My AC 200 Max won’t start and screen does not open

My issues are slightly different from the other gentleman that had issues with startup.

Mine will not power on. The power button will remain eliminated for 5 to 7 secs then turn off (nothing else is heard or seen)
I have recently connected a 200w panel replacing the foldable Bluetti panels ( They have packed it in and they have not really been the best)
I’ll keep the other panel connected however how long would you expect the machine to come to life (if it ever does) ?
Is there anything else I can do?
Thanks in advance

It sounds like your AC 200 Max may need a reset or troubleshooting. Try holding the power button longer or check the connections and battery status to see if that helps.

Hi @ZuluStu, We would like to know if your AC200MAX has not been used for an extended period? If so, it’s possible over-discharged.

Additionally, low ambient temperatures might also prevent it from charging or turning on. We suggest placing it in a suitable temperature environment and charging it for a longer period. Does that help? If not, please contact our customer service team for further support.

Thanks to @abuislam for the help and suggestions.
