 WARNING: Shock Hazard

Installation must be performed with care due to high battery voltage in series.

CAUTION!! Do not place anything between the flat part of the inverter terminal Otherwise,
overheating may occur.

CAUTION!! Do not apply anti-oxidant substance on the terminals before terminals are
connected tightly.

CAUTION!! Before making the final DC connection or closing DC breaker/disconnector, be sure

positive (+) must be connected to positive (+) and negative (-) must be connected to negative

(-).

AC Input/Output Connection
CAUTION!! Before connecting to AC input power source, please install a separate AC breaker between
inverter and AC input power source. This will ensure the inverter can be securely disconnected during
maintenance and fully protected from over current of AC input. The recommended spec of AC breaker is 50A.
CAUTION!! There are two terminal blocks with “IN” and “OUT” markings. Please do NOT mis-connect input
and output connectors.

WARNING! All wiring must be performed by a qualified personnel.

WARNING! It’s very important for system safety and efficient operation to use appropriate cable for AC input
connection. To reduce risk of injury, please use the proper recommended cable size as below.

Please follow below steps to implement AC input/output connection:
1. Before making AC input/output connection, be sure to open DC protector or disconnector first.
2. Remove insulation sleeve 10mm for six conductors. And shorten phase L and neutral conductor N 3
mm.
3. Insert AC input wires according to polarities indicated on terminal block and tighten the terminal
screws. Be sure to connect PE protective conductor ( ) first.
→Ground (yellow-green) L→LINE (brown or black) N→Neutral (blue)

WARNING:

Be sure that AC power source is disconnected before attempting to hardwire it to the unit.

4. Then, insert AC output wires according to polarities indicated on terminal block and tighten
terminal screws. Be sure to connect PE protective conductor ( ) first.
5. This inverter is equipped with dual output. There are four terminals (main out-L/N, second out-
L/N) available on output port. It’s set up through LCD program or monitoring software to turn on and
off the second output in program 43. Refer to “LCD setting” section for the details in program 29 and
31.

Remark:

1). The main output usually carries heavy loads which make the battery discharge time faster, the
heavy loads are such as air-conditioners, heaters, motors and so on.

2). The second output usually carries light loads which make the battery discharge time longer, the
light loads are such as lights, computers, fans and so on.

3). Normally, the cutoff point of second out is lower than main-out, so that the light loads will not be
cut off power.

 6. Make sure the wires are securely connected.
CAUTION: Important
Be sure to connect AC wires with correct polarity. If L and N wires are connected reversely, it may cause
utility short-circuited when these inverters are worked in parallel operation.

CAUTION: Appliances such as air conditioner are required at least 2~3 minutes to restart because it’s required
to have enough time to balance refrigerant gas inside of circuits. If a power shortage occurs and recovers in
a short time, it will cause damage to your connected appliances. To prevent this kind of damage, please check
manufacturer of air conditioner if it’s equipped with time-delay function before installation. Otherwise, this
inverter/charger will trig overload fault and cut off output to protect your appliance but sometimes it still causes
internal damage to the air conditioner.

 PV Connection
CAUTION: Before connecting to PV modules, please install separately a DC circuit breaker between inverter
and PV modules.

WARNING! All wiring must be performed by a qualified personnel.

WARNING! It'’ very important for system safety and efficient operation to use appropriate cable for PV module
connection. To reduce risk of injury, please use the proper recommended cable size as below.

BATTERY EQUALIZATION
Equalization function is added into charge controller. It reverses the buildup of negative chemical effects like
stratification, a condition where acid concentration is greater at the bottom of the battery than at the top.
Equalization also helps to remove sulfate crystals that might have built up on the plates. If left unchecked, this
condition, called sulfation, will reduce the overall capacity of the battery. Therefore, it’s recommended to
equalize battery periodically.

⚫ How to Apply Equalization Function

You must enable battery equalization function in monitoring LCD setting program 33 first. Then, you may apply
this function in device by either one of following methods:
1. Setting equalization interval in program 37.
2. Active equalization immediately in program 39.

⚫ When to Equalize
In float stage, when the setting equalization interval (battery equalization cycle) is arrived, or equalization is
active immediately, the controller will start to enter Equalize stage.

⚫ Equalize charging time and timeout

In Equalize stage, the controller will supply power to charge battery as much as possible until battery voltage
raises to battery equalization voltage. Then, constant-voltage regulation is applied to maintain battery voltage
at the battery equalization voltage. The battery will remain in the Equalize stage until setting battery equalized
time is arrived.

17
However, in Equalize stage, when battery equalized time is expired and battery voltage doesn’t rise to battery
equalization voltage point, the charge controller will extend the battery equalized time until battery voltage
achieves battery equalization voltage. If battery voltage is still lower than battery equalization voltage when
battery equalized timeout setting is over, the charge controller will stop equalization and return to float stage.
