Power Save Timer
The Power Save Timer is an adjustable countdown timer from 1 to
25 h (25 h is the default) that automatically shuts down inverter
operation to reduce battery discharge and preserve battery life.
During continuous inverter operation, the countdown is initiated
when power from the AC load drops to less than approximately
50 W and remains below this level. After reaching the end of the
countdown timer the inverter/charger automatically shuts down.
To change the countdown timer, see Settings on page 54.
Power Save Mode
By enabling the power save mode, also called load sensing, the
inverter/charger can automatically go to power save mode by
sending short pulses to further reduce the battery discharge.
Power save mode ends when a load greater than 25 W is
connected.
NOTE: Certain types of loads can cause power save mode to
work unexpectedly. These types of loads are described in
Problem Loads on page 83.

Checking Battery Status
During inverter operation (in battery mode), you can check the
battery status by observing the battery capacity indicator on the
LCD screen. The battery voltage appears in the left side of LCD
screen.
The normal operating battery voltage range is between 11 and
15 VZ.
Checking Output Power
When the inverter/charger is in operation (in battery mode), you
can check how much power (displayed in kW) the Freedom XC is
supplying to the connected loads by observing the load capacity
indicator on the LCD screen. The battery discharge amperage
appears in the right side of the LCD screen.
Operating Several Loads at Once
If you are going to operate several loads from the Freedom XC,
turn them on one at a time after you have turned the
inverter/charger on.
Turning loads on separately helps to ensure that the
inverter/charger does not have to deliver the starting current for all
the loads at once.
