# Commissioning and Self-Test

## Device Commissioning

Self-Test is the system self-check stage after installation is completed, used to verify whether the electrical topology connections are correct.

### Enter Self-Test

You can enter via the following path:

* The Self-Test prompt page at the end of the installation process
* Device Details → Installation Record → Device Settings → **Self-Test**

### Start Self-Test

1. Tap **Self-Test**.
2. The app first connects to the cloud.
3. A safety warning is displayed after the connection succeeds.
4. Tap **OK** Start the test.

> Self-Test involves high-power charging and discharging. To ensure safety and test accuracy, please keep the load stable. If possible, switch off high-power devices.

### Test Process

* The app automatically switches to landscape mode.
* The page displays the real-time status of the Load, Grid, INV and BAT components and line status.
* The test usually lasts about 2 Mins.
* The label on the right shows the current test step.
* You can tap at any time **Stop** to stop the test.

#### Failure Scenario

If the test detects an error:

1. An error prompt appears at the bottom of the page.
2. The system provides **Re-Start** button.
3. Enter the fault diagnosis process.

The system will first ask you to confirm the metering device type:

* **Meter**
* **CT**

Using `Grid CT Wrong Direction/Position` as an example, troubleshoot in the following order:

1. Reconnect both ends of the communication cable.
2. Check that the Grid\_CT is installed correctly.
3. Check that the Grid\_CT is upstream of the main switch.
4. Check that the arrow points towards the load.
5. If the issue still remains, contact AlphaESS Technical Support.

The bottom of the page provides **Request Technical Support**, allowing you to submit a technical support request with one tap.

After fixing the issue, return to the test page and tap **Re-Start** Retest.
