Pwm Solar Charge Controller

Pwm Solar Charge Controller

Product name:PWM solar charge controller 30A
Model No.:CL12/24- 30DU
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.


30a pwm solar charge controller information

China promotion price 30a pwm solar charge controller 

Our CL series is an economical and traditional PWM solar controller. It can not noly extend the service life of battery, but also provide necessary protection over the whole system. We own its outlook design patent. The double buttons and LCD screen show you the working paramters of the whole system, clear and understandable. This series is widely applied in solar home system, traffic signal, solar lighting system etc.

Connection diagram

About 30 amps pwm solar charge controller 

1.Vivid LED indicators show system battery capacity,charging and discharging state of battery 

2.Protection functions such as overcharging,over discharging,overload and reverse connection.

3.PWM charging increases charging efficiency by 3% to 6%,compared with non-PWM charging.

4.The parameters of charging and discharging are preset,so no need to adjust the parameters. (special parameters need to be advised in advance)

5.USB output function

Application for solar charge controller
