1 Important Safety Information
Read all of the instructions and cautions in the manual before
beginning installation.
There are no user serviceable parts inside the controller. Do not
disassemble or attempt to repair it.
Install external fuses/breakers as required.
Disconnect the solar module and fuse/breakers near to battery before
installing or adjusting the controller.
Do not allow water to enter the controller.
Confirm that power connections are tightened to avoid excessive
heating from loose connection.

3 Installation Instructions
3.1 Mounting
Read through the entire installation section first before beginning
installation.
Be very careful when working with batteries. Wear eye protection.
Have fresh water available to wash and clean any contact with
battery acid.
Uses insulated tools and avoid placing metal objects near the
batteries.
Explosive battery gasses may be present during charging. Be certain
there is sufficient ventilation to release the gasses.
Avoid direct sunlight and do not install in locations where water can
enter the controller.
Loose power connections and/or corroded wires may result in
resistive connections that melt wire insulation, burn surrounding
materials, or even cause fire. Ensure tight connections and use cable
clamps to secure cables and prevent them from swaying in mobile
applications.
Use with Gel, Sealed or Flooded batteries only.
Battery connection may be wired to one battery or a bank of batteries.
The following instructions refer to a singular battery, but it is
implied that the battery connection can be made to either one
battery or a group of batteries in a battery bank.
Select the system cables according to 3.5A/mm2 current density.

3.2Wiring
1. Connect components to the charge controller in the sequence as
shown in above picture and pay much attention to the “+” and
“-”.Always power the battery First.
2. After power the battery, check the battery indicator on the
controller, it will be green. If it’s not green, please refer to chapter
5.
3. The load should be DC applicant with the same rated voltage as
battery’s. Controller offers power to loads through the battery
voltage.

4.2 Setting Operation
Load Work Mode Setting
When the controller is powered on, press the setting button to control
the load output. Press the button once, the ON/OFF status will be
changed corresponding.
Battery Type Setting
Press the setting button for more than 5 seconds, battery indicator
LED1, LED2, LED3 will be flashing correspondingly. Then press the
setting button to choose Sealed, Gel, and Flooded battery type, when
you finish choosing, stop pressing the button, the setting is finished till
the digital tube stop flashing. The parameters indicated are shown

5 Protection and Troubleshooting
5.1 Protection
·
Load Overload
If the load current exceeds 1.25 times of rated current for 60 seconds,
or the load amp is 1.5 times of rated current for 5 seconds, the
controller will disconnect the load. Overload must be cleared up
through powering on again or pressing the setting button.
·
Load Short Circuit
Fully protected from load wiring short circuit (exceeds 2 times of
rated current) automatically. One automatic load reconnect attempt,
the fault must be cleared by reapply power or pressing the setting
button.
·
Battery Reverse Polarity
Fully protection form battery reverse polarity, no damage to the
controller will result. Correct the mistake of wiring to resume normal
operation.
·
Damaged Local Temperature Sensor
If the temperature sensor short-circuited or damaged, the controller
will be charging or discharging at the default temperature 25℃ to
prevent the battery damaged from overcharging or over discharged.

·
High Voltage Transients
PV is protected from high voltage transients. In lightning prone areas,
additional external suppression is recommended.
