APsystems Energy Communication Unit ECU-R

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

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)

On the side ECU: from top to bottom are:

• USB port: for reserved.
• AP button: in case there is need to activate the ECU-R hotspot (see later in the document)

Figure 3

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.

NOT I CE

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 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.

2.8 LED1
LED1 will be ON (green light) when the ECU is powered ON
2.9 LED2
LED2 will be ON (green light) when the ECU is exchanging data with the EMA server.
When you haven’t entered microinverters UID into the ECU-R, or The ECU cannot connect to the EMA server, LED2 is OFF.

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.

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.

NOT I CE
The antennas used for ZigBee port and WI-FI port are exactly the same type and are interchangeable.

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.

NOT I CE
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.

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.

Option 2: Wireless Connection.
Use ECU-R internal WLAN (see later in the document, page 15 ).

NOT I CE
ECU-R can communicate with the microinverters up to 76 meters (250 ft) with direct sight.
ECU-R can utilize WiFi (WLAN) up to 9 meters (30 ft) with direct sight.

NOT I CE
4G router is also supported. ECU can be connected to 4G router by wifi or LAN.
