The Victron MultiPlus 12/1200/50 is a compact yet powerful inverter/charger combo that delivers reliable 230V AC power from a 12V battery. Designed for off-grid and backup systems, it combines a 1200VA pure sine wave inverter, a 50A battery charger, and a high-speed AC transfer switch in one robust unit. Its intelligent power assist function prevents overloads by boosting shore or generator power with battery energy. Easily configure and monitor the unit via VE.Bus with compatible GX devices or a computer. Whether for mobile, marine, or remote applications, the MultiPlus ensures seamless power management and efficient battery charging.
Features:
- True sine wave inverter, adaptive battery charger, and AC transfer switch in one unit.
- Supports up to 6 units in parallel or 3-phase configuration.
- PowerControl prevents generator or shore overload by managing power use.
- PowerAssist boosts limited shore/generator power with battery support during peaks.
- Four-stage adaptive charging for Lithium, AGM, Gel, and Flooded batteries.
- Dual battery charging for starter or auxiliary batteries.
- High start-up power for heavy loads like LED lamps and power tools.
- Search Mode reduces power consumption during low/no load.
- Programmable alarm relay and remote on/off control.
- Easy on-site setup with DIP switches; advanced remote monitoring via GX devices and VRM portal.
