Problem Cause Solution
Measured inverter
output is too low.
Standard “average
reading” AC
voltmeter used to
measure output
voltage, resulting
in an apparent
reading 5V to 15V
too low.
Inverter’s “modified
sine wave” output
requires “true
RMS” voltmeter
for accurate
measurements.
Battery voltage is
too low.
Recharge battery.
Battery run time is
less than expected.
AC product power
consumption is
higher than rated.
Use a larger battery
to make up for
increased power
requirement.
Battery is old or
probably defective.
Replace battery.
Battery is not being
properly charged.
Some chargers
are not able to fully
recharge a battery.
Make sure you use
a powerful charger.
