Operating During Transition Between Shore Power and Inverter Mode
The Freedom HF’s advanced power management is capable of 
transitioning power from an AC source to DC source within a 
fraction of a second and vice-versa.
The Freedom HF automatically detects when shore power is present 
and when it becomes unavailable or drops to less than 90 volts AC.
Transitioning from Shore Power to Inverter 
Mode
When the unit is operating in shore power mode and shore power is 
lost, the Freedom HF has less than 30 milliseconds to switch to 
inverter mode and start drawing power from the battery.
The Status LED will turn from solid or flashing GREEN to a solid 
YELLOW.
Transitioning from Inverter Mode to Shore 
Power
When the unit is operating in inverter mode and shore power 
becomes available, the Freedom HF begins a 20-second countdown 
to verify the stability of the shore power. If shore power remains 
stable within 20 seconds, at the end of the countdown, the Freedom 
HF has less than 30 milliseconds to switch to shore power mode and 
start drawing power from the AC source.
The Status LED will turn from solid YELLOW to flashing 
YELLOW during the 20-second countdown, then turn to GREEN 
when battery power is transitioned successfully to shore power.
