Inverter Loads
The Freedom HW will operate most AC loads within its power rating of
1000 watts. 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 HW. 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
Warn ing When the Freedom HW’s AC load is approximately 100 W below the
overload shutdown limit of ~1000 W, the audible alarm beeps once every
two seconds and the display screen shows a fault code E06.
Overload
Shutdown When the Freedom HW’s AC load increases to near ~1100 W, 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 HW 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.
A single incandescent bulb requires five to ten times its power rating
when lighting up from a cold start. If you have several bulbs lighting up
all at the same time, then the surge is even greater.
A Compact Flourescent Light or CFL also has a momentary surge that is
more than ten times its power rating when lighting up from a cold start.
