Read MoreThe Victron MultiPlus-II GX combines a powerful sine-wave inverter, an adaptive multi-stage battery charger and an integrated GX monitoring device in a single enclosure — a complete energy-storage and backup-power solution without the clutter of separate components. When grid or generator power fails, it transfers to battery power fast enough to keep critical loads running uninterrupted.
Applications:
The MultiPlus-II GX is built for systems where reliable power and remote oversight matter:
- On-grid and off-grid energy storage: optimise self-consumption and, where required, prevent grid feed-in using an external AC current sensor or power meter.
- Backup and UPS: keep essential loads powered through outages with seamless transfer.
- Marine and mobile: deliver clean, stable 230 VAC power in vehicles, boats and remote installations.
- Solar self-consumption: pair with MPPT or PV-inverter topologies to store excess solar and draw it back when needed.
Why choose the MultiPlus-II GX?
The integrated GX device adds a 2 x 16 character display plus BMS-Can, USB, Ethernet and VE.Direct interfaces and Wi-Fi, so battery, inverter and solar data is visible locally or from anywhere via the free VRM portal. PowerControl and PowerAssist intelligently manage limited shore or generator supply, and only one GX unit is required across parallel and three-phase systems — making the MultiPlus-II GX a scalable foundation for serious power installations.
Features
- Inverter, Charger & GX in One: Combines a sine-wave inverter, adaptive battery charger and integrated GX monitoring device, reducing component count and wiring complexity.
- Uninterrupted Backup Power: Transfers to battery power fast enough to keep critical loads running through grid or generator outages.
- PowerControl & PowerAssist: Intelligently caps and boosts limited shore or generator supply to avoid tripping while drawing on battery reserves when demand peaks.
- Self-Consumption Optimisation: Works with an external AC current sensor or power meter to maximise use of stored solar energy and, where required, prevent grid feed-in.
- Integrated Monitoring & Wi-Fi: Built-in 2 x 16 display plus BMS-Can, USB, Ethernet and VE.Direct ports, with local and remote visibility through the free VRM portal.
- Scalable Architecture: Supports parallel and three-phase operation with only one GX unit needed for the whole system.
- Managed Battery Compatibility: BMS-Can interface connects to compatible CAN-bus managed lithium batteries.
- Rugged, Quiet Design: Steel IP22 enclosure with fan-assisted cooling and comprehensive overload, short-circuit and temperature protection.
