshooting the Conext SW via the SCP

Troubleshooting the Conext SW via the SCP

The Conext SW is designed with a number of protection features to provide
efficient operation. If, however, you have any problems operating your inverter/
charger read this troubleshooting chapter.

If you cannot resolve the problem, record the necessary information. This
information will help Customer Service to assist you better when you contact
them.

DANGER
ELECTRICAL SHOCK HAZARD
Do not disassemble the inverter/charger. The Conext SW contains no user-
serviceable parts.
Failure to follow these instructions will result in death or serious injury.

When a fault detection or warning message appears, you can acknowledge the
message to clear the screen. To acknowledge a fault detection or warning
message, press the Enter button on the SCP. This action does not clear the fault
detection or warning condition, so you should consult Table 5-3 for suggested
actions after you have acknowledged the message. Refer to the System Control
Panel Owner’s Guide for more information on faults and warnings.

Fault Detection Types

There are three types of fault detection messages: automatic, manual, and
escalating automatic. Table 5-1 describes how they differ in their behavior and
how you can respond to them when they appear on the SCP.

Table 5-1 Fault Detection Types and Behaviors

Fault Detection type Behavior
Automatic Clears automatically if the fault condition that
generated the message goes away. You can also
acknowledge automatic fault detections without
waiting for them to clear automatically.
Manual Require you to clear them by:

• pushing the Clear Fault button on the Conext SW

or on the device that generated the fault
detection (if the fault condition still exists, the
fault detection message reappears), and
• correcting the condition that caused the fault.

ConextSWEUROwnersGuide.book Page 6 Wednesday, December 5, 2012 10:33 AM

Troubleshooting

Table 5-1 Fault Detection Types and Behaviors

Fault Detection type Behavior
Escalating automatic Clears automatically if the fault condition goes away,
just like an automatic fault detection.

However, if an escalating automatic fault detection

occurs several times within a defined time period,
the escalating automatic fault detection becomes a
manual fault detection, requiring user intervention.
For example, if three fault detections occur in one
minute, it will no longer clear itself but becomes a
manual fault detection. Then you must identify the
problem, correct the fault condition, and clear the
fault detection or reset the device.

To view a list of the detected faults:

1. On the Select Device menu, highlight System and press Enter.

2. On the System Settings menu, highlight View Fault List.
3. Press Enter.

Warning Types
There are two types of warnings: automatic and manual. When the Conext SW
detects a warning condition, it displays a warning message on the SCP.

Table 5-2 describes how they differ in their behavior and in how you can respond
to them when they appear on the SCP.

Table 5-2 Warning Types and Behavior

Warning type Behavior
Automatic warning Clears automatically if the warning condition that
generated the message goes away. You can also
acknowledge automatic warnings without waiting
for them to clear automatically.
Manual warning Requires you to acknowledge it before you can
proceed with configuring or operating the Conext
SW. Manual warnings are usually in the form of a
Yes/No question that you may acknowledge by
pressing the Enter button on the SCP for Yes and
the Exit button for No.

Refer to the System Control Panel Owner’s Guide for

more information.
