Low grid voltage error on AC180P

Hello. I constantly get low grid voltage error even when voltage is around 190+ volts (even in Silent mode and Grid Self-adaptation on).

When I have this error device doesn’t charge itself and pass-through function stops working so my appliances are powered by the power station even when I have power in the grid. This is very inconvenient!

I have 2 questions:

  1. Is it possible to lower minimal charging voltage?
  2. Is it possible to make pass-through function work when there is low voltage in the grid and the station cannot charge itself?

If your grid nominal voltage is 230 volt and you get around 190 volt at the plug it means you have serious power distribution issues and you should seriously look at them first instead of finding a way for your device to work with such a low voltage which falls below the minimum accepted voltage range.
Your device is safely disconnecting itself from the grid and you can’t force it to ignore safety, the only way to fix this problem is to look into why you don’t have a rated voltage on the outlet.

Well, I know the reason behind this. I don’t have a rated voltage on the outlet because fu*****g Russians destroyed nearly half of the power plants in my country so I’m not sure if I can do anything with it… I have electricity for like 12 hours and half of that time it’s 190 volts so I’d like to have an opportunity to charge my device during those precious hours or at least be able to power my appliances without discharging my power station. I can understand why they would not let me to charge the station with 190 volts but I don’t understand why my station doesn’t allow power to go directly to my appliances.

Yes, I agree with @ndwr 's opinion. The normal input voltage should be 230V, but the actual input is only 190V. As a result, the AC180P reports an error and cannot charge or bypass load. We will report this to the R&D department and ask if they can create a new DSP firmware to solve this issue.
Hi @Kvano , could you provide us with your SN and the current DSP version? We will try to resolve the problem.

Sure! I’d really appreciate it.

Hello i have the same problem. If possible, reduce the threshold of the minimum voltage required to charge the device. Thanks.

Hi, You can try to use a voltage stabilizer on input

It will require a rather expensive and a big one so it can handle up to 1.8k load.

Yes, smth like Gemix GDX-2000

im having same problem, id like the same solution too if its posible, thx

Hi @Kvano , @Dod690 and @Jukrek , We have forwarded your request to our development team, hoping they can quickly develop the corresponding firmware to resolve the issue. We will contact you as soon as we receive their response. I appreciate your kind understanding and patience.

I’m having the same issue. If it’s possible please allow lower voltage charging. Thanks!

@BLUETTI_CARE.
Please help, I have the same issue but with my new AC180T.
The voltage in my network is almost constantly about 190 volts and the station does not charge. It is impossible to influence this because our power grid is very badly damaged by the aggressor.

AC180T2416000502068
ARM v2097.08
DSP v2096.07 (update available to v2096.09)
BMS Pack 1 v1038.14
BMS Pack 2 v1038.14

Can you please provide any solution. Or should I update DSP to v2096.09 to resolve this issue?

Hello, I have a new problem: there is no way to change the charging mode. Yesterday, before going to bed, I started charging the station in silent mode, but already today I cannot choose another charging mode. Eco mode is disabled, grid self-adaptation on/off does not give results. Help @BLUETTI_CARE

The same situation. When I choose silent or turbo it doesn’t change at all, staying at standard. Yesterday everything worked properly. Please help me. @BLUETTI_CARE

If you want to have standard mode back, you can reset to factory mode. But than you won’t change to any other mode (

Hi @Kvano , @Jukrek and @umudov.s.i13 , We offer a custom firmware DSP v2088.04 for the AC180P to customers in regions with unstable power grids. If you have already upgraded to the regular version of DSP v2088.04, we will temporarily rename this custom firmware to DSP v2088.99. If you haven’t upgraded to the regular version of DSP v2088.04 yet, we will directly push this upgrade to you. Please help us test the performance of this custom DSP to see if it can assist with AC charging in unstable power grid environments. We are waiting for your feedback.

Hi @Dod690, @Stas1983 , Regarding the issue with switching charging modes, our app technical engineers have identified the problem. They are currently working on an urgent fix and it will be resolved soon. This issue is not related to the firmware upgrade. Once we release the new version of the Bluetti app, updating the app will resolve the issue.

i do have custom version of DSP 2088.04, because i had an issue with AC180P turning off while power shutodowns
will this version overwrite the one that fixed my previous issue? or can i somehow get both of them?
if new one includes previous fix then push it directly to my device please

I have the same question as Jukrek. I already have 2088.04 version and I’d like to have both fixes - for UPS and for unstable voltage. Thanks!
