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 Table 5-9 on page 5–8.
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.
2. Switch off the AC breaker.
3. Remedy the actual ground fault.
4. Restart the unit using the
sequence described in
“Commissioning Procedure” on
page 4–2.
The
System
value (power being
produced by the system) displayed
on each inverter’s LCD is different
on inverters connected to the same
daisy-chained network.
Inverters can display different
System
values when one of the
inverters is set to a different baud
rate than the rest. That particular
inverter's baud rate screen shows Tx
and/or Rx error (see Table 5-4 on
page 5–6).
Check each inverter’s baud rate and
compare the settings. Change any
inverters with an incorrect baud rate.
Make sure to follow the
recommended procedure supplied by
Xantrex. See the Application Note,
Xantrex Grid Tie Solar Inverter
Baud Rate Change Procedure
(976-0216-01-01 available on
www.xantrex.com).
