The fan on the AC180 is running all the time and is too loud to have in a room or tent/camper.
Bluetti support have not been able to give me an answer. I am guessing it must be normal operation.
I would not purchase it again for inside use.
The fan runs based on incoming or outgoing load as well as high temperatures. It should not be running all the time as you state. Is it indeed running all the time or are certain incoming or outgoing loads occurring or warm temps exp. immediately after charging.
Hi did you get a solution to this as my fan does exactly the same rather annoying when i am working in my office and all it is doing is running a TV
Hi, myAC180 didn’t start out with a noisey fan. I had a fault code come up and then it was running all the time and got noisey. after a while my charge rate lost its mind and it wasn’t charging properly as well. I think I just got the lemon. Bluetti went through some faults with me and accepted that there was a problem and changed it over. The service was very good. The fan still runs when there is different loads but it is now more of a background noise rather than a disturbing noise. It is not something that you would have in the tent with you while camping as it might get annoying. I have the AC200L as well and it is a bit more expensive but a better unit for less noise. Overall the Bluetti is a great product.I hope this helps
