Fault Message
Fault
Code
Description
AC UNDER VOLT
2280
The AC line voltage has dropped below its minimum threshold. It
is normal to see this when the inverter has been disconnected
from the grid. It may also occur momentarily when large
equipment is turned on nearby.
TURBINE PHASE
2500
Indicates that there is a problem with one or more of the turbine
input phases. The inverter shuts down to protect the turbine from
potential damage. Check for bad connection(s), blown fuse and
ground faults on the turbine side.
AC OVER
CURRENT
3000
Grid output current on line 1 has exceeded its maximum current
threshold. This can be caused by a sudden grid load change.
AC OVER
CURRENT
3020
Grid output current on line 2 has exceeded its maximum current
threshold. This can be caused by a sudden grid load change.
DC OVER
CURRENT
3050
The DC Boost circuit has exceeded its maximum current
threshold. Check for ground faults on the turbine side.
OVER TEMP
4000
The internal high temperature threshold has been exceeded.
Check for obstructions in the intake (bottom) and exhaust vents
(both sides), cooling fans are both working, proper ventilation is
provided and no exposure to direct sunlight.
UNDER TEMP
4250
The internal low temperature threshold has been exceeded.
Avoid exposing the unit to temperatures below -20ºC (-68ºF).
GROUND FAULT
7000
A grid side phase is shorted to chassis ground. It may require a a
Megger to troubleshoot the fault.
AC OVER FREQ
8000
The frequency of the utility grid voltage went out of range. This
can occur when large equipment is switched on/off, if the grid is
disconnected or the grid flickers.
AC UNDER FREQ
8100
The frequency of the utility grid voltage went out of range. This
can occur when large equipment is switched on/off, if the grid is
disconnected or the grid flickers.
8. Equipment Maintenance
Periodically check the ventilation screen for the cooling fans. When necessary, use a vacuum to
clean the screen from the outside of the enclosure. Do not force air or spray water into the
enclosure.
The touch screen display may become dirty over time. To clean the display use clean water
applied to a soft non-abrasive cloth. Water sprayed directly onto the display could possibly leak
inside and cause damage. Dirt and fingerprints do not affect the operation of the touch screen
display.
