Victron SmartSolar MPPT RS 450/200-MC4 Solar Charge Controller

The Victron SmartSolar MPPT RS 450/200 is Victron's largest solar charge controller: up to 450V of PV on four independent MPPT trackers, charging a 48V battery bank at up to 200A (11.52kW). The PV inputs are galvanically isolated from the battery, and it continuously monitors array insulation resistance and flags a fault if it drops. Four trackers let you put arrays with different orientations or shading on one controller. It has a built-in display, Bluetooth, VE.Can and VE.Direct, and up to 25 units can be synchronized over VE.Can for very large systems.
