Step 1: Download APP.

Scan the QR code in the manual to download the SolaXCloud App.

Step 2: Register an account and log in.

Open the app and follow the prompts to register a new account or log in with existing credentials.

Step 3: Add a site.

In the SolaXCloud app, navigate to add a new site. Enter the required information such as System Size, Country and region, Timezone, and Position. Agree to the terms and click Next.

Step 4: Bind ECC in the added site.

Select the ECC device to add. Ensure the AP hotspot status light on the ECC is on. If not, turn on the AP hotspot according to the diagram in the app. Click “already open ECC hotspot” and then “Next”. Scan the QR code on the device or enter the registration number manually.

Step 5: Configure network for ECC.

Once the device is found, the app will ask to connect to the device’s Wi-Fi. Go to your phone’s Wi-Fi settings and connect to the network named like “WIFI_XXXXXXX”. Return to the app. The app will then ask you to select your home 2.4Ghz Wi-Fi network and enter the password. The app will then proceed through several connection steps: Device hotspot connection, Device communication detection, Connect the device to the router, and Device registration in the cloud. Once successful, click “Finish”.

NOTICE: After ECC configuration succeeds, the connected ECC-PLC will show on the Gateway list. Remember to switch your phone back to your home WiFi for subsequent operation.

Step 7: Bind A1-Micro devices.

Enter the Device Detail interface for the ECC. Click “Manage sub devices” and then “Collecting sub devices” to bind the A1-Micro 1 in 1 devices. The sub-devices will appear in the list.

Step 8 & 9: Check data and graphics.

After binding, click on “Chart” from the Device Details screen to see more detailed information. From the Chart screen, you can see total devices and their status. You can click “Expand” on a specific microinverter to check its live data and performance graphics, such as Power(W), Voltage(V), Current(A), and Temperature(°C).
