Problem Cause Solution
Inverter runs
small loads
but not large
loads.
Low voltage battery. Charge the battery.
Water entered. Water entered the unit. Disconnect the inverter and
wipe immediately with a dry
cloth, or permanent damage
can occur from the liquid.
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 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.
Power dissipation in DC
cables.
Use shorter/heavier DC
cables.
