20A Solar Charge Controller SRAB Series with Digital Display
A charge controller, or charge regulator is basically a voltage or current regulator to keep batteries from overcharging. It regulates the voltage and current coming from the solar panels going to the battery.

●CPU controlled with PWM function: able to adjust the charge current and decide if to supply the loads electricity according to the voltage of battery;
●Compensation charging: according to various system temperatures, the controller will automatically compensate the temperature of the charging voltage;
●LCD monitor: showing the charging current, battery voltage, environment temperature and real-time data of the charging process;
●Temperature sensor: probing the temperature of environment and indicating the degree of charging.
