AC module overtemperature

Was bedeutet 304 ?

This code indicates that the AC module within the inverter has reached an excessively high temperature. This causes a short-term interruption in energy feeding, after which the inverter will resume its startup routine once temperatures normalize.

• Restricted airflow to the inverter's cooling system due to blocked vents or dirty heat sinks.
• High ambient temperatures, or direct sunlight exposure on the inverter enclosure.
• Failure of internal cooling fans on the AC side.
