$30 · Go Power 30 Amp Solar Controller (RV, Travel Trailer, Camper Van) Works Great

I've upgraded to the latest bluetooth model of the same brand, so I no longer need this one. Works perfectly! I used it in a Heartland Travel Trailer with 2 100w solar panels. Product Overview MODEL: GP-PWM-30-UL A solar charge controller is an essential component of your photovoltaic (PV) system. The controller maintains the life of the battery by protecting it from overcharging. When your battery has reached a 100% state of charge, the controller prevents overcharging by limiting the current flowing into the batteries from your solar array. Features: 12 volt flush mounted PV charge controller rated for a continuous solar current input of 30 amps. Uses pulse width modulation (PWM) technology Unique four stage charging system with optional equalize setting, to charge and protect your battery bank LCD digital display that shows solar array charge current, system battery voltage and battery capacity Built-in USB charge port Connects up to 600 watts total Charges 1 or 2 battery banks Remote on/off control of Go Power! inverters* (certain models) Maximum Power Boost Technology Our 30 Amp Digital Solar Controller features Maximum Power Boost Technology (MPBT). This allows you to override the normal charging algorithm of the solar controller to 'boost' the solar charge, which is ideal at the end of the daylight to ensure batteries are topped up for the evening. Performance of the solar controller will not be affected if MPBT function is not utilized.
