1. Introduction
The APsystems Energy Communication Unit (ECU-R) is the information gateway for our
microinverters. The unit collects module performance data from each individual
microinverter and transfers this information to an Internet database in real time, requiring
only a single data and power cable. Through the APsystems Energy Monitoring and Analysis
software, the ECU-R gives you precise analysis of each microinverter and module in your
solar installation ECU APP. The user-friendly interface lets you access your solar array in
seconds.
Features
Collects individual module and microinverter statistics
Communicates in real time
Requires no additional wiring
The APsystems ECU-R is used in utility-interactive grid-tied
applications, and is made up of four key elements:
APsystems Microinverter
APsystems Energy Communication Unit (ECU-R)
APsystems APP (ECU APP)
Based on Android and iOS.
APsystems 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 smart phone with ECU 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 (2)
#8 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.

3.4 Cable Connection
1) Using a Wall Mount
Connect the adapter to the power connection port on the top of the ECU-R.
Figure 6
2）Power Distribution Cabinet Installation

Guide rail type socket installation (The guide rail type socket is not supplied
by APsystem).
Connect the adapter to the power connection port on the top of the ECU-R.

3.5 Antenna
Make sure the antenna is properly connected to corresponding position on the
top of the ECU-R.
Connect the antenna to the RF port of the ECU-R,The antenna must be placed
outside the Power Distribution Cabinet.
Figure 8
Do not put the antennas inside a metal box, that will block the signal.

3.6 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 9
Option 2: Wireless Connection.
Use ECU-R internal WLAN (see Managing the WLAN Connection).
