Disconnect the inverter
and wipe immediately
with a dry cloth, or
permanent damage can
occur with liquid ingress.
Standard “average-reading”
AC voltmeter used to
measure output voltage,
resulting in an apparent
reading 5 to 15V too low.
Inverter’s “modified sine
wave” output requires “
true RMS” voltmeter for
accurate measurements.
Measured
inverter
output is too low
Battery voltage is too low.
Battery run time
is less than
expected
Recharge battery.
AC product power
consumption is higher
than rated.
Battery is old or properly
defective.
Battery is not being properly
charged.
Use a larger battery to
make up for increased
power requirement.
Replace battery.
Some chargers are not
able to fully recharge a
