Victron MultiPlus Inverter/Charger 24VDC - 3000VA -120VAC w/ 70-AMP Battery Charger - 50AMP Transfer Switch

The Victron MultiPlus Inverter/Charger 24VDC – 3000VA – 120VAC with 70-amp battery charger and 50-amp transfer switch is purpose-built for serious cruisers, liveaboards, and expedition vessels that demand reliable power independence on the water. After decades running offshore and in remote anchorages, any experienced boater knows that shore power isn't always available—and when equipment fails mid-passage, there's no quick trip to the marina. This dual-function unit solves that problem by combining pure sine-wave inverter capability with intelligent battery charging and seamless AC transfer switching in a single, compact chassis designed to withstand the salt-spray and vibration environment of working boats.

The 3000-watt inverter converts your vessel's 24-volt DC battery bank into clean 120-volt AC power to run essential systems—electronics, refrigeration, water heaters, and galley appliances—whether you're at anchor or underway. The integrated 70-amp battery charger rapidly replenishes your house bank from a dockside or onboard generator, ensuring you maintain reserve capacity for critical systems during extended passages. The 50-amp automatic transfer switch seamlessly selects between inverter output and shore power (or genset AC input), eliminating the need for manual switchover and preventing backfeeding into shore systems—a critical safety feature for any marine installation. Built on Victron's proven three-stage charging algorithm, the unit delivers exactly what your lithium or lead-acid battery chemistry requires: bulk, absorption, and float modes that maximize lifespan and performance in the demanding thermal environment of a boat's engine compartment or cabin.

This inverter/charger is ideal for 24-volt systems typical of larger cruising sailboats, trawlers, and expedition powerboats where AC demand exceeds what solar alone can provide. Installation requires a dedicated 24V DC circuit with appropriately sized battery cables and DC disconnect; your electrician should verify proper grounding and bonding per ABYC standards before commissioning. The unit pairs seamlessly with Victron's ecosystem of battery monitors, VE.Bus assistants, and network products, allowing you to monitor state of charge and system load remotely via smartphone—invaluable when optimizing power budgets during extended offshore passages or winter layups.
