20A 12V/24V PWM Solar Charge Regulator Solar Panel Battery Controller 240W/480W

Build-in industrial micro controller.
One-key setting, digital display.
Fully 4-stage PWM Charge management.
Build-in short-circuit protection, open-circuit protection, reverse protection, over-load protection.
Automatically manage the working of solar panel and battery in solar system.

Under-voltage and over-charging protection. Protection from lightning strike.
Prolong the battery life cycle and keep the load work well.
This controller can charge and discharge at the same time. It has perfect SOC function, control charge current, and supply power to the loads.
The controller will automatically compensate the temperature of the charging voltage according to the changes of ambient temperature.
