Low Voltage
Shutdown
< LBCO
The buzzer sounds a single 1 s low battery alarm
beep and the LCD screen shows error code
E01
. After LBCO Shutdown delay timer runs out,
the unit shuts down inverter output. The buzzer
stops beeping and the LCD screen shows error

E01
.
Instant Low
Voltage
Shutdown
< 10.0 V
After 2 s below the limit, the unit shuts down
inverter output completely. LCD screen turns off
completely.
High Voltage
Shutdown
18.0 V
The display shows error code
E02
alternating
with the battery voltage. The red status LED
turns on.
NOTE:
Although the Freedom XC incorporates
over-voltage protection, it can still be damaged if
input voltage exceeds 32.0 VDC.
Overload Conditions
There are two kinds of overload conditions – an overload warning
and an overload shutdown.
Overload
Warning
When the Freedom XC’s AC load is approximately 100 W
below the overload shutdown limit of rated watts, the
audible alarm beeps once and the LCD screen shows a
warning code
E06
.
Overload
Shutdown
When the Freedom XC’s AC load increases to near
~1700 W, the audible alarm beeps every 5 s for 1 min
and the LCD screen shows a error code
E03
. The Status
LED turns solid RED.
High Surge Loads
Some induction motors used in freezers, pumps, and other motor-
operated equipment require high surge currents to start. The
Freedom XC may not be able to start some of these motors even
though their rated steady state current draw is within the
inverter/charger’s limits. The unit will shut down and indicate an
overload shutdown.
