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.
Wireless or Ethernet network. Only 4G Dongle supplied by APsystems are compatible with our ECU-R. AP button: in case there is need to activate the ECU-R hotspot (see later in the document) Figure 2 APsystems ECU-R Installation/User Manual...
2. Interface Explanation 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.
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. APsystems ECU-R Installation/User Manual...

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. APsystems ECU-R Installation/User Manual...
3. Hardware Installation 3.5 Internet Connection There are two different approaches to connect the ECU-R to the Internet: Option 1: Direct LAN cable connection. Make sure the LAN cable is connected to the network port on the back of the ECU-R.
Make sure you have downloaded the EMA Manager APP on your smartphone or tablet. Make sure the ECU-R hotspot is activated (if not, press the AP button for a few second). Open Settings > Wi-Fi in your smartphone or tablet.
4. ECU-R User Interface 4.2 Enter microinverters UID (serial numbers) into the ECU-R Click “Workspace”, select “ID Management”, input the microinverters UID (serial number: 12 digits starting with a 4, a 5, a 7 or a 8) manually or scan the UID with your smartphone or tablet scanner.
Note: when deleting, please press also “Sync”. Otherwise the microinverter will not be removed from the ECU-R. Once the microinverters UID have been successfully entered into the ECU-R, you need to select grid profile and define the adequate time zone of your ECU. APsystems ECU-R Installation/User Manual...
4. ECU-R User Interface 4.5 Grid Profile From the work space, select “Grid profile”. First select country and then the city. If you select the wrong grid profile, the microinverters may not start or may not produce as per optimal performance.
4. ECU-R User Interface 4.6 Time management From the workspace, please select menu “ECU Date Settings” manual set-up, click “Date”, “Time” and “Timezone” to modify. Automated set-up: Click “Time quick setting”: the APP will synchronise on the time and time zone as per smartphone or tablet settings.
