Xantrex Technology 400 W, 800 W, 200 W manual Problem Measured inverter output is too low

Page 33

Problem: Measured inverter output is too low.

Possible Cause

Solution

Astandard “average-reading” AC voltmeter has been used to measure output voltage, resulting in an apparent reading 5–15 V too low.

The battery voltage is too low.

For accurate measurement, the Digital Inverter modified sine wave output requires a “true RMS” voltmeter for accurate measurements.

Recharge the battery.

Problem: Battery run time is less than expected.

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.

The battery is not being charged properly.

Replace the battery.

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.
