The Xantrex Freedom HF 1800 (806-1840) is a compact, all-in-one power solution that combines an 1800-watt inverter, a 40-amp battery charger, and an automatic transfer switch. It is specifically designed for the demanding environments of RVs, boats, and heavy-duty trucks, offering a reliable way to run small appliances and entertainment systems while on the move.

Product Overview

The Xantrex Freedom HF 1800 Inverter/Charger is one of the smallest and lightest units in its class, making it ideal for installations where space is at a premium. It utilizes modified sine wave technology to power devices like microwaves, TVs, and DVD players. Its "New Generation" design focuses on ease of installation with quick-connect AC terminals that eliminate the need for traditional strain relief clamps.

• Integrated Power System: Combines a powerful inverter and a 3-stage 40A charger in a single box to manage your battery bank and AC needs simultaneously.

• Ignition Lockout: A key safety feature that disables the inverter when the vehicle's ignition is off, preventing accidental battery drain.

• Automatic Transfer Switch: Features a 30-amp relay that seamlessly switches between battery power and shore power (utility power) when you plug in at a dock or campsite.

• Remote Monitoring: Includes a detachable digital display with a 25-foot cable, allowing you to monitor system status and battery voltage from a convenient location.
