Operating During Transition Between Grid Mode and Battery Mode
The Freedom X’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 X automatically detects when shore power is present
and when it becomes unavailable or drops to less than 90 volts AC.
The transfer time can be set to two settings. For details see
“Adjusting Feature Settings in Configuration Mode” on page 45.
Transitioning from Grid Mode to Battery Mode
When the unit is operating in grid mode and shore power is lost, the
Freedom X has less than 20 milliseconds (default) to switch to
operating in battery mode (if the Power button is pressed in the On
position) and starts drawing power from the battery.
The operating mode indicator will change to Battery Mode and the
green Status LED for Battery Mode will light up.
However, if the Power button is in the Off position, this transition
does not happen and the display panel turns off.
Transitioning from Battery Mode to Grid Mode
When the unit is operating in Battery Mode and shore power
becomes available, the Freedom X 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 X will switch to shore power mode within 20 milliseconds
and start drawing power from the AC source.
The operating mode indicator will change to grid mode and the
green Status LED for grid mode will light up.
