Troubleshooting
Problem Cause Solution
Unit does not
operate
Input voltage is
below 10 volts
Attach to proper supply
Fuse blown Determine cause for fuse blowing
and then replace fuse feeding
inverter.
Over voltage Check DC input voltage
Unit operates
for a short
period and then
turns off
Load is trying to
draw too much
current
Be sure load is less than rated watts
of inverter. Remove excessive
load. Turn inverter off and back on
to reset.
Unit operates
for a while and
gets warm
Inverter is in
thermal shutdown
mode
Allow inverter to cool down. Turn

Output voltage
reads
incorrectly
Modified sine
wave output can
cause incorrect
reading on a
typical multimeter
Use a true RMS meter like a Fluke
8060A or Triplett 4200 to measure
correct voltage.
