Disconnect Test

4–3
To monitor the startup sequence on the front panel LCD, check the GT
Inverter LCD. The startup screens (see Table 5-1 on page 5–3) should appear
for five seconds each, and then the “Reconnecting in
sss
seconds” special
screen (see Table 5-11 on page 5–10) will appear until the protection timer
countdown is completed.
7. Run the disconnect test.
Disconnect Test
The disconnect test is designed to verify correct operation of the Xantrex Grid Tie
Solar Inverter both on initial operation and periodically through its life as required
by the utilities. This test ensures that the Xantrex Grid Tie Solar Inverter does not
“island” by sending electricity to the utility grid when the local utility has shut off
the grid for repairs, or when the utility wiring is damaged.
When operation of the inverter has been verified and the unit is producing power,
run the disconnect test as described in this procedure.
To run the disconnect test:
1. Switch off the AC circuit for the inverter.
This can be accomplished by switching the breaker on the main panel that
feeds the inverter(s). The disconnect for the home or business may be used as
well.
2. Have someone watch the front panel of the inverter to ensure the green light
on the front of the inverter goes out.
The green light goes out when the AC circuit is switched off, disconnecting
the inverter from the AC grid. The front panel display will show an AC Fault
display, indicating that the AC is out of the operating range.
3. Switch on the AC circuit for the inverter.
The inverter will respond by beginning its countdown. The green light will
remain off. Following the required delay after applying AC, the green light
will turn on and the inverter will begin to send power to the grid. The display
will then return to showing the power being produced and the total kWh
produced to date.
4. If you have another GT Inverter to commission, switch off the AC circuit for
the inverter you have just commissioned and tested by switching off the
breaker on the main panel. You can then run the commissioning procedure
and disconnect test on the next inverter.
