Fault Mode

Fault Mode causes
5–8
When a fault state is detected, the appropriate fault message appears on the front
panel display at the next screen refresh (within 2 seconds). The GT Inverter fault
message screens are shown in Table 5-8. The numbers used in Table 5-8 are
examples of what may display when a fault is present.
These message screens only appear when there is a fault, and then flash
alternately with the Inverter Offline default screen (Table 5-5) until the fault is
corrected.

Appears When...
The actual DC voltage is over or under the allowable range.
Self-clearing, no action required.
The PV array should be configured such that DC voltage
falls within the input voltage maximum power point range as
specified for your model in "Electrical Specifications" on
page A–2.*
The actual AC voltage is over or under the allowable range,
as specified in "Electrical Specifications" on page A–2.
This is a utility fault; it will clear itself when the AC voltage
comes within the specified range.† If the fault does not clear,
a phase-to-neutral line may not be connected properly.
0.5 A less than the maximum output fault current. See
"Electrical Specifications" on page A–2. The message clears
after 15 seconds if the output current falls below the limit.
The actual frequency is over or under the allowable range, as
specified in "Electrical Specifications" on page A–2. This is
a utility fault; it will clear itself when the frequency comes
within the specified range.†
The unit's internal temperature is greater than 80° C
(176° F), the unit will shut down automatically and only
restart when the temperature has dropped to less than 70° C
(158° F).
A grounding fault is detected. The ground fault fuse will be
blown. The system must be shut down completely, the fault
corrected, the fuse replaced (see "Replacing the Ground
Fault Protection Fuse" on page 6–4) and then the system
restarted. Troubleshooting a grounding fault should be
performed by qualified personnel, such as a certified
electrician or technician.
The GT Inverter unit has been shut down via a computer
connected to the RS-232 port.
