Troubleshooting Guide

Symptoms
No power output and no
warning LEDs
No power output and
LED indicator is flashing
No power output and
warning LEDs "ON"
Power output is low and
inverter turns loads on
and off
Inverter clicks every 20
seconds
Charger is inoperative or
Overload LED is "ON"
Overload LED "ON"
while charging
Low charge rate
Low AC output voltage
Low surge power
AC Lights flicker while
charging
Xantrex RV Series Inverter/Charger Owner's Manual
Problem
Battery voltage at the inverter's
terminals is too high or low
Load too small for Search Mode
circuit to detect
High or Low battery LED "ON"
Overload LED is "ON"
High temp LED is "ON"
Low battery
Loose or corroded battery
connections
Loose AC output connections
Output of inverter wired back to its
own input
AC input voltage does not
match inverter spec
Charger controls improperly
set
Charger circuit may be damaged
Low peak AC input
voltage(164 volts peak
required for full charger output)
AC current output of generator
too small to handle load
Measuring with the wrong type
voltmeter (displays 80–100 VAC)
Weak batteries, battery cables too
small or too long
Generator is unstable—charger is
losing synchronization
Remedy
Check the battery voltage, fuses
or breakers and cable
connections
Reduce search threshold setting
or defeat search mode
Check the battery voltage at
the inverter's terminals
Remove loads from the
inverter and restart
Remove loads and let
inverter cool down before
restarting
Check condition of batteries
and recharge if possible
Check and clean all
connections
Check all AC output
connections
Check for proper AC input and
output wiring
Check AC input for proper
voltage and frequency of
your model
Refer to owner's manual for
proper setting
Have inverter serviced
Use larger generator, speed
up generator, check AC
input wiring size, adjust
charge rate, cable too small
or too long
Reduce charge amps
setting or reduce pass-
through loads
Voltmeter must be a true RMS
reading meter (most are not)
Refer to cable and battery
recommendations in owner's
manual
Turn battery charger rate down
until problem is gone
