Installation
2–2 975-0466-01-01
Installation Options
The GT Inverter may be installed as a single inverter for a single PV array of up to
two PV strings (up to three PV strings for the GT5.0-AU model), or in a multiple
inverter configuration for multiple PV arrays (see Figure 2-1 for 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 3–14.
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.
