Brand new Bluetti Elite 300.
Using as UPS (250 Watts in/out for my PC).
This unit has a very annoying fan rattle even at this low level the fan runs 100% of the time.
It is like a constant fast ticking sound. Why Bluetti continues to use substandard fans I cannot imagine. This seems to be the chief complaint with these units.
What’s my recourse here? I don’t want to ship the unit in directly after I have received it? If I do not have my headphones on, it is hard to sit and work because of the annoying noise.
This is because all the reviewers who shill Bluetti power stations are just paid to highlight the good points and aren’t real world testers of the products. The only time Bluetti finds out about these types of issues is actual real world use. Most reviews are all the same. Here’s what I like. Here’s what I don’t like. Here’s what they can improve. They don’t actually long term test the products, find out the fan is annoying, and report on that. With that said, I wouldn’t be surprised at all if this was a design decision by Bluetti to save pennies. Their newer PV350 is absolute garbage compared to Gen 1 PV350, producing 20% less power in the same Sun. I think your best solution may simply be to place the unit farther away from you.
Hi @dredge999 it would be really helpful if you could post a video of the noise issue,Bluetti would want you to do this anyway when they are trouble shooting your problem. Also is all your firmware up to date? @BLUETTI_CARE could you help please.
