This manual is for use by qualified personnel only.
To verify the front panel display:
1. Open then close the AC disconnect and look at the front panel display. It
displays the software versions both of the CCU2 and front panel within the
read menu. Record these numbers.
2. After about 20 seconds the Xantrex GT100 E is in “ready” mode. If any
alarms are present, refer to the Troubleshooting Chapter in your Xantrex
GT100 E 100 kW Grid-Tied Photovoltaic Inverter Operation and Maintenance
Manual (Part # 152365).
3. Once all faults are clear, the front panel should report “Switched Off” and
show Inverter Status.
4. Using the \/ key, scroll down in the read menu and verify that the time and
date are correct.
5. If the time and date are not correct, refer to the Xantrex GT100 E 100 kW
Grid-Tied Photovoltaic Inverter Operation and Maintenance Manual (Part #
152365).
6. Scroll thorough the parameters and verify that they are present.
To confirm AC operational parameters:
1. For each of the following steps, refer to front panel display.
1. Access the write menu parameter list by pressing <MENU>. Using the \/ key,
scroll down in the write menu and verify the parameter settings.
2. Verify the inverter’s AC limits.
3. Make any necessary changes.
4. Record these values.
To confirm DC operational parameters:
1. Verify the inverter’s PV settings.
2. Make any necessary changes.
3. Record these values.
To confirm power tracker configuration operational parameters:
1. Verify the inverter’s power tracker configuration.
2. Make any necessary changes.
3. Record these values.
To verify inverter operation:
1. Make sure all doors are closed and locked.
2. Using the front panel user interface or the PV View GUI, set the I PPT Max
percent to 10%.
3. Place the
ON/OFF switch in the ON position. If the PV voltage is above PV start
voltage threshold, followed by a 5-minute delay period, the PV contactors
(K2) closes, followed by the main AC contactor (K1). The inverter begins to
produce power up to 10% of rated power.
4. Look, listen and smell for any defects.
5. Make sure the internal enclosure fans are operating.
6. If everything is okay, increase the I PPT Max until you reach 100%.
