Use Cases
The 48V compatibility makes this controller future-proof for caravanners upgrading their electrical system. Run it now on a 12V setup and transition to 24V or 48V without replacing the controller.
Off-road tourers building 48V lithium systems will appreciate this unit's three-voltage auto-detect. It also includes a load output — connect a DC fridge directly with low-voltage disconnect to protect the battery.
Yacht owners planning a future upgrade to 48V house bank will find the 100/20-48V covers all bases. The compact enclosure fits neatly in electrical panels where space is at a premium.
Ideal for hybrid off-grid cabins where you want to start small and scale up. Begin on a 12V/200Ah battery bank and expand to 48V later — the controller transitions with the system.
App Control & Connectivity
All SmartSolar MPPT controllers feature built-in Bluetooth for wireless monitoring and configuration via the free VictronConnect app (iOS and Android). Adjust charge settings, view real-time solar data, and receive alerts — all without needing a laptop or additional hardware. For advanced monitoring, connect to a Victron GX device (Cerbo GX, Venus GX) for full system integration and remote access via VRM.
