Keep the cables between the battery and the power inverter as short as
possible and twist them together with about two to three twists per foot. This
minimizes radiated interference from the cables.
7.2 Troubleshooting Guide
Problem and
Symptoms
Possible
Cause
Solution
No output voltage,
no voltage
indication.
Inverter
switched off.
No power to
inverter
Turn inverter ON. Check wiring to inverter.
Internal fuse
open
Have qualified service technician check and
replace.
Reverse DC
polarity
Have qualified service technician check and
replace fuse, OBSERVE CORRECT
POLARITY.
No output voltage,
Over Voltage
indicator on
High input
voltage
Make sure that inverter is connected to 12 V
or 24 V battery. Check regulation of
charging system.
Low battery alarm
on all the time.
Poor DC
wiring, poor
battery
condition.
Use proper cable and make solid
connections. Use new battery. Reduce load.
No output voltage
and Under Voltage
indicator on
Low input
voltage
Recharge battery, check connections and
cable.
No output voltage,
Over Temp
indicator on, load
in excess of:
1500 W:
150 A (12V) or 75
A (24 V)
Thermal
shutdown
Allow inverter to cool off. Reduce load if
continuous operation required.
No output voltage,
Over Temp
indicator on, load
less than:
1500 W:
150 A (12 V) or 75
A (24 V)
Thermal
shutdown
Improve ventilation, make sure ventilation
openings in inverter are not obstructed, and
reduce ambient temperature.
No output voltage,
Over Load
indicator on.
Short circuit
or wiring
error.
Check AC wiring for short circuit or improper
polarity (hot and neutral reversed).
