To wire the main utility service panel to the GT Inverter:

1. Install conduit from the main utility service panel to the wiring/disconnect

box of the GT Inverter. Run the two HOT wires (L1 and L2) and ground wire

from the service panel through the conduit and into the inverter wiring box.

2. Install or use an existing double-pole 20-Amp circuit breaker (or two

single-pole breakers, ganged) in the main utility service panel, and ensure that

the breakers are set to OFF.

3. Connect the ground wire (green or bare copper) from the ground bar in the

main utility service panel to the GND bar in the wiring box.

4. Connect the L1 HOT wire (black) from the double-pole breaker installed in

the main utility service panel, to the L1 GRID terminal in the wiring box.

5. Connect the L2 HOT wire (red) from the double-pole breaker installed in the

main utility service panel, to the L2 GRID terminal in the wiring box.
