Selectable Low Battery
Shutdown
The low battery shutdown for the inverter can be
manually selected by the user by choosing a low,
middle, or high setting. The low setting default for low
battery shutdown is10.5 volts except Freedom HF
1500 (PN: 806-1544).

Battery-friendly
Charging
For the inverter to perform effectively, the batteries
must be charged correctly. The Freedom HF hasa
built-in three-stage charging system that extends the
life and optimizesthe performance of the batteries. In
addition to the numerous features which let you
maximize your battery’s life and performance, the
Freedom HF—unlike many chargers—also has the
ability to recharge a near-zero voltage
e
battery and an
ignition-switched 20-amp auxiliary 12-volt power
source
f
.
Ignition Control The Freedom HF features the ability to inhibit the
inverter from operating in the absence of a voltage
signal from a vehicle's ignition circuit. Thisis particularly
useful if the inverter isrequired to operate only when a
vehicle's engine isrunning.
e
Near-zero or dead batteries can be recharged. However, some batteries which have been left uncharged
for days can become severely damaged thus, recharging is futile.
f
Available on the Freedom HF 1055 EMS model and Freedom HF 1800 EMS model. The inverter/charger
features a 20-amp fused and switched output voltage supplied from the inverter/charger's positive terminal.
When connected to a vehicle's ignition signal, a switched positive voltage is available to power auxiliary
circuits that are required to operate only when the vehicle is operational.
