Application Diagram for Three Phase System

The maximum number of microinverters allowed for each branch depends on the model of the microinverter. And the total number of microinverters of the system is not allowed to exceed the maximum number of microinverter allowed by MECD.

Interface Explanation

Interface position
All of the MECD interfaces as below, from left to right, are Network port, DI, and Power Connection Port.

RS485: This port function is reserved.

DI: Digital input. When the DI status changed from 1 to 0, the MECD will send command to control the microinverter shutdown immediately via Zigbee or PLC.
Power connection port: L1, L2, L3, N, PE, connects power through the power line.
Power cable is included in the MECD package.

Preparation
Make sure you have the following things taken care of before attempting to install the ECD:

• 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 wireless router is available for you to use a laptop.
• With a web browser (to view the EMA online monitoring application).
• A pre-programmed MECD.

Connections

1. Connect the power cable to the power connection port on the bottom of the ECD;
2. Config the wifi device with your home router.

2. Obtain an IP address automatically.
3. Set WiFi connection to the logger

Open wireless network connection and click View
Wireless Networks

Select the wireless network of the logger.
The network name consists of AP and the serial number of the product. Input the password shown on the logger. Then click Connect.

Notice: If AP_(serial number of product) is not available in the wireless network list, there may be problems in the connection or setting of the logger. Please wait several minutes to refresh the list or plug in the logger again.

Set parameters of logger

Open a web browser, and enter 10.10.
100.254, then fill in username and password, both of which are admin as default.
Recommended browsers: Internet Explorer 8+, Google Chrome 15+, Firefox 10+

In the Status page, you can view the general information about the logger.

Follow the setup wizard to start the quick setting.
(a) Click Wizard to start. Select the wireless network you need to connect to, then click Next

Notice: If the signal strength (RSSI) of the selected network is <15%, which means an unstable connection, please adjust the antenna of the router, or use a repeater to enhance the signal.
The SSID of your selected router network should be less than 30 characters, in which blank space should not be included.
(b) Enter the password for the selected network, select Enable to obtain an IP address automatically, then click Next

Notice: Router password cannot be recognized if it contains any character such as’84’, T, T0′, and blank space.
The password is being verified, please wait for a while. If you have entered an invalid password or encryption method, an error notice will pop up.
(c) Enhance the security settings of the WiFi logger by selecting any options as listed, then click Next.
