Operate Inverter
To operate the inverter:
1. Make sure all transformer and inverter assembly doors are closed and
locked.
2. Energize PV input to the Xantrex GT500. PV voltage must be above the
starting voltage for the Xantrex GT500 to proceed.
3. Using the front panel or the GUI, set the
I PPT Max percent to 10%.
4. Place the
ENABLE/DISABLE switch in the ENABLE position. If the PV voltage is
above the PV Start voltage threshold, after a 5-minute delay period the DC
switch S1 will close, followed by the AC circuit breaker CB1. The inverter will
begin to produce power up to 10% of rated power.
5. Listen for sounds of arcing, loud 60 Hz humming, or popping noises within
the Xantrex GT500. If these sounds are heard, quickly de-energize the AC
grid and PV input at the external disconnecting means, and then follow the
“Lock-out and Tag-out Procedure” on page xi and contact customer service.
6. Make sure you can hear the internal enclosure fans operating.
7. If everything is okay, increase the
I PPT Max in 5% increments until you
reach 100%.
8. Check all the operating data with the GUI or front panel. Record any
irregularities.
9. Let the inverter run to continue with commissioning.
10. Complete “Step 11. Operate the Xantrex GT500 in Power Tracking Mode” on
page C–4 on the form in Appendix C.
CAUTION
HAZARD OF EQUIPMENT DAMAGE
Do not manually press the PUSH TO ON button on the CB1 breaker to
energize AC to the Xantrex GT500. Perform a controlled energization of AC
using the ENABLE/DISABLE switch.
Failure to follow these instructions can result in equipment damage.
