Simple Solar Charge Controller

Simple Solar Charge Controller

Product name:PWM solar charge controller 10A
Model No.:CL12/24- 10DU
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.



10a pwm simple solar charge controller information

12V 24V 10a intelligent pwm simple 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.

Packaging for pwm solar charge controller

About 10amps simple solar charge controller

· Equipped with LCD display showing the working condition of system and parameters.

· When the battery voltage lower than reentrant boost voltage, will turn into boost charging automatically. 

· Double temperature sensor design, the internal temperature sensor detects the internal temperature of controller, the external temperature sensor detects the battery temperature, making the temperature compensation accurately. 

· The controller can calculate the amperage of charge and discharge current. 

· Protection for overload of charge current, it will reduce the charging current after exceeding the rated current to protect the circuit.

· Industrial level design, can be used in a variety of harsh environment.Parameter recovery function even after power cut.
