7 Troubleshooting
PROBLEM: AC product will not operate; no inverter
lights are
ON.
PROBLEM: Measured inverter output is too low.
Possible cause Solution
Battery is defective. Check battery and replace if
required.
Loose connections. Check connections.
Possible cause Solution
Standard “average-
reading” AC voltmeter
used to measure output
voltage, resulting in an
apparent reading 5 to 15 V
too low.
Inverter’s “modified sine
wave” output requires “true
RMS” voltmeter for accurate
measurements.
