ROCKSOLAR 20 A PWM Solar Charge ControllerA 20 A PWM controller for a small 12 V or 24 V solar setup: one or two 12 V-nominal panels keeping a battery topped up on a boat gate opener shed or parked RV. It is sealed to IP67 so it can live outdoors in the weather.A PWM controller connects the panel to the battery directly and pulses the connection to regulate charge. It is simple and reliable but it cannot use any panel voltage above the battery voltage so it suits 12 V-nominal panels and arrays under about 250 W at 12 V.
