1. Introduction
The Energy Communication Unit (ECU-R) is the information gateway for our inverters. The
unit collects module performance data from each individual inverter and transfers this
information to an Internet database in real time, requiring only a single data and power
cable. Through the Energy Monitoring and Analysis software, the ECU-R gives you precise
analysis of each inverter and module in your solar installation from APP. The user-friendly
interface lets you access your solar array in seconds.
Features
Collects individual module and inverter statistics
Communicates in real time
Requires no additional wiring
The ECU-R is used in utility-interactive grid-tied
applications, and is made up of four key elements:
Inverter
Energy Communication Unit (ECU-R)
APP (ECU APP)
Based on android and iOS.
Energy Monitoring and Analysis (EMA)
Web-based monitoring and analysis system.

3. Hardware Installation
3.1 Preparation
Make sure you have the following components ready before
beginning to install the ECU-R:
A dedicated standard AC electrical outlet (located
as close to the array as is possible).
A broadband Internet connection available for your use.
A broadband router with either a CAT5 Ethernet, or a wireless router.
A phone with APP (see page 10).
3.2 Selecting an Installation Location for the ECU-R
Choose a location that is as close to the array as possible
The ECU-R is NOT rated for outdoor use, so if installing outdoors near a junction
box or breaker panel, make sure you enclose it in an appropriate weatherproof
NEMA electrical box.
3.3 Installation
1) Using a Wall Mount
When mounting the ECU-R to a wall, make sure to select a cool, dry indoor location.
Depending on the wall surface you are mounting the ECU-R to, use either two
drywall screws or wall anchors, installed 100 mm apart (The drywall screws
and wall anchors are not included in the ECU-R kit).
Align and slide the ECU-R onto the mounting screws.

2）Power Distribution Cabinet Installation
If you use the energy communicator in power distribution cabinet:
Install the 2 guide rail fasteners on the Guide rail, the space between fasteners
shall be 100mm.
Align and move the ECU-R to the 2 guide rail fasteners.

3.5 Internet Connection
There are two different approaches to connecting the ECU-R
to the Internet:
Option 1: Direct LAN cable connection.
1) Make sure the LAN cable is connected to the network
port on the bottom of the ECU-R.
2) Connect the LAN cable to a spare port on the
broadband router.
Figure 7
Option 2: Wireless Connection.
Use ECU-R internal WLAN (see Managing the WLAN Connection).
