BATTERY
Solid Red
Battery warning condition. Battery voltage is
below 10.5 volts DC or above 15.0 volts DC.
Blinking Slowly
(once a second)
Unit has shutdown. Battery voltage is either
below 10.0 volts DC or above 15.5 volts DC.
Blinking Rapidly
(five times a
second)
Potential problem in the DC system has been
detected.
Check batteries, battery cables and DC loads.
No Light
Battery voltage is normal, i.e., between 10.5 and
15.0 volts DC.
OVERTEMP/

too high. Unit will automatically restart when it
has cooled down.
Check for excessive loads or a short circuit on
the inverter output. Correct the problem and
restart by pressing INVERT.
