Name in the manufacturer's documentation (user manual): Cabinet Overtemperature
[1]
In plain words (editorial)
The inverter cabinet is too hot. The manual names a poorly ventilated installation location, too high ambient temperature, or an abnormal internal fan, and says to improve ventilation and heat dissipation.
When to call a service technician: If ventilation and ambient temperature are normal, contact your installer or GoodWe after-sales.
