AC180P TEMP flashing cannot charge

Product Discussion BLUETTI Apex & AC Series

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.
