Troubleshooting Protection Modes
The Inverter may shut down and cease supplying AC power under
certain conditions in order to protect the unit, the battery and
connected equipment.
The LED automatically illuminates green when the Inverter is plugged
into a 12V DC power source and turned on. If conditions cause the
Inverter’s Fault LED to illuminate red, its alarm to sound or the inverter
automatically turns itself off, follow these instructions to restore the
unit to normal operation:

Low-Voltage
Alarm and
Low-Voltage
Cutoff
Green: On
Red: Off
Yes When the power
input from
the vehicle’s
battery drops to
approximately
10.5V+/-0.3V
DC, the low-
voltage alarm
will sound. When
the voltage goes
down below 9.5V
+/- 0.3V DC, the
inverter shuts off.
Start the vehicle
to recharge the
battery. When the
voltage is above
12V+/-0.3V DC
at no load, the
inverter will
automatically
resume
operation.
Green: On
Red: On

Shutdown
Green: On
Red: On
Yes When the power
input from the
vehicle’s battery
exceeds 16V+/-
0.3V DC, high-
voltage overload
protection occurs
and shuts down
the inverter.
When the input
voltage drops to
14V +/- 0.3V
at no load, the
inverter will
automatically
resume
operation.
