Victron MultiPlus-II GX Inverter/Charger: Integrated Power and Monitoring for off-grid energy storage, marine, and mobile power systems

Advanced Inverter/Charger with Built-In GX Control

The Victron MultiPlus-II GX combines a powerful inverter/charger with an integrated GX monitoring device, delivering a complete energy management solution for off-grid energy storage, marine, and mobile power systems. This all-in-one unit provides pure sine wave AC power from your battery bank, intelligent battery charging from shore or generator, and seamless system monitoring via the built-in LCD and Wi-Fi connectivity. With PowerControl and PowerAssist technology, it prevents nuisance tripping of shore breakers and supplements limited grid or generator power with battery energy during peak loads.

Designed for demanding Australian conditions, the MultiPlus-II GX operates reliably from -40 to +65 °C with fan-assisted cooling. Its robust steel enclosure (RAL 5012 blue) and IP22 protection make it suitable for protected installations in vehicles, vessels, and off-grid buildings. The integrated GX device provides VE.Can, USB, Ethernet, VE.Direct, and Wi-Fi interfaces, enabling remote monitoring and control via the Victron Remote Management (VRM) portal and the VictronConnect app.

Key Features

• Integrated GX device with 2 x 16 character LCD for real-time system status
• PowerControl and PowerAssist prevent shore breaker trips and boost weak grid/generator supplies
• Pure sine wave output with 5500 W peak power for demanding loads
• Multi-stage adaptive charging with 35 A charge current for rapid battery replenishment
• VE.Bus communication for parallel and three-phase operation (only one GX unit needed)
• Dual AC outputs: one 'no-break' output for critical loads, one programmable auxiliary output
• Comprehensive connectivity: VE.Can, USB, Ethernet, VE.Direct, Wi-Fi
• Wide DC input voltage range: 38-66 V
• Programmable relay and two general-purpose communication ports for custom integrations
• Battery temperature sensor included for temperature-compensated charging

Intelligent Power Management

The MultiPlus-II GX excels in managing limited AC sources. PowerControl automatically adjusts battery charging current to prevent overload of the shore or generator supply, while PowerAssist instantly supplements the AC source with battery power when demand exceeds the available current. This is invaluable for off-grid energy storage, marine, and mobile power systems where shore power is often limited, allowing you to run high-power appliances without tripping breakers or needing a larger generator.

Seamless System Integration

With the built-in GX device, you can monitor and control your entire energy system from anywhere. The LCD displays battery state of charge, inverter load, solar input, and more. Connect via Wi-Fi to the VictronConnect app for configuration and live data, or use the VRM portal for advanced logging and remote firmware updates. The VE.Can port interfaces with compatible CAN-bus batteries and Victron VE.Can MPPTs, while VE.Direct connects to additional Victron devices. Ethernet provides a stable wired network connection for permanent installations.

Reliable Power for Critical Loads

The MultiPlus-II GX features a dedicated 'no-break' AC output that maintains power to essential equipment during grid failures or when switching between shore and inverter power. The transfer switch operates in less than 20 milliseconds, ensuring computers, medical devices, and other sensitive electronics continue without interruption. This makes it ideal for off-grid energy storage, marine, and mobile power systems where uptime is critical.

Built for Australian Conditions

Engineered to withstand harsh environments, the MultiPlus-II GX operates in temperatures from -40 to +65 °C and up to 95% non-condensing humidity. The fan-assisted cooling ensures reliable performance even under sustained high loads. The steel enclosure with RAL 5012 blue powder coating provides durability and corrosion resistance for mobile and marine applications.
