Victron MultiPlus-II 24/3000 70-50 2x120V (UL458)

The Victron MultiPlus-II 24/3000 70-50 2x120V (UL458) is the inverter-charger that serious cruising boats and offshore vessels depend on when grid power isn't available. Built for marine environments where reliability matters as much as range, this unit combines true sine wave inverter output with intelligent battery charging—exactly what you need when anchored far from shore or running extended passages. Whether you're living aboard, running a fishing operation, or powering a superyacht tender, the MultiPlus-II handles the dual role seamlessly, switching between AC sources without dropping your circuits.

This 3000-watt unit delivers dual 120V AC output, giving you the flexibility to run two separate 120V circuits simultaneously—critical for powering galley equipment and cabin loads at the same time without compromise. The 24-volt DC input matches high-capacity lithium or lead-acid battery banks standard on larger displacement cruisers, while the 70-amp three-stage charger ensures your batteries recover quickly when generator or shore power becomes available. UL458 certification confirms marine-grade construction and safety standards, and the isolated transformer design protects sensitive electronics from AC distortion, voltage sags, and ground faults common in saltwater environments.

Cruisers, charter operators, and professional mariners prefer the MultiPlus-II for systems where space and weight matter but performance cannot. At 51.4 pounds and 14 × 10 × 25 inches, it fits engineroom and lazarette installations while delivering the AC independence you need during extended time at anchor. Installation requires 24V DC wiring to your battery bank and standard AC distribution panel integration; consult your marine electrician to ensure proper grounding and circuit protection for your vessel's specific electrical architecture. This is the standard by which marine inverter-chargers are measured.
