Operating During Transition Between Shore Power and Inverter Mode

The Freedom HFS'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 HFS 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 HFS has less than 40 milliseconds to switch to
operating in 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 HFS begins a 20-second
countdown to verify the stability of the shore power. If shore power
remains stable for a 20-second countdown, at the end of the
countdown, the Freedom HFS will switch to shore power mode
within 40 milliseconds 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.
