AC180P TEMP flashing cannot charge

Product Discussion BLUETTI Apex & AC Series
1

Bluetti AC180P TEMP flashes upon turn on, and when I try to charge it – either solar, grid or car charger – and does not charge.

App shows Error Error 074, BMS System fault.

I bought this unit in Nov 2023 and used it infrequently on vacation and road trips with no issues, until March 2025.

This started in March 2025, Bluetti support told me to discharge to 0% then recharge, this worked, but this month (July 2025) the issue came back, this time looks like it is intermittent – sometimes I turn it on and no TEMP flash, I can charge laptop etc., but still cannot charge the unit.

Currently I can charge my laptop, (no TEMP flash) but I cannot charge the unit (TEMP flashes when I connect solar, Car or grid),

Bluetti support diagnostic is “low ambient temp” but I am in 85+ degree weather. They are jerking me off with late responses to emails, and all kind of weird requests. Finally they opened a warranty ticket, but it seems I will have to pay for the shipping.

I am asking your opinion. I see quite a few complaints about this same issue on the internet. Is Bluetti messed up ? Should I switch to another company — if so, which ?

Your time and responses highly appreciated.

Hi @Avery05, We take your feedback very seriously and are more than willing to assist you.

We have tried to look up your service records, and finally found that the customer with service ticket number #314996 has the same situation as you. Could you please confirm if this is your ticket?

We have conducted an investigation into the service process and found that the entire service experience was indeed cumbersome. You had to deal with different phone customer service representatives, so sometimes you needed to repeat the problem, which indeed caused inconvenience to you.

We have decided to arrange an upgraded service for you, including a follow-up visit, simplifying the process, and sending a carton. Please rest assured that we will bear all the costs. Please be assured that we will take responsibility for your order and continue to follow up on this matter.

So this is how this Bluetti Customer Support (does not) work:

BLUETTI_CARE sends you an email telling you everything is going to be okay, they take your complaint seriously, and they ‘upgraded’ your request for a quick resolution.

If you try to ‘reply’ to this email, it goes to a no-reply… type of email, so nobody reads it. Probably an AI automated response to make you believe they are on it … So, nothing is being done.

Now, (I think fake) agents send you e-mails: customer support agent X here, I got you, this is being worked as we speak — type of thing. If you ‘reply’ to that e-mail, it goes to a generic inbox at [service@bluetti.com] ---- NOT to an e-mail personalized to that customer service agent. Next “agent”, or the AI, that picks up you e-mail probably has no idea what’s going on — proof of that is that they typically don’t include the e-mail trail that describes your problem. So no, you are NOT dealing with a personalized customer service. Maybe not even with a human being, AI probably sends you cookie cutter e-mails to soothe you.

Absolutely horrible experience. This last “agent” who contacted me said they sent me a FedEx package box to ship my unit for repair under warranty — he gave me the FedEx tracking #. After 3 days of tracking not showing any activity, I contacted FedEx and they told me that the shipper DID NOT GIVE THE PACKAGE TO FEDEX !!! SO nothing is coming, nothing is being shipped.

This is after over 2 weeks of back and forth e-mails (with 2+ days response time), and mikey-mouse ‘diagostics’ that basically point back to user error. If you call Customer service, they keep apologizing and say that everything will be okay, but really nothing happens.

Bluetti should understand that the most money a company makes, and the most customer loyalty a company gets, is from Customer Support, NOT only from your products. If a product is mediocre, but customer service is top, people would keep buying that product, because they know if any issues arise, there is somebody — a human being — at the end of the line (or e-mail message) that will take care of them quickly and efficiently.

By the way, if you google “Bluetti TEMP flashing there a a LOT of people having this issue (and worse issues), even with newly bought units. Quality assurance and checks, and proper unit testing doesn’t seem to be on Bluetti’s plan. New (or new-ish) units having major issues, and with a horrible customer service. What a scam !!

All sweet talk and no action.

Got a few emails from Bluetti support agents telling me not to worry and that they will solve this quickly. They arranged to send me a carton (I don’t have the original package anymore), they gave me a FedEx tracking number …

However, FedEx tells me that “The shipper has prepared your package; however they have not yet given it to FedEx.” So nothing is happening.

I don’t understand this. Since July 24 I had several e-mails — waiting about 2 days average for a response — and we are still not on the way to anything !

VERY unhappy. BLUETTI_CARE — what is going on ??? Your customer service is abysmally bad …

Hi @Avery05, Thank you so much for taking the time to share your feedback—we truly value it, as it helps us keep improving, and we’ve already asked our service manager to look into things thoroughly.

Just to update you: Your package was indeed shipped out as scheduled, but we noticed the logistics provider hasn’t updated the tracking information online in a timely way. We’ve been in touch with them repeatedly to urge a quick update, and we’ll keep following up until it’s sorted.

About the email response timing—we checked into this, and it turns out there was a slight delay due to a system issue with our email platform. That said, except for weekends, we always aim to reply within 24 hours, which is part of our commitment to keeping you well-supported.

To make things right, we’ve arranged an upgrade service for you, and we’ll be sending all the details via email shortly. Please keep an eye on your inbox for that—we hope it helps make your experience smoother.

Thank you again for your patience and understanding. If you have any other questions in the meantime, feel free to reach out anytime!
