Operating During Transition Between Shore Power and Inverter Mode
Overload Conditions
There are two kinds of overload conditions:
• an overload warning
• an overload shutdown
Overload Warning When the Freedom HFS's AC load is
approximately 100 W below the overload shutdown limit of
~1000 W (for Freedom HFS 1055 models) or ~2000 W (for
Freedom HFS 2055 models), the audible alarm beeps once every
two seconds and the display screen shows a fault code .
Overload Shutdown When the Freedom HFS's AC load
increases to near ~1100 W (for Freedom HFS 1055 models) and
~2100 W (for Freedom HFS 2055 models), the audible alarm beeps
every second and the display screen shows a fault code . 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 HFS 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.

Over-temperature Conditions
During inverter operation, when the Freedom HFS's internal
temperature starts to approach its preset shutdown limit, the alarm
will beep every two seconds and the display will show fault code
. If the over-temperature condition persists, the alarm will beep
once per second and the display will show fault code . The
Status LED turns solid RED and the inverter will shut down to
prevent damage to the inverter and protect the battery from being
over-discharged. However, when the internal temperature drops and
falls within normal operating temperature, the Freedom HFS will
recover automatically and will continue inverting.
During AC shore power mode, when the Freedom HFS's charger
temperature starts to approach its limit, the charging current will be
reduced to 20 amps. If the temperature continues to rise, charger
output (charging current) is reduced to zero.
