Diagnostic Procedures using Power Inverter Error Codes
Two types of codes are displayed on the power inverter, Shutdown and Warning.
•
Shutdown error codes will shut the power inverter off.
•
Warning error codes will appear on the display panel to alert of an impending system change. See important note
below.

Condition
Diagnostic Procedures
Shutdown
Inverter has no power, no status
lights
1.
Confirm DC disconnect switch is in the ON position
2.
Confirm power inverter’s power switch is turned ON
3.
Check 150 Amp fuse inside charger enclosure
4.
Check 20 Amp fuse inside charger enclosure
5.
Check 150 Amp fuse near lift gate battery
6.
Check for loose or poor battery connections
7.
Inspect battery cables and wires for abrasions and damage
8.
Use voltmeter to check voltage reading at lift gate battery
E01
Shutdown
Low battery voltage <10.2VDC
Inverter’s display screen will turn off after 30 seconds. After three seconds it will
immediately stop inverting.
1. Check lift gate battery voltage and recharge to greater than 12.6V to clear code.
2. Check for loose or poor lift gate battery connections and tighten as necessary.
E02
Shutdown
High battery voltage >15.75VDC.
Note: The unit will stop inverting.
1. Check voltage regulation of the external charging system of lift gate battery, i.e.,
alternator.
E03
Shutdown
AC output overload
Note: The unit will stop inverting.
1. Verify load is less than 2000 watts.
2. Reduce AC load verify if code clears.
3. Restart inverter.
E04
Shutdown
Over temperature
Note:
NOTE: Inverter will automatically resume operation once inverter’s internal
temperature returns within the normal operating range.
1. Reduce load(s) connected to the GFCI outlet.
2. Check ventilation grille of inverter is not blocked.
3. Move EPJ to cooler location if possible.
4. Turn inverter off for 15 minutes, then restart.
E05
Warning
Low battery voltage detected.
See modes below for details.
Modes:
1. Check lift gate battery voltage and recharge to appropriate voltage based on setting.
2. Check for loose or poor LG battery connections and tighten as necessary.
P01/P02
<12.2 VDC, > 10.2VDC and AC
output will last for one minute.
P03/P04
<12.5 VDC, > 10.2VDC and AC
output will last for three minutes.
E06
Warning
AC output overload warning
1. Reduce load connected to GFCI receptacle.
E07
Warning
Over temperature
1. Reduce load connected to GFCI receptacle.
2. Check ventilation grille of inverter is not blocked.
3. Move EPJ to cooler location if possible.
