PWM Solar Charge Controller 20A

The maximum current of SUNPOWER line controller can reach up to 40A at automatically recognized 12V or 24V. The circuit board is completely electronically protected and with the LED user interface, it is easy to check the battery voltage and all the fault message at any time. PWM and three-stage automatically controlled charging mode protect the battery well and realize a long-term best working state of the battery. With unique water-proof design, the controller can work well in moisture, rainy or even worse environment.
