Table 6-1

Troubleshooting the GT Inverter

Problem

Possible Cause

Solution

The inverter’s LEDs and display are
blank and the inverter does not
operate in sufficient sunlight.

Utility service panel AC and DC
breakers are switched off.

Turn on the breakers in the sequence
described in “Commissioning
Procedure” on page 4–2.

The display reads

Inverter Offline

and

AC Voltage Fault

Utility service panel breakers are
switched off.

AC grid voltage is not present or
incorrect.

Turn on utility panel breakers.

Check AC connections at the
inverter’s terminals. Ensure AC
voltage within the range specified in
“Output” on page A–2 is present.

The display reads

Inverter Offline

with sufficient sunlight.

DC breakers are switched off (if
installed), or DC fuses are blown (if
installed).

DC array voltage is not present.

Turn on any DC breakers and check
any DC fuses.

Check DC connections at the
inverter’s positive and negative DC
terminals. Check for incorrectly
wired PV arrays.

The display reads

Inverter Offline

and

DC Voltage Fault

with sufficient

sunlight.

DC voltage is present but incorrect.

Check DC connections at the
inverter’s positive and negative DC
terminals. Check for incorrectly
wired PV arrays. Ensure a voltage
within the operating voltage range is
present at the inverter’s terminals.

Only the inverter RED LED is
illuminated and the display reads

Ground Fault

Ground fault condition detected on
the PV array.

The PV system should be checked
by a qualified electrician and
repaired. See “PV Ground Fault
Detection” on page viii. To
reconnect:
1.

Make sure the GT Inverter is not
outputting power, and then
switch off the DC breaker. If a
DC breaker is not used, then
disconnect the DC input.

Switch off the AC breaker.

Remedy the actual ground fault.

Restart the unit using the
sequence described in
“Commissioning Procedure” on
page 4–2.
