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 Digital
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.
