and no LED’s
Battery voltage at the inverter's
terminals is too high or low
Battery over discharge protection
circuit set too high
Load too small for Search Mode
circuit to detect
ComPort Accessories are improperly
installed
Check the battery condition
Lower cutout voltage an/or battery bank
size setting
Reduce search threshold setting or defeat
the Search Mode
Re-install or remove options from the
ComPort

AC input voltage does not match
inverter Spec
Charger controls improperly set
Check AC input for proper voltage and
frequency of your model
Refer to Owners Manual for proper setting
of battery charger parameters
Low charge rate
Low peak AC input voltage (164
volts peak required for full charger
output)
AC current too small to handle load
Use larger generator, speed up generator,
check AC input wiring size, adjust charge
rate, cable too small or too long
Reduce charge amps setting and/or shed
pass through loads
Low AC output
voltage
Measuring with the wrong type
voltmeter
Voltmeter must be a true RMS reading
meter (most are not)
Low surge power
Weak batteries, battery cables too
small or too long
Refer to cable and battery
recommendations in owner's manual
