Victron MultiPlus-II 48/5000 70-95 120V (UL1741)

The Victron MultiPlus-II 48/5000 70-95 120V (UL1741) is a hybrid inverter-charger purpose-built for serious cruising anglers and liveaboard boaters who demand reliable, efficient power management in remote waters. This unit transforms your vessel's 48-volt battery bank into a complete power ecosystem, seamlessly switching between solar-charged DC power, onboard alternators, and shore power while intelligently managing loads that would otherwise drain your batteries in hours. For anyone spending extended time away from the dock—whether chasing tarpon in the Everglades, working offshore, or anchored in backcountry flats—this inverter eliminates generator noise, fuel consumption, and the constant vigilance required to protect battery voltage.

The Victron MultiPlus-II delivers a continuous 5000-watt output at 120V, with a peak surge capacity rated between 70–95 amps, allowing you to run heavy-draw equipment simultaneously—refrigeration, electric winches, microwave ovens, and water pumps without voltage sag. Its four-stage smart charging algorithm optimizes battery lifespan by precisely matching charge current to battery chemistry and temperature, while dual AC inputs allow automatic switching between shore power and a backup generator. The UL1741 certification ensures compliance with North American grid-tie standards, and its integrated Transfer Relay automatically disconnects or reconnects your battery bank to shore/generator power with zero interruption to critical loads, keeping fish finders, navigation systems, and galley appliances running continuously throughout every transition.

Serious cruisers, commercial fishing operators, and liveaboard anglers benefit most from this inverter's reliability in harsh saltwater environments and its seamless integration with Victron's ecosystem of solar controllers, battery monitors, and remote management systems. Installation on a 48-volt lithium or lead-acid bank requires proper marine-grade cabling, a qualified installer familiar with high-voltage DC systems, and compliance with ABYC marine electrical standards. The compact form factor fits into standard engine-room or battery-box locations, and its silent operation—with no exhaust or fuel consumption—preserves the quiet necessary for sight-casting and trolling. Compatibility with Victron's Color Control GX and smartphone monitoring apps puts real-time battery state-of-charge and system diagnostics in your wheelhouse, allowing confident, informed decisions about power budgets during multi-day expeditions.
