SF040 – Solar Charger Controller – PWM 12/24V 50A

A solar charge controller plays an important role in prolonging the life of your solar battery. They protect batteries from the dangers of being overcharged and completely drained, both of which significantly reduce battery lifespan. The PWM charge controller is a good low cost solution for small systems, when solar cell temperature is moderate to high (between 45°C and 75°C).
