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.

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
