Event 8708 — Timeout in communication for active power limitation

What does 8708 mean?

The inverter has lost communication with the system control manager (e.g., Sunny Home Manager) responsible for active power limitation. The inverter will either retain the last received values or limit active power to a pre-set percentage.

• Connection to the system manager is interrupted.
• Damaged communication cables between the inverter and system manager.
• Loose or disconnected plugs in the communication line.

Click steps to track your progress.

1. 1

   Ensure the communication connection to the system manager (e.g., Sunny Home Manager) is intact.

2. 2

   Check all communication cables for visible damage.

3. 3

   Verify that all plugs in the communication line are securely inserted.

4. 4

   If communication is still not restored, restart the system manager and then the inverter if possible.
