General Introduction for the i-Energy GT260 i-Micro inverter System

i-Energy GT260 is designed with high transform efficiency, DC(PV panel) to AC(Grid)

i-Micro inverter. Each i-Micro inverter is individually paired with a PV panel, which

ensures each PV panel has its own MPPT, and can individually export AC power to grid

utility. A recommended PV module should have 240W to 265W power output, to

ensure that GT260 i-Micro inverter can work with the best MPPT efficiency.

GT260 i-Micro inverter is a certificated, fully outdoor design with IP 65 protection level,

it is recommended to mount the inverter near your PV panel with its rack. Aside from

this manual, see www.i-energyinc.com/downloads for further support.

The complete i-Energy i-Micro inverter system should be with i-Manager, a web based

PLC communication data login to monitor your i-Micro inverter system.

i-Micro inverter Installation Manual

This specification defines the GT260 for 240W to 265W solar panels. The i-Micro

inverter is designed to be plugged between the solar panel and the power grid, and

converts DC power into AC power.

Copy Right @ i-Energy Corp 2013

The i-Micro inverter is used to quickly and easily connect the PV module to transfer

source energy from the DC to AC circuit, then connect to the electrical utility grid or to

energize the AC circuit.

GT 260 Installation Procedures

Things to check before installing GT260:

Please have your technician or installers to review the following items listed below

before beginning the installation.

Item

Check items

Read through the i-Micro inverter input/output specifications and warning

items.

Type of roof material qualified to install PV systems

Broadband connection is established/connected

Available Ethernet socket

Sufficient grid utility point

Anyone who installs or replaces the i-Micro inverter must be an

authorized and licensed personnel, who can ensure the safety

practice of a qualified assembly, installation or replacement.

Do not disassemble the inverter’s casing to prevent risks of electric

shock and fire.

Select a suitable PV panel with a short circuit current less than 12

Amp.

For i-Micro inverter installation to the rack and PV module, follow the key steps below:

Step 1- affix the i-Micro inverters serial number to the ” i-Energy System Mapping

Guide” found in the i-Manager box.

Copy Right @ i-Energy Corp 2013

Step 2- Attach the i-Micro inverter to the rack before connecting it to the PV module.

Step 3- Connect the AC cables to each branch of the PV module system.

Step 4- Connect the grounding system.

Step 5- Connect the DC cables to each PV module.

Step 6- Use the cable accessory to connect between the AC cables of i-Micro inverter

and the AC source.

Step 7- When all of the installation steps have been completed, it is now safe

to turn on the AC source to begin operation.

Step1-- Affix the i-Micro inverters Serial Number to the” i-Energy System Mapping

Guide” Found in the i-Manager Box.

Take i-Micro inverter out of its box, and turn it over to find its serial number.

a. Remove serial number sticker located directly below GT260 i-Micro inverter label.

b. Affix serial Number sticker to the “i-Energy System Mapping Guide”

Fig. 1. Turn over i-Micro inverter to see serial number

System Mapping Guide

Please go to www.i-energyinc.com to download the “i-Energy System Mapping Guide” if

you don’t have an i-Manager, or if an additional “i-Energy System Mapping Guide”is

needed.

Step 2 --Attach i-Energy i-Micro inverters to the Rack

a. Take i-Micro inverter out of the box, mount i-Micro inverter onto the rack.

Install mounting hardware.

Copy Right @ i-Energy Corp 2013

b. Use a M8 or M10mm size screw to fix the inverter.

c. The gap distance between the roof surface and the back of the PV modules needs to

be at least 1cm.

Fig. 2.2 The necessary gap for the i-Micro inverter’s back side.

Recommended racking specifications can be found at www.i-energyinc.com, by

downloading the “System racking guide”.

Step 3- Connecting to the Grounding System.

a. Use a recommended grounding lug with a continuous ground wire, see Fig. 3.1.

b. Grounding washers ( i.e. Wiley Electronics “ WEEB”). Suggested torque

requirement is 18.5 N-m Minimum.

Inverters must be grounded according to related local standard.

The lay-in lug from ILSCO (P/N: GBL-4DBT) or other certified

products of equivalent or better quality can also be used.

Step 4- Connecting the i-Micro inverters AC Cable to the PV Module System.

a. Connect adjacent i-Micro inverters to each other through AC interconnection

cables.

b. Listen for a click as connectors engage.

Make sure any unused i-Micro inverter AC connector is covered with a sealing end

cap. Do not exceed 17 pcs of i-Micro inverters connected per branch.
