Product Description
PWM 20A 12/24V Solar Charge Controller (QWP-1420SLC)

The solar controller is the most important part of the solar system. It is too intelligent and automatically to control the charge, discharge and load of the system. The performance of the controller can influence the stability of the system, especially the lifetime of Battery.

This series solar controller will supply perfect protection functions for the battery; It will make battery work reliability. And the controller could be widely used in the solar system such as lamps, pastoral, frontier and island and so on, it is also could be used for mobile basics, microwave stations and traffic systems.

Theory introduction: Use the industrial MCU as the host controller.

1. Microcontroller digital accuracy
2. PWM charge mode
3. State of charge (SOC)
