Victron Energy SmartSolar MPPT 100/50 Solar Charge Controller 12/24VDC at 50 Amps

Victron Energy SmartSolar MPPT 100/50 Solar Charge Controller 12/24VDC at 50 Amps (SCC110050210)

Now with built-in Bluetooth. The MPPT controller is a sophisticated way to harvest the maximum power from a solar array. It adjusts its input voltage to the optimal level for maximum power production. It decouples the solar array voltage from the battery voltage so that a 48 volt panel can power a 24 volt battery bank
