ERROR CAUSES - ERROR LED is On or Flashing (look under the ERROR CAUSES display)

INDICATION

SOLUTION

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)
