The Victron Energy BlueSolar MPPT charge controller efficiently converts sunlight into usable energy while optimizing battery life. Its fast MPPT technology and intelligent charge algorithms maximize power output, even when panels are partially shaded, and continuously monitor voltage and current to harvest every bit of available energy. Remote monitoring and control are possible via the VictronConnect app using an optional Bluetooth dongle (Bluetooth is not built-in; SmartSolar models include it). For safety, installation should be done by a licensed professional following all applicable electrical codes.
