DC Injection HighDC Injection High

Name in the manufacturer's documentation (user manual): DC Injection High[1]

In plain words (editorial)

The inverter detects too high a DC component in its AC output. The manual says to restart the inverter and check whether the fault still occurs; if not, it was an occasional event.

When to call a service technician: If it keeps occurring, contact your installer or GoodWe after-sales.
