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.
Fault
Description
Code
The AC line voltage has dropped below its minimum threshold. It
is normal to see this when the inverter has been disconnected
2280
from the grid. It may also occur momentarily when large
equipment is turned on nearby.
Indicates that there is a problem with one or more of the turbine
input phases. The inverter shuts down to protect the turbine from
2500
potential damage. Check for bad connection(s), blown fuse and
ground faults on the turbine side.
Grid output current on line 1 has exceeded its maximum current
3000
threshold. This can be caused by a sudden grid load change.
Grid output current on line 2 has exceeded its maximum current
3020
threshold. This can be caused by a sudden grid load change.
The DC Boost circuit has exceeded its maximum current
3050
threshold. Check for ground faults on the turbine side.
The internal high temperature threshold has been exceeded.
Check for obstructions in the intake (bottom) and exhaust vents
4000
(both sides), cooling fans are both working, proper ventilation is
provided and no exposure to direct sunlight.
The internal low temperature threshold has been exceeded.
4250
Avoid exposing the unit to temperatures below -20ºC (-68ºF).
A grid side phase is shorted to chassis ground. It may require a a
7000
Megger to troubleshoot the fault.
The frequency of the utility grid voltage went out of range. This
8000 can occur when large equipment is switched on/off, if the grid is
disconnected or the grid flickers.
The frequency of the utility grid voltage went out of range. This
8100 can occur when large equipment is switched on/off, if the grid is
disconnected or the grid flickers.
