In plain words (editorial)
The inverter's output current has too high a DC component (above the limit set by safety regulations or the default). If an external fault caused it, the inverter resumes normal operation on its own once the fault is gone.
When to call a service technician: If it occurs frequently and affects power generation, contact your installer or GoodWe after-sales.
