8.7 Inverter Faults:
While the batteries are being discharged in the Inverter Mode, the system will
continuously check for faults as part of its diagnostic capabilities.
LED2 (Inverter LED)
will illuminate red
and will blink a specific quantity which correlates to the fault type.
Listed below are the fault types and the blink quantities associated with each of the
fault types. To clear the fault, press the system test button after problem was
diagnosed/repaired which initiates a new system start-up.
OVER TEMPERATURE (LED2
–
1 Blink)
Indicates that the MOS
FET’s Heatsink temperature has exceeded its limits. This fault will clear itself
after it cools down so no reset is required.

| INSTALLATION / OPERATION MANUAL
AC FUSE (LED1
–
3 Blinks)
Indicates the AC fuse has blown. Check for overloads and wiring errors and replace fuse.
CHARGER/INVERTER (LED1
–
4 Blinks)
Indicates that there is a fault with the Charger/Inverter module.
VOLTAGE SELECT JUMPER (LED2
–
2 Blinks)
Indicates that the VOLTAGE SELECT JUMPER is not inserted. Insert jumper to the correct location so
that the Incoming AC voltage matches the VOLTAGE SELECT JUMPER location.
BACKFEED (LED2
–
3 Blinks)
Indicates that there is AC voltage already at the output terminals back-feeding into it. This fault
means that the E3MINI Series was wired incorrectly between the output terminal and the load.
Since this fault was already checked at power up, it is possible that there is a remote transfer
device which is back-feeding during Inverter operation.
OVERLOAD (LED2
–
4 Blinks)
Indicates that there is too much load connected or there is a short circuit. Check the connected
load wiring and/or reduce the connected lo
ad to the power of the inverter’s rating.
INVERTER (LED2
–
5 Blinks)
Indicates that there is fault with the Inverter module.
LVD (LED2
–
6 Blinks)
Indicates that the inverter ran on battery until the Low Voltage Disconnect (LVD) point. This fault
will only be present for 1 minute and then the system will turn itself off.
