Operating During Transition Between Shore Power and Inverter Mode
975-0390-01-01 4–7
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 Vac.
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 ms (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 ms
(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.
