Operating During Transition Between Shore Power and Inverter Mode

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 .

Overload Shutdown When the Freedom HF’s AC load increases to near ~1100 W (Freedom HF 1000 models) and ~2000 W (Freedom HF 1800 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 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.

Over-temperature Conditions

During Inverter mode, when the Freedom HF’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 HF will recover automatically and will continue inverting.

During AC shore power mode, when the Freedom HF’s charger temperature starts to approach its limit, the charging current will be reduced to 10 amps (Freedom HF 1000 models) or 20 amps (Freedom HF 1800 models).

The Freedom HF also monitors the internal transfer relay temperature. It automatically turns on the fan when the relay starts to approach its preset temperature limit and turns off when it cools down. If the relay exceeds its preset temperature limit, the display shows a fault code . See “To reset error codes  to :” on page 35.
