PWM solar controllers are a simple, compact and cost effective way to prolong battery life and also protect the battery from overcharging, undercharging, short circuiting, and overheating in small and medium solar systems. Our carefully selected 20A PWM controller is ideal for solar charging a 12V or 24V lead acid battery bank and regulating output to a load such as a light or pump The controller can accept solar input of up to 320W (12V battery) and 640W (24V battery) making it an ideal solution for smaller PV systems used on boats and campervans. Compatible and easily connected with the MT50 remote Display to display system performance information from the controller and allows manual adjustment to parameters and load settings.
