Problem: Measured inverter output is too low.
Problem: Battery run time is less than expected.
Possible Cause
Solution
A standard “average-reading”
AC voltmeter has been used to
measure output voltage,
resulting in an apparent reading
5–15 V too low.
For accurate measurement, the Inverter
modified sine wave output requires a “true
RMS” voltmeter for accurate measurements.
The battery voltage is too low.
Recharge the battery.
Possible Cause
Solution
The AC product power
consumption is higher than
rated.
Use a larger battery to make up for the
increased power requirement.
The battery is old or defective.
Replace the battery.
The battery is not being charged
properly.
Some chargers are not able to fully recharge
a battery. Make sure that you use a powerful
charger.
Power dissipation in DC cables. Use shorter/heavier DC cables.
