Routing the Wires

Typical

Determine all wire routes to and from the GT Inverter. Typical routing

configurations

configurations include:

 

• AC wiring from the GT Inverter to the main utility service panel

 

• DC input wiring from the PV array to the GT Inverter

 

• DC ground from the PV array to the Primary Earth Ground.

 

All wiring and installation methods should conform to applicable electrical and

 

building codes.

 

For installations in the United States, the National Electrical Code (NEC) and

 

local codes apply. For installations in Canada, the Canadian Electrical Code

 

(CEC) and local codes apply.

 

For all installations, local utilities may have additional requirements.
