Xantrex FREEDOM EX 4000 - 4000W Inverter/Charger 80A 120V/48VDC

The Xantrex FREEDOM EX 4000 – 4000W Inverter/Charger 80A 120V/48VDC is the marine-grade power solution that separates serious cruisers from weekend warriors. If you've spent years running a boat on extended offshore passages or managing a full-time liveaboard electrical system, you understand that shore power won't always be available—and dead batteries end your adventure fast. This inverter/charger bridges that gap, converting DC stored in your battery bank into clean 120V AC power while simultaneously charging those same batteries from any available AC source at a robust 80-amp rate.

Built around Xantrex's proven hybrid topology, the FREEDOM EX 4000 delivers a full 4000 watts of continuous inverter output—enough to run your galley microwave, air conditioning, water heater, and medical equipment simultaneously without tripping breakers. The 48VDC architecture is the marine industry standard for larger vessels because it minimizes voltage drop over long cable runs and reduces resistive heat loss in your battery compartment. On the charging side, that 80-amp input means you'll refill a 500Ah lithium bank from depleted to full in under seven hours when plugged into a 240V dock pedestal, dramatically faster than smaller chargers. The unit's integrated transfer switch automatically detects shore power and seamlessly transitions your loads without interruption or audible relay clicks that annoy crew trying to sleep.

Cruisers operating in remote anchorages, liveaboards dependent on generator runtime reduction, and commercial fishing operations will recognize immediately why this inverter/charger justifies its weight and real estate in the engine room. The 17 x 12 x 21-inch footprint requires careful planning in tight galleys, but experienced installers know the FREEDOM EX 4000 mounts securely and integrates with both lithium and lead-acid chemistry via programmable parameters. Warranty support and spare-parts availability make Xantrex the trusted name when your electrical system must perform reliably thousands of miles from the nearest service center. This is the inverter/charger chosen by long-distance cruisers who refuse compromise on power quality or charging speed.
