Solar Voltage Regulator

Solar Voltage Regulator

Product name:PWM solar charge controller 20A
Model No.:CL12/24- 20DU
Working principle:PWM Solar Charge Controller is a photovoltaic (PV) charge controller that tracks the PV array to deliver the available current for charging batteries. When charging, the Controller regulates battery voltage and output current based on the amount of energy available from the PV array and state-of-charge of the battery.
