4. TROUBLESHOOTING

1. Basic Troubleshooting

The ME Series inverter/ charger is a fairly simple device to troubleshoot. There

are only two active circuits (AC and DC) as well as a charging circuit. The

following chart is designed to help you quickly pinpoint the most common inverter

failures.

WARNING: De -energize all sources of power including batteries (DC), shore power (AC), and AC

generator (as applicable).

Symptom Possible Cause Recommended Solution

No output power.

Inverter LED is OFF.

Inverter is switched OFF.

Battery voltage is too low.

Switch the in verter ON.

Check battery voltage, fuses,

breakers and cable connections.

No output power.

Inverter LED is OFF.

High or low battery voltage. Check the battery voltage at

the inverter's terminals.

Discharge or charge batteries.

Replace the batteries.

No output power.

Green LED is flashing.

Load is too small for search

mode circuit detection.

Reduce the search threshold

or defeat search mode.

Low output power. Low batteries. Check and recharge batteries.

Appliances turn OFF/ON.

Green LED is flashing.

Loose or corroded battery cables.

Low batteries.

Loose AC output connections.

Clean and tighten all cables.

Recharge or replace batteries.

Tighten AC output connections.

AC output voltage seems

too low when using a meter.

Wrong type of voltmeter used

(displays 80 VAC to 100 VAC).

Use a “true” RMS voltmeter.

Low surge power. Low batteries.

Battery cables are the

wrong length or gauge.

Check and recharge batteries.

Verify recommended cable lengths

and gauges from the manual.

Replace cables as necessary.

Low charging rate

when connected to

shore power.

Charge rate set too low.

Low AC voltage (< 90 VAC).

Adjust charge rate from remote.

Check AC input wiring.

Low charging rate

when using a generator.

Generator output is too low

to power both load and charger.

Reduce the load.

Increase the generator’s RPMs.

Charger doesn’t charge. Loose or corroded battery cables.

Defective batteries.

Wrong charger settings.

Wrong AC input voltage.

Clean and tighten battery cables.

Replace batteries.

Adjust the charger settings.

Verify proper AC input

voltage and frequency.
