Notes:
Before connecting to the solar panel, please connect the controller to the battery; do not use solar panel supply power to the loads directly.
Do not use lamplight to charge the solar panel (lamplight is too weak to charge)
DC power source to replace the solar panel will cause troubles to controller.
Choose the suitable wire which diameter should not be too small, please refer to the parameter.

Product Features

PWM solar charge controller PWM10-60: Compared with normal solar charge controller, this MPPT controller could increase efficiency by 10%-30%. When the battery voltage is low, the controller will automatically cut off the load from the system. If the voltage of battery is back to normal and the load will restart working. According to the battery voltage grade, the controller can automatically set charge-off voltage, the load-off voltage, the load- restore voltage. (The parameter is default under 25? condition, locked by the CPU procedure, cannot adjust.) The controller will automatically compensate the temperature of the charging voltage according to the changes of ambient temperature. Thunder protection;this controller can charge and discharge at the same time;this PWM controller has perfect SOC function, control charge current, and supply power to the loads.
