Quick Tips

Normal Displays that should not cause any worry:

BUL = Battery is in bulk charge

ABS = Battery is in absorbtion charge

FUL = Battery is full

Component

Problem

Source of Problem

Solution

Heavy Duty & Standard Power Packages

(1000 and 1800 watts)

Error Code: E01 

Inverting Mode

Low battery voltage shutdown depending on setting

Check battery status and recharge if necessary.

Check for proper DC cable sizing.

Check for loose connections and tighten if necessary.

 

Error Code: E02

Inverting Mode

 

High battery voltage shutdown >15.5 volts DC

 

Check for external charging sources, such as an over voltage alternator, and disconnect if necessary.

 

Error Code: E03

Inverting Mode

AC output overload shutdown

Reduce the loads connected to the AC outlet of the unit.

Check equipment that have high-surge ratings and disconnect if necessary.

 

Error Code: E04

Inverting Mode

 

Over-temperature shutdown

Reduce the loads connected to the AC outlet of the unit.

Check that the ventilation grille is not blocked.

Check for ambiet temperature and move the unit to a cooler location whenever possible. 

 

Error Code: E05

Inverting Mode

Low battery voltage detected (depending on setting)

Check battery status and recharge if necessary.

Check for proper DC cable sizing.

Check for loose connections and tighten if necessary.

 

Error Code: E06

AC output overload warning

Reduce the loads connected to the AC outlest of the unit.

 

Error Code: E07

Inverting Mode

Over-temperature warning

Reduce the loads connected to the AC outlet of the unit.

Check that the ventilation grille is not blocked.

Check for ambiet temperature and moce the unit to a cooler location whenever possible.

 

Error Code: E10

AC Shore Power Mode

High battery voltage (>15.5 V)

Check for external charging sources, such as an over voltage alternator, and disconnect if necessary.

Confirm that the external charging source is not the cause.  The error may be caused by the internal battery charger systems.  Call for support.

 

Error Code: E11

AC Shore Power Mode

Over-temperature detected on the AC transfer relay

Reduce the loads connected to the AC outlet of the unit.

Check that the ventilation grille is not blocked.

Check for ambient temperature and move the unit to a cooler location whenever possible.

 

Error Code: E12

AC Shore Power Mode

Battery is bad or external DC load is connected to the battery.

Check the battery bank. NOTE: The battery voltage did not rise above 5 volts DC after 1 minute or 10 volts DC after 15 minutes.

Check that external DC load current consumption is below the charging current setting.

Disconnect the DC load or increase the charger current setting.

 

Battery charging current is lower than the charging set point during bulk charge mode.

Ambient (environment) temperature is high.

Do not be alarmed, the unit is performing normally. The charging current automatically de-rates at high ambient temperatures. Improve ventilation. Make sure the unit's ventilation openings are not blocked.

 

Alarm does not sound when an error is encountered.

Alarm is turned OFF.

Press and hold the Select button for two seconds to disable (or enable) the audible alarm.
 

Low output voltage (96-104 volts AC) during Inverter mode.

You are using a voltmeter that cannot accurately read the RMS voltage of a modified sine wave.

 Use a true RMS reading voltmeter such as a Fluke 87.

 

No output voltage. The status LED is red.

AC shore power is not available or out of operating range and the inverter has shut down with the display screen shoing one of the following codes:

 

 

"   "

Low input voltage (fault code E01)

Check the DC connections and the cable. Recharge the battery.

 

"   "

High input voltage (fault code E02)

Verify the unit is connected to a 12V battery.

Check the voltage regulation of the external charging system (if any).

 

 "   "

Unit overload or AC output short circuit (fault code E03)

Reduce the load. Make sure the load does not exceed the output rating.

 

 "   "

Thermal shutdown (fault code E04)

Allow the unit to cool off.

Reduce the load if continuous operation is required.

Improve ventilation. Make sure the inverter's ventilation openings are not blocked.

 

 "   "

AC transfer relay has overheated (during short power mode)

Improve ventilation. Make sure the inverter's ventilation grille is not blocked.

Reduce the load.

 

No output voltage. The Status LED is green or yellow.

GFCI has tripped or 15A supplementary breaker has tripped.

Check the load and reset the GFCI or supplementary breaker.

 

 "   "

 
Circuit breaker on the AC load panel or AC output disconnect has tripped.

Check AC shore power. Turn the inverter ON.

 

  "   "

Battery voltage is too low to start inverting. Display screen may show DC voltage as 00.0

Check DC connections and cable. Recharge the battery.

 

No output voltage. The Status LED is not lighting up.

AC shore power is not available or out of operating range and the inverter is OFF.

Check AC shore power. Turn the inverter ON.

 

  "   "

AC shore power is not available and the inverter is OFF due to a shutdown for more than 30 seconds.

Check AC shore power and the battery voltage.

Turn the inverter ON and look at the display panel for any error code.

 

  "   "

The inverter's DC input polarity is reversed.

The inverter was probably damaged due to the reverse polarity. This type of damage is NOT covered by warranty.

 

The fan turns on and off during AC shore power mode.

The battery is discharged and demands high current from the charger.

AC pass-through current is high.

Do not be alarmed, the unit is performing normally.

 

The fan turns on and off during inverter mode.

The inverter is running continuously at high power.

Do not be alarmed, the unit is performing normally. The fan is activated automatically.

 

Battery is swollen and not charging.

Battery is discharged and has reached life end.

Replace with new battery.

 

No display on remote meter.

Phone like cord is not tight.

Plug cord in tightly on remote and inverter side.
