Why is my Goodwe Inverter showing a Cavity Overtemperature error?
- J
  Jennifer LoveSep 1, 2025
  A 'Cavity Overtemperature' error on your Goodwe Inverter can be due to several reasons: 1. The inverter is installed in a location with poor ventilation. 2. The ambient temperature exceeds 60°C. 3. There is a fault with the internal fan of the inverter. To address this, first, check the ventilation and ambient temperature at the installation point. If ventilation is poor or the temperature is too high, improve ventilation and heat dissipation. If both are normal, contact the dealer or after-sales service.
