Frequency Fault
47.0Hz
The actual frequency is over or under the allowable range, as
specified in “Output” on page A–2. This is a utility fault; it
will clear itself when the frequency comes within the
specified range.†
Over Temp Fault
81.4C 178.5F
The unit’s internal temperature is greater than 80° C, the unit
will shut down automatically and only restart when the
temperature has dropped to less than 70° C.
Ground Fault
Reset System
A grounding fault is detected. The ground fault protection
fuse will be blown (North American models only). The
system must be shut down completely, the fault corrected,
and the fuse replaced.‡ The system can then be restarted.
Troubleshooting a grounding fault should be performed by
qualified personnel.
Unit Shutdown
via Remote
The GT Inverter unit has been shut down via a computer
connected to the RS-232 port.
Protection uP
Not Responding
The protection processor is not responding.
* It is normal to receive this fault during low light conditions at dawn or dusk. At
such times, the PV voltage drops below the lower limit of the maximum power
point range, and the array does not have sufficient energy to power the inverter.
† Grid fault. When this fault is cleared the protection timer will begin its
countdown and you will see the “Reconnecting in sss seconds” and “Inverter
Offline” special screens (see Table 5-11) flashing alternately until the
countdown is complete.
‡ Applicable to North American models only. European models do not have a
ground fault protection fuse installed.
