Inverter Loads
The Freedom HF will operate most AC loads within its power rating of
1000 watts (Freedom HF 1000) or 1800 watts (Freedom HF 1800).
However, some appliances and equipment may be difficult to operate, and
other appliances may actually be damaged if you try to operate them with
the Freedom HF. Please read “High Surge Loads” and “Trouble Loads”
carefully.
Overload Conditions
There are two kinds of overload conditions:
• An overload warning and
• An overload shutdown.
Overload
Warning
When the Freedom HF’s AC load is approximately 100 W below the
overload shutdown limit of ~1000 W (Freedom HF 1000) and ~1800 W
(Freedom HF 1800), the audible alarm beeps once every two seconds and
the display screen shows a fault code E06.
Overload
Shutdown
When the Freedom HF’s AC load increases to near ~1100 W (Freedom
HF 1000) and ~2000 W (Freedom HF 1800), the audible alarm beeps
every second and the display screen shows a fault code E03. The Status
LED turns solid RED and in 30 seconds, both the unit and the display
screen will shut down to prevent damage to the inverter and protect the
battery from being over-discharged.
High Surge Loads
Some induction motors used in freezers, pumps, and other motor-operated
equipment require high surge currents to start. The Freedom HF may not
be able to start some of these motors even though their rated steady state
current draw is within the inverter’s limits. The unit will shut down and
indicate an overload shutdown.
