Meet the Xantrex Freedom HF1800 1800W Inverter with 40A Charger — the next generation of mobile power that brings effortless versatility to boats, RVs, and trucks. Designed for quick, clean installation and minimal battery drain, Freedom HF redefines off‑grid convenience with intelligent features like quick‑connect AC terminals and ignition lockout.
Why Freedom HF1800 Stands Out
Smallest, lightest, and most affordable inverter/charger in its class, the Freedom HF1800 delivers reliable 1800 watts of continuous power with a robust 3600W surge to handle demanding loads. Its modified sine wave output is ideal for entertainment systems, microwaves, TVs, DVD players, and other small appliances on the move.
-
Power you can trust: 1800W continuous, 3600W peak with 115V/60Hz output and a wide 10.5–15.5V operating range.
-
Effortless installation: Quick-connect AC terminals on input and output eliminate messy wiring and strain relief clamps.
-
Ignition lockout: Minimizes battery drain by disabling the inverter when the ignition is off.
-
Remote system monitoring: Removable digital display with a 25-foot extension cable for convenient status checks from anywhere on the vessel or vehicle.
-
Smart charging: Three‑stage automatic battery charger with a 40A rate to rapidly restore power from 12V sources.
-
Automatic transfer: Built‑in 30A relay smoothly switches between inverter power and incoming AC utility power.
-
Protection you can rely on: Battery over/under‑voltage, over‑temperature shutdown, automatic overload, short‑circuit, and ground‑fault protections.
-
Safety certified: ETL certified to UL458 for mobile RV and commercial applications.
What You Can Run
Designed to power demanding loads and essential entertainment systems, the Freedom HF1800 is perfect for microwaves, TVs, DVD players, and other small appliances on boats, RVs, and trucks. With its compact form factor and remote monitoring, you get reliable power where and when you need it most.
