Victron MultiPlus-II - 120-50 - 120V - 12/3000

The Victron MultiPlus-II - 120-50 - 120V - 12/3000 is a marine-grade inverter-charger purpose-built for serious boaters who demand reliable auxiliary power and battery management at sea. Whether you're running a fishing charter, living aboard, or maintaining power during extended time away from shore-based infrastructure, this unit delivers the dual functionality of high-capacity power inversion and intelligent battery charging in one compact package. The 120-volt, 3000-watt output handles everything from navigation electronics and galley equipment to fish-finders and cabin systems without compromise.

The MultiPlus-II architecture integrates Victron's proven inverter and multi-stage charger technology, allowing seamless switching between battery power and onboard AC sources—AC generator, shorepower, or solar integration through compatible Victron components. The 12-volt DC input draws from your vessel's battery bank with efficient power conversion, while the charger function maintains battery health through adaptive charging profiles that prevent overcharge and extend cycle life in the harsh marine environment. Built-in transfer switching automatically prioritizes available AC sources, reducing fuel consumption and generator run time while keeping your batteries fully charged. The rugged industrial design and compact 14 x 10 x 25-inch footprint fit neatly in engine rooms, lazarettes, or electrical compartments without demanding excessive space.

This unit is ideal for fishing boats, trawlers, and cruising sailboats where reliable power independence is non-negotiable. The 50-amp charger output ensures fast battery recovery between passages, critical for anglers who run multiple sonar systems, live-wells, and cabin loads throughout the day. Victron's monitoring ecosystem—compatible with the Color Control GX or VRM portal—gives you real-time insights into power flow, battery state of charge, and system diagnostics from the helm or your smartphone. Professional installers and experienced boat owners appreciate the modular design, stackable architecture for higher capacity systems, and Victron's reputation for marine-grade durability. The 54-pound weight requires proper mounting but reflects the quality transformers and components that ensure this inverter-charger will perform reliably for decades on the water.
