Connecting the AC Wiring
The GT Inverter can be connected to a single bi-directional meter, or to dual
meters, where one meter indicates power used and the second meter indicates
power sold (power supplied back to the utility). Consult the local utility to
determine the proper components to install, and obtain any permits required prior
to installation.
Making AC Connections for the GT2.8-AU Model
GT Inverter model 2.8-AU is equipped with a quick connect for making AC
connections. You must install a mating connector on the the wiring between the
utility panel and the GT Inverter. The GT Inverter must be connected to the utility
with three wires—two lines (one Active phase and one neutral phase) and one
protective earth (ground). Wiring must meet all code requirements and be a
minimum of 2.5 mm
2
. The recommended Binder connector will accept cables
with an outside diameter of 10-12 mm and a maximum 2.5 mm
2
wire size.
You will need:
• Wire strippers
• Small (3 mm) slot-head screwdriver
• Binder, Series 693, Female Cable Connector, Part Number 99-4222-14-04
The AC wiring from the utility panel must be terminated with a Binder Female
cable connector (Binder Series 693 part number 99-4222-14-04) before being
connected to the AC quick connect on the GT Inverter.
To terminate the AC wiring:
1. Strip 10 mm of insulation from each of the wires from the utility panel.
2. Unscrew the female terminal from the shell of the female cable connector. See
Figure 3-5.
3. Unscrew the other components of the female cable connector.
4. Run the wires through the pressing screw, pinch ring, seal, and shell of the
female cable connector.
5. On the female terminal, connect the protective earth wire to the terminal
marked with the symbol. See Figure 3-6.
6. Connect the neutral conductor to the terminal marked with 1.
WARNING: Shock hazard
Before wiring the AC connections between the GT Inverter and the AC breaker panel,
ensure the
main breaker in the breaker panel is switched OFF, and that PV power is
disconnected from the inverter. Do not reapply AC or PV power until after all wiring is
completed, as part of the commissioning procedure in Chapter 4, “Starting the Inverter”.
