It optimizes the issue of frequent PV charging relay switching in low light conditions.
It relaxes the charging voltage for the grid-enhanced mode, allowing compatibility with a standard voltage input of 70%-130%, enabling more generators to charge.
It resolves the random shutdown issue after fully charging.
We have confirmed that the new DSP will not affect the turn on time, but the BMS might. However, we noticed that you haven’t upgraded the BMS recently. Therefore, we suggest you record a video, upload it to a cloud drive, and share the link with us to check if everything is functioning normally.
Hello @BLUETTI_CARE . Thank you for the information about the changes in the DSP.
I don’t quite understand which BMS is outdated. At different stations I have (in brackets the number of stations with this version) v1033.12 (1), v1052.02 (2).
I recently checked for updates on all of them and none of them had information about the update.
With the BMS version v1033.12, the AC180 station number 2313000365676. This is the one that does not turn on when it is charged to 100%, turned off, but connected to a 230 volt network.(it was connected to the network before turning off the button).
Another station also does not turn on, but it is completely new. And it works without any problems at all. Judging by the software and the number, the release is 2024 (IOT v9046.01, ARM v2124.02, DSP v2126.02 BMS v1052.02).
And what video do you want to see? If the station turns on by itself? Then everything is simple there. The station is charged 100%, turned off, but plugged into a 230 volt outlet (it was connected to the network before turning off the button)… After different times, the station turns on by itself. I can shoot if you confirm the need.
“After different times, the station turns on by itself. I can shoot if you confirm the need.”
Came here for same problem, station works in bypass state from AC, turns on the fans by itself each 1-2 hours, yesterday accidentally the display was enabled and i saw the input wattage 350W, while the output was 60W and station working in by-pass UPS mode. We have some problems with power leakage, ladies and gentlemen

Hi @lavash_bluetti, Your BMS version v1033.12 is the latest. For other machines, if there are no issues, there’s no need to upgrade the BMS. We only push new firmware after thorough testing.
Regarding the machine with SN AC1802313000365676, has the issue been resolved? What is its DSP version? We plan to push a new DSP to address the shutdown issue after charging.
We would like to get a video comparing the startup speed after upgrading the DSP to see if there’s any impact on the boot time.
Hi @Kostyantin, We found that your firmware version is quite recent. If there are no other issues, there’s no need to upgrade.
We’d like to know if your AC180P is connected to a power source. If it is, it will automatically activate and turn on, which is normal.
The fan turning on every 1-2 hours is also normal, as the machine detects an increase in internal temperature and activates the fan for cooling. Once the temperature drops to a certain range, the fan will turn off. Additionally, please ensure that the area where the machine is placed is well-ventilated to aid in heat dissipation.
The input power refers to the charging power of the AC180P, while the output is 60W. Apart from the load, the remaining power is used to charge the AC180P, which is also normal and does not indicate a power leakage issue. Please rest assured.
Hi @BLUETTI_CARE !
The AC1802313000365676 station currently has the following software
ARM v2074.07
DSP v2078.07
BMS v1033.12
The station works without any issues. And this station after charging to 100% and forced shutdown (pressing and holding the power button), does not turn on by itself, remaining connected to the outlet.
The other two stations in the same situation turn on by themselves after a while and this raises questions for me. They currently have the following software:
ARM v2074.07
DSP v2078.07
BMS v1052.02
Hello, the fan sometimes turns on at high speeds when the load is only up to 90wt, and it may not even turn off at all, you have to reboot the station! Began to make a lot of noise after the update!

Hi @lavash_bluetti, It seems that the firmware on these 3 AC180 units is mostly consistent, with only minor differences in the BMS, though this should not cause such discrepancies.
When you mentioned manually shutting down the first AC180P, and that it doesn’t automatically turn on afterward, this is normal behavior. Only re-plugging the charging cable or turning off and restarting the grid would trigger the AC180P to power on automatically.
For the second and third units, which turn on automatically under similar conditions, we want to confirm: were they also manually turned off by pressing the power button? After that, was the charging cable re-plugged or was the grid disconnected and restarted at any point?
Hi @qwerty1, This seems like normal behavior. We would like to know whether you are using AC or DC load for this 90W device.
During both charging and discharging, the internal temperature of the battery cells increases, causing the fan to automatically turn on for cooling purposes. Unfortunately, the fan cannot be manually turned off, nor can this be achieved through a firmware upgrade, as it depends on not only the load power but also the internal cell temperature and environmental conditions. We recommend placing the AC180P in a well-ventilated, cool area or using an external fan to help with cooling.
The fact that the fan turns off after restarting is also normal. The fan’s activation and deactivation have hysteresis, so after restarting, it may not turn on again.
All three stations are AC180.
Yes, all are manually switched off and the power cable is left in the socket. The voltage did not disappear and no one touched the power cable connector.
And all stations are charged to 100%.
In the ones described above, the first station does not turn on by itself (it has BMS v1033.12).
The other two turn on by themselves. At the same time, while they had DSP v2078.06, they turned on by themselves quite quickly (approximately within the first few minutes). After installing DSP v2078.07, they also turn on but noticeably later - sometimes after ten minutes, sometimes after a couple of tens of minutes. But the interval has clearly increased.
Perhaps this is due to changes in network voltage and frequency. Recently, I often see voltage in the range of 233-240 volts and deviations to the lower side in frequency up to 49.95 Hz. It may also be a reaction not to voltage values, but to voltage changes.
Hi @lavash_bluetti, Under normal conditions, if the AC180 is turned off while charging, it will need either the power cord replugged or the power button manually pressed to restart.
The delay of a few or several minutes for activation may be due to an unstable grid voltage, rather than a firmware issue.
Your analysis is correct.
Greetings. After each operation of ac180p, the time changes to the lower side, less and less, after each discharge, charge! I see it when the charging station is connected to a high-voltage network! What does it mean, and what will happen when it reaches the 0 mark?
Hi @qwerty1, Please rest assured, this is normal.
The indicator shows Remaining time indicator. When charging, it displays the remaining charging time, so the value will decrease as it charges. When discharging, it shows the remaining runtime, and the value will decrease as the battery depletes.
When it reaches 0, it means the machine is fully charged or fully discharged and needs to be recharged.
Hi @BLUETTI_CARE. I have had AC180P station for a few days and noticed a non-critical but annoying issue. I usually load the station with less than 100 watts; in this case, it is dead silent. But sometimes power consumption can surge to ~120 watts for a few seconds, and the station turns on the fans. The problem is that though the surge time is just a few seconds and then consumption drops to 25 watts afterward, the fan keeps going and going (definitely for more than 15 minutes), blowing cold air. I’m sure the station internals are cold because this happens when I turn it on from a cold start, and the ambient temperature is around 20 Celcius. Other times, it behaves correctly and shuts down the fans after a few minutes (I assume it waits these few minutes in case there will be another surge not to keep cycling the fans). But when it does not, it is really irritating because I specifically have chosen this station over another known competitor because, according to feedbacks, it ought to be silent for low loads. The current fix I use is disconnecting and reconnecting the load - the fans stop in this case, but it is not always convenient.
Other than that, I’m happy with the station.
Is this a known issue for which a solution will be available soon?

Hi @Roman_t, We found that your firmware is the latest one.
We believe this issue might be related to your load. When your appliance starts, it may cause a sudden power surge, which in turn triggers the fan to spin at high speed.
Please note that for some machines with built-in compressors or condensers (such as fridges, air conditioning, pumps, and freezers), the surge power will be 3-7 times higher than the rated power, and it will keep several seconds after it is just turned on.
The fan on the AC180P operates under the following conditions:
Charging/Discharging Power: When the charging or discharging power reaches a certain threshold, the fan will start.
Internal Temperature: When the internal temperature of the AC180P reaches a certain level, the fan will also start. As the temperature decreases, the fan will stop.
Additionally, each time the unit is powered on, the fan will briefly run as part of the self-test.
When the heavy load is disconnected, the internal temperature of the machine may still be high, requiring the fan to continue running until the internal cooling is sufficient for the fan to stop.
As you mentioned, when you turn off and then back on the AC output, the fan can turn off immediately because the fan runs a self-test after restarting.
We recommend that you do not artificially shorten the cooling time, as maintaining the internal temperature helps with battery health. You might also consider using an external fan to aid in cooling the AC180P, which may help accelerate the cooling process.
Good day. I have 2 Bluetti AC 180p stations. One works quietly and perfectly, and the second one under a similar load produces an audible static electrical noise (when AC function turning on) and also the fans at a load of 100 watts are constantly work and noisy.
The parameters of the station are below:Good day. I have 2 bluetii AC 180p stations.

Currently I am using my AC180P for low AC loads (20W - 40W).
When I apply the load, it remains completely silent for ~2h, and then it turns on the fans for several minutes. The problem is they are turned on to a very high speed (and produce a lot of noise) - and would remain at this speed, until being turned off after several minutes.
With 100W+ loads though fans start to spin almost immediately, and keep spinning the whole time - but on a much lower speed and producing much lover level of noise.
How do I fix this high level of noise on low loads?
Hi @MykhailoS, I have now applied to upgrade your firmware.
Please upgrade the new DSP. Please do not load any device when upgrading it.
Please let us know if it does help.
Hi @Merle, I have now applied to upgrade your firmware.
Our IT department will push the new DSP to your unit in 1 workday.
Please upgrade the firmware tomorrow. Please do not load any device when upgrading it.
Please let us know if it does help.
An update has arrived. I installed it. The station began to work noticeably quieter, but after 20-30 minutes of operation under a load of approximately 100 watts, the fans turn on at full speed and continue to work until I turn off the AC button.
