Go Power! GP-MPPT-40 40 Amp MPPT Solar Controller

The Go Power! 40-Amp MPPT solar controller brings maximum efficiency in a smaller package. The most compact controller in its class, it 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. The GP-MPPT-40 optimizes solar charging capacity in mobile systems in all sun and tilt conditions while allowing the use simpler series wiring configurations up to 150V (VOC @ STC).
