APsystems ECU-3 V4 Installation/User Manual

Introduction

The APsystems Communicator, our state-of-the-art Energy

Communication Unit (ECU), 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 Monitor software, the

APsystems Communicator gives you precise analysis of each

microinverter and module in your solar installation from any

web-connected device. The APsystems Communicator’s integrated

http webserver 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

Communicates in real time

Requires no additional wiring

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)

APsystems Energy Monitor and Analysis (EMA)

web-based monitoring and analysis system

Interface Explanation

Interface Position

All of the ECU interface as below, from left to right, are power

connection port, serial port, network port, USB interface and reset.

Power Connection Port RS232 Serial port Network port USB interface Reset

Figure 2

Power Connection Port

Power connection port connects power through the power line.

Figure 3

RS232 Serial Port

You can connect GPRS module to RS232 serial port, select GPRS

module to connect to the network on “Network Connectivity” page,

and communicate with the EMA, to check the system data.

Figure 4

Interface Explanation

Network Port

RJ45 Ethernet network port: ECU allows user to communicate

with EMA, or log in ECU's local page in the case of the absence

of the wired LAN and WLAN, set up the system and view the

system data via Ethernet network port.

USB Interface

USB interface is reserved.

Reset

Press the “Reset” button for three seconds or longer, ECU will

automatically return to the default settings.

NOTE: The historical power generation won't be cleared.

Hardware Installation

Preparation

Make sure you have the following things taken care of before

attempting to install the ECU:

A dedicated standard AC electrical outlet (located

electrically as close to the array as is possible).

A broadband Internet connection is available for your

use.

A broadband router with either a CAT5 Ethernet, or

wireless router is available for your use.

A laptop with a web browser (to view the APsystems

EMA online monitoring application).

A pre-programmed ECU.

Selecting an Installation Location for the ECU

A location that is electrically as close to the array as

is possible-preferably a dedicated outlet installed

directly to the solar system sub-panel.

The ECU is NOT rated for outdoor use, so if installing

outdoors near a junction box or breaker panel, making

sure that you enclose it in an appropriate weather proof

NEMA electrical box.

1) Using Electrical Mounting Din Rail

Loosen the two (2) M3 mounting screws on the back of

the ECU and rotate the two (2) rail holders so that the

holders are above the ECU.

Hardware Instrallation

Attach the ECU to the mounting rail with machine screws.

Figure 6

2) Using Wall Mount

When mounting the ECU to a wall, make sure to select a

cool, dry, indoor location.

Depending on the wall surface you are mounting the

ECU to, use either two (2) #8 drywall screws or wall

anchors, installed 130 mm apart. The drywall screws

and wall anchors are NOT included in the ECU kit.

Align and slide the ECU onto the mounting screws.

Figure 7

Best Practice: Install and connect the ECU to the Internet

(see below instructions) while the rest of the array is being

installed. Doing so allows the ECU to automatically update

its internal software while the rest of the physical installation

is underway. The ECU will then communicate with the inverters

when the installation is complete and the array is energized.

Cable Connections

Power Connection Port Network port

Figure 8

Connect the supplied power cable to the power

connection port on the bottom of the ECU.

Connect the supplied LAN cable to the network

port on the bottom of the ECU.

Internet Connection

There are three different approaches to connecting the ECU

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.

2) Connect the LAN cable into a spare port on the

broadband router.

Figure 9

Option 2: Wireless Connection.

Use ECU internal WLAN (see Managing the WLAN

connection pg. 25).

Hardware Installation

Option 3: Using a PLC bridge:

1) Make sure the LAN cable is connected to the network

port on the bottom of the ECU.

2) Connect the LAN cable into the “send” unit of the PLC

bridge.

3) Connect a LAN cable from the “receive” unit of the PLC

bridge into a spare port on the broadband router (refer

to bridge users manual for specific operating instructions).

Figure 10

NOTE: The network cable in the package could be used for

the users to connect the ECU with PC directly. One side is

connected with the ECU and the other side is connected with

the PC. Then change the IP address and the network mask

into 192.168.131.1 and 255.255.255.0 respectively.

NOTE: 1. A PLC bridge uses the power line to communicate

and requires both a “send” and “receive” unit.

2. The quality and length of LAN cable will affect

the ECU communication quality. You can use a Switch to

enhance the communication quality if necessary.

Hardware Installation

Power Up ECU

Make sure the power cable is correctly connected to the

power connection port on the bottom of the ECU.

Plug the power cable into a dedicated standard AC

electrical outlet.

WARNING: Make sure to use a dedicated outlet for the

ECU. Do NOT plug any other devices into the same outlet

as the ECU.

Figure 11

WARNING: Do NOT plug the ECU into a power strip,

surge protector, or uninterruptable power supply (UPS).

The surge suppression and/or filtering on these sorts

of devices will substantially diminish PLC performance.
