Troubleshooting

Low AC power output
or low surge power.
INVERT LED is on.
AC inductive loads are
not running at full speed.
Insufficient DC current being provided
to the inverter to operate the AC loads.
Check the battery voltage, fuses or breakers
and cable connections.
Ensure the battery bank is sufficient (check
for low DC voltage while running the load).
Ensure the cable length and size is correct
(see Installation Guide for correct cable). Tie
the battery cables together to reduce
inductance.
Inverter turns on and
then off or doesn’t turn
on at all.
Search Watts setting is too low or high.
Potential problem loads for Search
Mode:
•
Incandescent lights
have a higher
starting wattage when the filament is
cold than the continuous rating of the
bulb.
•
Fluorescent bulbs
work the opposite
of incandescent light bulbs. If the
inverter is set to detect a 30-watt load
and a 40-watt fluorescent is switched
on, the inverter will not detect it,
This is because the fluorescent tube
is less than 30 watts until the gas in
the tube ionizes.
•
Other loads:
Some appliances draw
power even when turned off: TVs
with instant-on circuits, microwaves
with digital clocks, VCRs, and
clocks.
If the search sensitivity is set higher than the
combined loads, then an auxiliary load must
be used to bring the inverter out of Search
Mode before the appliances can be turned on.
If the sensitivity is set lower than the
combination of the loads, the loads will
remain on and excess battery drain will occur
since the inverter won’t ever “idle.”
One solution is to turn the item off at the
wall, use an extension cord with a rocker
switch, a switch at the outlet, or an
appropriate circuit breaker.
