1. Introduction
The APsystems Energy Communication Unit (ECU-B) is the information
gateway for our inverters.ECU-B has been specially developed to monitor
small PV systems up to 4 PV modules.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 APsystems Energy Monitoring and Analysis software, the
ECU-B 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 PV module and microinverter statistics
Communicates in real time
Requires no additional wiring
The APsystems ECU-B is used in utility-interactive grid-tied applications,
typically consisting of five key elements:
APsystems microinverter(s)
APsystems Energy Communication Unit (ECU-B)
EMA Manager APP: for installer to set-up the ECU-B
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
2.2 Reset
Press the Reset button for three seconds or longer, and the ECU-B will
automatically return to the default settings.
The wireless password will be changed to “88888888”.
Interface Explanat
2.3 Power Connection Port
The power connection port connects power through the power adapter.
2.4 Antenna
The antennas in the package should be connected to ECU-B. One antenna is
used for the communication between ECU-B and inverters, the other
antenna is used for the Wi-Fi connection between ECU-B and router.
2.5 USB port
The USB interface is reserved.
2.6 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 to install the ECU-B:
A dedicated standard AC electrical outlet (located as close as
possible of the PV array to ensure good communication between
ECU and microinverters).
A wireless router.
A smartphone or tablet with EMA Manager APP ready to use (see
page 10).
3.2 Selecting an Installation Location for the ECU-B
Choose a location that is as close as possible of the PV array.
The ECU-B is NOT rated for outdoor use. If installing outdoor,
ensure that the ECU-B 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-B to a wall, make sure to select a cool, dry
indoor location.
Depending on the wall surface you are mounting the ECU-B 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-B
kit).
Align and slide the ECU-B onto the mounting screws.

2) if the ECU-B is not mounted on a wall mont, you can put it anywhere on
a flat surface or furniture, close to a power outlet.
3.4 Cable Connection
1) Using a Wall Mount
Connect the adapter to the power connection port on the top of the
ECU-B.
The antennas used for Zigbee port and WI-FI port are exactly the same
type, no need to distinguish.

3. Hardware Instrallation
2）Power Distribution Cabinet Installation
Install the socket on the guide rail (The socket will not be supplied
by APsystems Please prepare it yourself).
Connect the adapter to the power connection port on the top of the
ECU-B.
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
Use ECU-B internal WLAN (see Manage the WLAN connection ).
