ESS Relay test Pending — Feed-in disabled until test completes

What does ESS Relay test Pending mean?

The system is in the process of performing a required relay test before it can begin feeding power from the battery or solar to loads or the grid. During this test, the system needs to run in inverter mode.

• The system has just been connected or restarted, and the relay test is initiated.
• Battery voltage is too low to complete the relay test.
• The ESS Assistant is installed and requires this initial test.

Click steps to track your progress.

1. 1

   Ensure the battery has sufficient charge (e.g., above 14/28/56 volts or 20% SOC).

2. 2

   Allow the system time to complete the test, which typically takes about 1 minute.

3. 3

   Check the 'ESS Relay test' status in the Multi/Quattro's Advanced submenu on the device list. It should change from 'Pending' to 'Completed'.

4. 4

   If the test repeatedly fails, check battery health and connections.
