Starting the Inverter
Commissioning Procedure
To ensure that each GT Inverter is wired correctly, each inverter should be wired individually using the wiring procedures in Chapter 3, and turned on using this commissioning procedure. Once a single inverter has been commissioned, it should be turned off and the wiring and commissioning procedures should be performed for the next inverter. Repeat in this manner until all the inverters in the installation have been connected.
Perform this commissioning procedure
CAUTION: Equipment damage
Improper wiring may cause permanent damage to the GT Inverter. Take special care to ensure the positive (+) and negative
WARNING: Shock hazard
Hazardous voltages are present from two sources. Use extreme caution during startup procedure. Before applying power to the GT Inverter, ensure all AC and DC wiring is correct.
WARNING: Shock hazard
Ensure the protective earth (ground) wire from the inverter is connected to Earth before applying AC. Failure to do so could result in a shock hazard upon touching the enclosure. Consult the local utility for specific grounding requirements.
To start the GT Inverter:1.Ensure the AC breaker is off.
2.Ensure the correct
3.Ensure the AC quick connect is firmly inserted into the AC connector on the GT Inverter and the coupling ring is tight.
4.Uncover the PV array and/or close the main DC disconnect switch, if one is installed.
Ensure the PV array is producing the required output voltage.
5.Connect the utility grid voltage by switching the AC circuit breaker on.
6.Monitor the startup sequence on the front panel LCD.
The GT Inverter starts automatically when it receives DC voltage within the correct range and it is connected to an acceptable grid.
