Installation

Installation Options

The GT Inverter may be installed as a single inverter for a single PV array of one or two PV strings, or in a multiple inverter configuration for multiple PV arrays (see Figure 2-1for diagrams of both options).

Single Inverter Installation

In this configuration, a single inverter collects the harvested solar energy and routes the power to the main utility service panel and the utility grid.

Multiple Inverter Installations

If multiple inverters are used, each inverter must be wired to an independent PV array. In this configuration, each inverter collects the harvested solar energy from a separate PV array and routes the power to the main utility service panel and the utility grid.

Communications between inverters is optional, but can be enabled by installing communications cabling to the inverter RJ45 ports. See “Connecting Network Cable between Inverters” on page 3–12.

Planning the Installation

The following issues need to be considered when planning for an installation using the GT Inverter. See the specified sections for more information.

•“Inverter Location” on page 2–4

•“PV Array Requirements” on page 2–5

•“Grounding Requirements” on page 2–7

•“Routing the Wires” on page 2–8.

Ensure that you have obtained all permits required by local authorities or utilities before commencing installation.
