WARNING: De -energize all sources of power including batteries ( D C ) , shore power ( A C ) , and AC
generator (as applicable).
Symptom Possible Cause Recommended Solution
No output power.
Inverter LED is OFF. Inverter is switched OFF.
Battery voltage is too low.
Switch the in verter ON.
Check battery voltage, fuses,
breakers and cable connections.
No output power.
Inverter LED is OFF. High or low battery voltage. Check the battery voltage at
the inverter's terminals.
Discharge or charge batteries.
Replace the batteries.
No output power.
Green LED is flashing. Load is too small for search
mode circuit detection. Reduce the search threshold
or defeat search mode.
Low output power. Low batteries. Check and recharge batteries.
Appliances turn OFF/ON.
Green LED is flashing. Loose or corroded battery cables.
Low batteries.
Loose AC output connections.
Clean and tighten all cables.
Recharge or replace batteries.
Tighten AC output connections.
AC output voltage seems
too low when using a meter. Wrong type of voltmeter used
( d i s p l a y s 80 VAC to 100 VAC). Use a “true” RMS voltmeter.
Low surge power. Low batteries.
Battery cables are the
wrong length or gauge.
Check and recharge batteries.
Verify recommended cable lengths
and gauges from the manual.
Replace cables as necessary.
Low charging rate
when connected to
shore power. Charge rate set too low.
Low AC voltage (< 90 VAC).
Adjust charge rate from remote.
Check AC input wiring.
Low charging rate
when using a generator. Generator output is too low
to power both load and charger. Reduce the load.
Increase the generator’s RPMs.
Charger doesn’t charge. Loose or corroded battery cables.
Defective batteries.
Wrong charger settings.
Wrong AC input voltage.
Clean and tighten battery cables.
Replace batteries.
Adjust the charger settings.
Ve rify proper AC input
voltage and frequency.
