AC200MAX error code 29

Hello…my AC220MAX was switched off for 5 weeks. When I switch it on it shows me error 29. The AC200 is left in cool temperatures for a few hours. Is my power station broken?..what can i de ? …thank you very much…

The manual states error 29 is an “NTC Error”. Googling NTC, it looks this might be a temperature issue. If the “left in cool temperatures for a few hours” was really cold, you might just need to wait for the internals to warm up.


  1. Please confirm that the working temperature is within the range
  2. Turn off the AC200Max and place it in a cool place for two hours and then turn it on again to see if there is an error report. If it still does not work, please contact the support for the repair.
