Important Safety Instructions
Symbols replace words on the equipment, on a display, or in
manuals
Trademark.
Caution, risk of electric shock.
Equipment protected throughout by double insulation or
reinforced insulation
CE mark is attached to the solar inverter to verify that the unit
follows the provisions of the European Low Voltage and EMC
Directives.
Qualified
personnel
Person adequately advised or supervised by an electrically
skilled person to enable him or her to perceive risks and to avoid
hazards which electricity can create. For the purpose of the
safety information of this manual, a "qualified person" is
someone who is familiar with requirements for safety,
refrigeration system and EMC and is authorized to energize,
ground, and tag equipment, systems, and circuits in accordance
with established safety procedures. The inverter and endues
system may only be commissioned and operated by qualified
personnel.

1.Introduction
The APsystems Energy Communication Unit (ECU-C) 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. Through the APsystems Energy Monitoring and Analysis software, the
ECU-C gives you precise analysis of each microinverter and module in your solar
installation from any web-connected device. The ECU-C’s integrated http web
server offers the simplest and most flexible network integration of any data logger
on the market. The user-friendly browser-based interface lets you access your solar
array in seconds.
Features
Collects individual module and microinverter statistics
Remote communication
Requires no additional wiring
Applicable commercial system
The APsystems Microinverter is used in utility-interactive grid-tied applications,
and is made up of three key elements:
APsystems Microinverter
APsystems Energy Communication Unit (ECU-C)
APsystems Energy Monitoring and Analysis (EMA) web-based
monitoring and analysis system

2.Interface Explanation
2.1 AC Input Port
The AC Input port connects power through the power line.If only single-phase
power is needed, the L1 must be connected.

The AC input power should be assembled with disconnector(e.g. when the
current is bigger than 1A, the disconnector should be operated).
2.2 DC Input Port
The DC Input port connects power through the 16V DC power line.
2.3 RJ45 Ethernet Network Port
The ECU-C allows the user to communicate with the EMA, or log in to the
ECU-C's local page in the absence of the wired LAN and WLAN, to set up the
system and view the system data via Ethernet network port.
Ethernet cable connection is recommended for stable communication.
2.4 RJ45 Signal（Only for Australia）
The RJ45 Signal is designed for DRM0/5/6/7/8, it should be connected by RJ45
connector in the package otherwise the inverters will not work.
Please do not plug out the RJ45.

2.Interface Explanation
2.5 AP
Press the AP button to turn on AP. Then the ECU can be scanned by phone. You
can press the button again to turn off AP. If you don't turn off AP, ECU will turn
off it automatically in one hour.
2.6 Power
Press the button, ECU will be powered on. Press the button again, the button
would bounce back and ECU will be powered off.
2.7 USB Interface
The USB interface is reserved.
2.8 Reset
Press the Reset button for three seconds or longer, and the ECU-C will
automatically return to the default settings.
The historical power generation won't be cleared.
2.9 LED
The OK light will blink when ECU-C starts up, and it will keep on after
registering.
The Comm light will be on when the ECU-C connects to EMA.
The Fault light will be on when the ECU-C breaks down.

3.Hardware Installation
3.1 Preparation
Make sure you have the following components ready before beginning to install
the ECU-C:
A broadband Internet connection available for your use.
A broadband router with either a CAT5 Ethernet, or a wireless router .
A laptop with a web browser (to view the APsystems EMA online
monitoring application).
A pre-programmed ECU-C.
3.2 Selecting an Installation Location for the ECU-C
Choose a location that is electrically as close to the array as possible.
The ECU-C 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.
Avoid to install in the place children can not touch.
1) Power Distribution Cabinet Installation
If you use the energy communicator in power distribution cabinet:
Pull the four snap out with a screwdriver.

3.Hardware Instrallation
Attach two buckles below in the edge of the guide, press two buckles
above, then embed to the edge of the guide.
Figure 7
Do not put the antennas inside a metal box, that will block the signal.
If the roof is metal, please use this long cable antenna, and place it outside
or on roof.
2) Using a Wall Mount
When mounting the ECU-C to a wall, make sure to select a cool, dry indoor
location.
According to the size of an icon, The energy communicator is fixed on the
wall with two Wall screws or wall anchors.
Four M4 screws + spacers are fixed to the wall, and the punch sizes are
as follows:

Connect the power cable to the power connection port on the top of the
ECU-C.(Can also be DC power supply).
Connect the supplied LAN cable to the network port on the bottom of the
ECU-C.
3.4 RJ45 Signal connection
Plug the RJ45 connector in the package to RJ45 Signal port.
3.5 Internet Connection
There are three different approaches to connecting the ECU-C 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-C.
2) Connect the LAN cable to a spare port on the broadband router.
