APsystems ECU-R Installation/User Manual

1. Introduction

The APsystems Energy Communication Unit (ECU-R) is the information

gateway for our microinverters. The ECU-R collects module performance

data from each individual microinverter and transfers the information to an

Internet database in real time. Through the APsystems Energy Monitoring

and Analysis (EMA) software, the ECU-R gives you precise analysis of each

microinverter and PV module in your solar installation powered by

APsystems. The user-friendly interface gives you access to your solar array

performance in seconds from our web based portal or from our APP.

Features

Collects individual PV module and microinverter statistics

Communicates in real time

Requires no additional wiring

The APsystems ECU-R is used in utility-interactive grid-tied applications,

typically consisting of five key elements:

APsystems microinverter(s)

APsystems Energy Communication Unit (ECU-R)

EMA Manager APP: for installer to set-up the ECU-R

EMA APP: to enable end-users to have access to the data and

performance of their system anytime, anywhere

APsystems Energy Monitoring and Analysis (EMA): web-based

monitoring and analysis system, for both end-users and installers

2. Interface Explanation

2.1 Interface Layout

The ECU-R interface includes, (figure 2) from left to right

Reset button

Wifi antenna connector (WLAN communication between ECU and

router)

power connection port

RJ45 Signal port (for Australia only)

RJ45 ethernet network port (LAN communication between ECU and

router)

Zigbee antenna connector (communication between ECU and

microinverters)

Reset Antenna (WIFI) RJ45 ethernet network port Antenna (ZigBee)

On the side ECU: from top to bottom are:

USB port (North America ONLY): for cellular communication using an

external 4G dongle. It is recommended to only use the cellular

communication in areas where there is no easy access to Wireless or

Ethernet network. Only 4G Dongle supplied by APsystems are

compatible with our ECU-R.

AP button: in case there is need to activate the ECU-R hotspot (see

later in the document)

2. Interface Explanation

2.2 Reset

Press the Reset button for a minimum of three seconds: the ECU-R will

automatically return to the default settings.

2.3 Power Connection Port

The power connection port connects power through the power adapter.

2.4 RJ45 Ethernet Network Port

The ECU-R allows the user to communicate with the EMA server via

Ethernet cable.

2.5 RJ45 Signal (Only for Australia)

The RJ45 Signal is designed for DRM0, it should be connected by RJ45

connector in the package otherwise the inverter will not work.

Please do not plug out the RJ45.

2.6 Antenna

The antennas supplied with the ECU-R must be connected to the ECU-R.

One antenna is used for the communication between ECU-R and

microinverters (Zigbee signal), the other antenna is used for the Wi-Fi

connection between ECU-R and router.

2.7 USB port

North America ONLY: for cellular communication using an external 4G

dongle. It is recommended to only use the cellular communication in areas

where there is no easy access to Wireless or Ethernet network. Only 4G

Dongle supplied by APsystems are compatible with our ECU-R.

2.8 AP

The AP button enables to turn on the ECU wifi hotspot. When setting up the

ECU, installer needs to first connect to the ECU hotspot via his smart phone

or tablet.

Press the AP button for a few seconds: the ECU hotspot will be live for one

hour. If more time is needed to set-up the ECU, press the AP button to

reactivate the hotspot.

3. Hardware Installation

3.1 Preparation

Make sure you have the following components ready before

beginning the installation of the ECU-R:

A standard AC electrical outlet (located as close as possible of the

PV array to ensure good communication between ECU and

microinverters).

A broadband Internet connection available for your use.

A broadband router with either a CAT5 Ethernet, or a wireless

router.

A smartphone or tablet with EMA Manager APP ready to use (see

page 11).

3.2 Selecting an Installation Location for the ECU-R

Choose a location that is as close as possible of the PV array.

The ECU-R is NOT rated for outdoor use. If installing outdoor,

ensure that the ECU-R is put in a waterproof box, and that the

antenna (wifi and Zigee) are placed outside of the box to ensure

optimum communication. In case you need to use extension

antennas to be closer to the PV array, please make sure the

extension antennas are Wifi 2.4GHz with SMA connectors

male/female. These extension antennas are not supplied by

APsystems, but can be purchased at any electrical/PV shop.

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.

Figure 4

3. Hardware Installation

2) if the HECU-R is not mounted on a wall mount, you can put it anywhere

on a flat surface or furniture, close to a power outlet.

3.4 Cable Connection

1) ECU-R outside of a cabinet (wall mounted or not)

Connect the adapter to the power connection port at the back of

the ECU-R.

Figure 5

The antennas used for ZigBee port and WI-FI port are exactly the same

type and are interchangeable.

APsystems ECU-R Installation/User Manual

3. Hardware Instrallation

2）Installation inside a power cabinet

Install the socket on the guide rail (The socket is not be supplied by

APsystems).

Connect the adapter to the power connection port at the back of

the ECU-R.

Figure 6

ECU antennas must be left outside of the cabinet, even if the cabinet is

made of plastic. Please make sure the extension antennas are Wifi

2.4GHz with SMA connectors male/female. These extension antennas

are not supplied by APsystems, but can be purchased at any

electrical/PV shop.

APsystems ECU-R Installation/User Manual

3. Hardware Installation

3.5 Internet Connection

There are two different approaches to connect 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

back of the ECU-R.

2) Connect the LAN cable to a spare port on the broadband router.

See more info later in the document.

Figure 7

Option 2: Wireless Connection.

Use ECU-R internal WLAN (see later in the document, page 15 ).
