Introducing the Victron MultiPlus-II 48/3000 35-50 120V — a versatile, intelligent inverter/charger designed to power modern hybrid and off-grid systems with unmatched reliability and flexibility.
All-in-One power management
-
PowerControl and PowerAssist: External current sensor option extends control to 100A, allowing the system to boost the capacity of a grid or generator. The MultiPlus-II monitors AC loads and uses any surplus for battery charging, preventing overload of the generator/grid.
- PowerAssist extends the same principle of PowerControl to cover peak power needs. When loads spike, it supplements with battery power; when the load decreases, spare power recharges the battery.
Two AC Outputs for smart distribution
-
Main output with no-break transfer: In the event of grid failure or when shore/generator power is disconnected, the MultiPlus-II seamlessly takes over in under 20 milliseconds so connected equipment keeps running.
-
Secondary output: Live only when AC input is available. Load that should not discharge the battery (e.g., water heaters) can be connected to this output.
Solar energy ready and grid-tie compatible
The MultiPlus-II is suitable for both off-grid and grid-connected PV systems. It works with solar charger controllers and grid-tie inverters, enabling AC power to be available from solar sources even if the grid is down in hybrid setups.
Virtually unlimited power with parallel, split phase and three-phase
Up to 6 MultiPlus units can be paralleled to increase total power. Six units of 48/3000/35 deliver about 15 kW / 18 kVA of output power with 210 A of charging capacity. For 240 V split-phase, use two units; for three-phase, use three units; and up to 6 sets of three units can be connected per phase.
On-site configuring, monitoring and remote management
Configure, monitor and control settings quickly with VEConfigure software (requires MK3-USB). You can monitor from Color Control GX, Venus GX, Octo GX, CANvu GX, or your computer. With optional VE.Bus dongle or other GX products connected to the internet, the system can be accessed remotely via Victron's VRM website, free of charge.
