Order of Connection:

① Connected with Battery first; ② Connected with Load; ③ Connected with Solar Panel.

Note:

① This series is a positive ground controller. Any positive connection of Solar Panel, Load or Battery can be earth grounded;
② The fuse should be installed as close to battery as possible, the suggested distance is about 150mm;
③ If inverter or other load with big start current is necessary in system, please connect it with Battery, not solar controller;
④ When disconnecting the system, the order will be reversed.

Operation:

LCD Symbol:

 

Button Function:

Browse Interface:

NOTE:

① After connected with Battery, LCD will go into an interface that automatically recognizes the battery voltage level, 3 seconds later, it will enter to the main interface of LCD;
② Equalizing charge will be after every 90 times Floating charge, or one charge in three months;
③ Default maximum charging current of Lithium battery is 5A, but it can be adjusted by users within the rated current range.
④ Under the interface of Accumulated KWH, long press button “+” to clear the value; ⑤When no operation 30s, the interface will be back to main interface, and back-light will be turned off.

Battery Types:

Under the interface of battery types, long press button “” into the type setting, then short press button “” or “” to choose battery type, and then long press “” again to save and exit.

Protections:

  • Solar Panel Reverse-Polarity: If the solar panel is connected with controller in reversed polarity, controller will not be damaged and will work as normal when correctly connected.
  • Battery Reverse-Polarity: If the battery is connected with controller in reversed polarity (solar controller is not connected with solar panel), controller will not be damaged and will work as normal when correctly connected.
  • Battery Reverse-Discharge: Controller is able to protect battery from reversed discharging to solar panel at night.
  • Over-Heating Protection: Once the internal temperature is detected to be higher than a certain value by the controller, it will stop charging the battery and then recharging the battery automatically after the temperature drop to a certain value.
  • Battery Over-Current: Controller will stop charging when excess current is detected from the solar panel, and recharging automatically after 2 min.
  • Load Over-Load: The load will be turned off when the output current of load exceeds its rated current for a while, and turned on automatically after 2 min.
  • Load Short-Circuit: Controller will be in protection state when the load is short circuit, and recharging automatically after 2 min.
  • Battery Low-Voltage: Controller will turn off the load when the battery voltage is lower than the value preset for low-voltage disconnection, and turn on the load when the battery voltage reaches the value preset for low-voltage re-connection. The value for low-voltage disconnection and low-voltage re-connection can be set by users in a certain range.
  • Battery Over-Voltage: Controller will turn off the load when the battery voltage is higher than the value preset for over-voltage protection, and turn on the load when the battery voltage is 1V lower than the value preset for over-voltage protection.
  • Lightning Protection: The lightning protection function of controller is limited and it is recommended to install devices for lightning protection on the input side to increase system reliability.

Troubleshooting:

Error Code

Cause

Solution
