The Victron SmartSolar MPPT 100/30 is a 100 V, 30 A maximum power point tracking charge controller for off-grid and mobile solar systems. It handles up to 880 W of panel power and uses Bluetooth to set up and monitor charging from the VictronConnect app. Its key edge over budget MPPT controllers is the adaptive multi-stage charging, load output and detailed history logging. It suits van, boat and cabin builds where reliability and remote monitoring matter more than the lowest cost.
