TECHNICAL INFORMATION
TROUBLESHOOTING GUIDE
ERROR CAUSES - ERROR LED is On or Flashing (look under the ERROR CAUSES display)
INDICATION
OVER CURRENT
Excessive load on the AC output
TRANSFORMER OVERTEMP or
HEATSINK OVERTEMP
Unit is warm/hot to the touch
Let inverter cool down and try
restarting.
HIGH BATTERY VOLTAGE or
LOW BATTERY VOLTAGE
Battery voltage is not within the High or
Low battery cut-out settings.
LOW AC OUTPUT VOLTAGE
The AC output voltage has fallen below
SET INPUT LOWER LIMIT VAC
setting.
AC SOURCE WIRED TO OUTPUT
Indicates that an AC source was wired
directly to the AC output.
GENERATOR START ERROR
Five attempts were made to start the
generator without obtaining the correct
input AC voltage or frequency
GENERATOR SYNC ERROR
Indicates that the generator was
running but was not operating within the
voltage or frequency tolerances and
was not able to connect
GEN MAX RUN TIME ERROR
Indicates that the generator ran for a
period of time that exceeded the 'SET
MAX RUN TIME'
GEN UNDER/OVER SPEED
Indicates that five 'Auto generator start
attempts' have occurred without
successfully starting the generator
Error LED is flashing (no error under
ERROR CAUSES display)
AC source frequency is just out of
tolerance
(53-57 Hz or 63-67 Hz)

Disconnect all wires on the AC input and output.
Reset the inverter by pressing the On/Off switch to OFF, then to SRCH or ON. If
unit comes on, then check AC wire system (shorts or miswired)
Charging: AC input voltage may be too high, check for high input ac voltage
Inverting: operating too large of a load for too long, remove excessive loads
Ambient temperature may be high
Inverter cooling fan may have failed – hold a piece of paper to inverter vents to
check fan, (fan is hard to hear).
Inverter airflow intake may be blocked (small clearance or clogged).
MAX CHARGE AMPS setting needs to be lowered (charging setting is too high
based on ambient temperature around inverter).
Check for the correct battery voltage at the inverter's DC input terminals.
High battery voltage: Ensure your DC source is regulated below your High battery
cut-out or adjust your HIGH BATTERY CUT-OUT to a higher setting
Low battery voltage: Check for an external DC load on the batteries. Check the
condition of batteries and recharge if possible or adjust your LOW BATTERY CUT-
OUT to a lower setting.
The cause for this error could be high battery voltage or an excessively large load.
Check for proper AC input and output wiring (output of inverter is wired to an AC
source)
Reset the auto generator control system by selecting OFF and then AUTO or ON
from the SET GENERATOR menu.
Check the generators output voltage and frequency (ensure that the 'Set Input lower
or upper limit VAC' is set correctly)
This is an advisory ERROR only and will not cause any other effect.
If you continue to have repeated error conditions, then increasing the SET
MAXIMUM RUN TIME menu item setting, under the GEN AUTO SETUP (12) menu
heading, may be necessary for your application.
(a) Voltage has not reached 80 VAC during the 'MAX CRANK PERIOD' or
(b) Voltage did not maintain >80 VAC for the majority of time while the inverter was
charging
No problem with AC source or inverter. The error LED is a visual indicator to fine
tune your AC frequency (this error does not affect operation)
