Solar Charge Controller PWM Waterproof 12V 20A 240W N2009

SKU: 9321758240755


This compact PWM 4 stage solar charge controller is ideal for 12V battery systems up to 20A input load. The entire PCB assembly is housed in an aluminium heatsink extrusion, which is epoxy filled for moisture & dust resistance.

The internal circuitry provides protection against several conditions which can potentially damage your battery or the controller itself. These include over charge, over discharge, over current, reverse polarity and short circuits. IP68 rated. Size: 82Wx45Dx21H mm
