Xantrex Freedom HF 1800 Modified Sine Inverter Charger

The Xantrex Freedom HF 1800 is a modified sine wave inverter charger with a three-stage charger, 30A transfer relay and detachable display.

The detachable digital display can be mounted remotely, which is what makes the unit practical where it has to go somewhere awkward. An inverter charger belongs near the batteries, and that is rarely somewhere anyone can read a screen. Separating the display solves that without a separate remote panel to buy.

Temperature-controlled three-stage charging adjusts to battery temperature rather than following a fixed profile. That matters because the correct charging voltage changes with temperature, and a fixed-voltage charger overcharges a hot battery and undercharges a cold one.

It can be hardwired or connected through the included GFCI receptacle arrangement, giving flexibility on how the AC side is finished. Modified sine wave suits entertainment systems, microwaves and small appliances rather than sensitive electronics, with protection covering battery over-voltage, under-voltage and over-temperature.
