Operating During Transition Between Shore Power and Inverter Mode

The allowable Freedom HF input voltage ranges are shown in the 
following table for Freedom HF 1500 and Freedom HF 1800 T:

Full Operating 
Range

Low, Mid, High:
12.1–15.5 volts

Low:
10.5–15.5 volts
Mid:
11.8–15.5 volts
High:
12.1–15.5 volts

Low refers to low limit of the low 
voltage threshold.
Mid refers to middle limit of the low 
voltage threshold.
High refers to high limit of the low 
voltage threshold.

Optimum 
Performance

12.1–13.0 volts

12.1–13.0 volts

Low Voltage 
Alarm

Low, Mid, High:
<12.6 volts

Low: <11.0 volts
Mid: <12.3 volts
High:<12.6 volts

A silent low battery warning shows 
fault code  on the display.

Low Voltage 
Shutdown

Low, Mid, High:
<12.1 volts

Low: <10.5 volts
Mid: <11.8 volts
High:<12.1 volts

A single one-second low battery 
alarm beeps and the display shows 
fault code . After five minutes, 
the unit shuts down completely.

Instant Low 
Voltage 
Shutdown

<10.2 volts

<10.2 volts

After two seconds below the limit, 
the unit shuts down and the low 
battery alarm sounds a long beep 
continuously for 30 seconds.

High Voltage 
Shutdown

15.5 volts or 
more

15.5 volts or 
more

The over-voltage alarm beeps every 
second and the display shows fault 
code  alternating with the battery 
voltage. The status LED turns red and 
the display screen is turned OFF 
within 30 seconds to protect itself 
from excessive input voltage.
NOTE: Although the Freedom HF 
incorporates over-voltage protection, 
it can still be damaged if input 
voltage exceeds 16 volts.
