Hi @DmitryDr, thanks for the update. We’re glad to hear the new firmware works well.
It’s our pleasure to help you!
Hi @Volodymyr_Yezh, thank you for getting in touch with us.
We don’t have a firmware for this issue, so we can’t fix it remotely.
We recommend you try DC charging and rule out the impact of extremely high or low ambient temperature on the battery.
If it still doesn’t work, you’ll need to contact the seller to arrange warranty service.
Hi @theadviser, we have consulted our technical department about this issue, and they informed us that upgrading to BMS v1083.09 will be more helpful for your problem.
Please upgrade and recalibrate the unit. We look forward to your feedback.
Hi @chem, thank you for your feedback.
We’d like to confirm whether you have recalibrated after upgrading the BMS. Generally, recalibration will help.
Regarding the grid charging issue, could you switch to standard UPS mode and test it again?
Hi; @BLUETTI_CARE,
I recalibrate the device and I think SOC problem is solved. Thank you very much. But I could not find a way to test grid charging issue when input is closed by the device at standard UPS mode. Because of pass through charging. It is still occurring at PV priority mode. Also I think there is still a problem especially at low output measurements. Can you give me an update for more correct output measurements.
Best regards.

Hi @chem, thank you for your feedback.
There is a certain delay in the APP, which may result in delayed data transmission.
Inaccurate readings under low load are also normal, as the power is too low and sampling errors can easily occur.
We have no other new firmware available right now.
Hi, @BLUETTI_CARE
Following up on the earlier posts here — it looks like I’m seeing the same behavior on Elite 200 V2.
Bluetti shows ~120W, while external meters show ~60W real usage (checked on both input and output in pass through mode), so roughly ~2x difference. The readings from the station are quite misleading.
Seems very similar to what’s being discussed here (possibly apparent vs real power?).
Can anyone confirm if this also applies to the 200 V2 or if there’s any firmware fix? In its current state, the data is basically unusable.
Thanks!

Hi; @BLUETTI_CARE
In my previous message, I said SOC reading problem is solved. Unfortunately it was wrong.
As you can see from the picture. While charging from the grid (460 Wh) SOC jumped from 69 % to 100 % in just five minutes. I am really frustrated at this moment. I can not use PV charging. I can not trust any value show on device. Can it be fixed with software update or Do I have to apply for guarantee.
Thank you
Hi @AngryPearl, thank you for getting in touch with us.
When the apparent power of the Elite 100 V2 or Elite 200 V2 under load exceeds 50W, the LCD screen will display the apparent power; when the apparent power is less than 50W, the LCD screen will display the active power.
Let us explain the original intention behind the initial setting: we did consider displaying only active power uniformly. However, this would lead to certain issues—because the inverter needs to determine whether there is an overload, especially for inductive loads, which must be judged based on apparent power.
We have currently developed a new firmware for the Elite 100 V2 that will enable the device to display active power at all times.
As for the unit with the Elite 200 V2, we do not have any related firmware developed for it.

Hi @chem, thank you for your update.
Your firmware is already up to date, and we do not have any additional new firmware available to push.
We would like to confirm whether you followed the standard recalibration process. Please do not load any appliances when charging.
If you have only used AC charging, please also try DC charging.
When discharging, we recommend using a stable load with relatively low power. Does this help resolve the issue?
If the battery level still jumps abnormally, we will need to arrange warranty service for you.
@BLUETTI_CARE
Hi,
Thanks for the explanation, but this behavior makes the readings very misleading.
Displaying apparent power as “W” without any indication is confusing, especially since the device switches between active and apparent power depending on load. From a user perspective, there’s no way to know what is actually being shown.
In practice, this makes the power data unreliable and hard to use.
If Elite 100 V2 can display active power consistently, the same should be implemented for Elite 200 V2.
Thanks.
Hi @AngryPearl, thank you for sharing your feedback.
Currently, we do not have firmware available for the Elite 200 V2, as there has been relatively low user demand for it.
We have passed your suggestion along to our R&D team, and we hope they can complete the new firmware as soon as possible.
Hi, @BLUETTI_CARE
Thank you for your attention. But problem still exist. What I have done so far is as follows;
- I discharged it very slowly with app. 10-15 W load. It took app. ( I am not kidding) more than 10 hours to deplete final 1%.
- I charged it from PV. Charging is very consistent. But again discharge is very inconsistent. Especially SOC values over 70 % SOC readings get more inconsistent.
Problems with my power stations;
- It can not measure inlet wattage. Currently I am using 1A AC charging speed. It equals to 230W. But when charging watt meter says, power station only draws 160 - 170 W.
- Power station shuts the grid connection when set SOC is reached with PV charging. But it still draws all the power from the grid at PV priority UPS mode. My TV setup uses app. 13 W at stand by position. Even with a closed grid; it still draws 13 W from the grid. Both inlet and output wattmeter’s confirm this value.
- It can not measure output wattage. As I said before, My TV setup uses app. 13 W at stand by position but on power station measures this value 55 W and with a closed grid connection this value jumps to 92 W. Can this much difference be between apparent and reactive power.
There are also good things to. It works perfectly as an UPS. When grid is down there is not even a slightest flicker.
I am not sure about applying to warranty because in Turkey it is always a mess. I am sure there is no one in Turkey to repair any kind of problems in this device. And I do not think a replacement will be possible.
Best regards
Hi @chem, thank you for your update.
When you charge with a current of only 1A, the current is too low for the system to measure accurately. Would the result be different if you increase the charging current?
It is normal that the system still shows AC input power when loads are connected, even in PV priority mode. Due to factors such as shadows and wind, PV charging power is highly unstable. To avoid affecting the loads, the system bypasses them to the grid to improve output stability. Otherwise, devices like TVs may frequently shut down or restart.
The difference between apparent power and reactive power is indeed quite large.
Apparent power (S) is the vector sum of real power (P) and reactive power (Q).
It appears that the unit is functioning properly. Since maintenance support is not convenient in Turkey, we recommend that you continue using it as is. No repair is needed.

Hi @JoeD, thank you for getting in touch with us.
I have applied to upgrade your system to our IT department. If the new firmware is available, they will complete the push within 24 hours.
Please upgrade the firmware tomorrow. Please do not load any device when upgrading it.
After that, please recalibrate the system.
