Доброго дня Bluetti
Можно мне тоже все последние прошивки для моей станции,для ее корректной и стабильной работы
Спасибо
Hi @Nicholas, Thank you for providing the information—we have submitted it to the R&D department.
Once the new firmware is completed, we will also push it to your unit.
Hi @George2050, I would like to help you.
Now 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. We recommend recalibrating it after the upgrade.
Please let us know if it works.
Hi @Pletenets, yes, we would like to help you.

Please upgrade the firmware tomorrow. Please do not load any device when upgrading it. We recommend recalibrating it after the upgrade.
Please let us know if it works.
Today the new Firmware Upgrade was available and I quickly checked the remaining time and power consumption. It seems to work now as expected.
Thanks for your quick turnaround.
Best regards,

Hello, @BLUETTI_CARE
I have similar issues with the Elite 30 v2 (230V/600W). The first 45% of the charge discharges twice as fast as the remaining 55%. Calibration does not yield any results.
Do firmwares that fix this problem exist for the Elite 30 v2 (European version 230V/600W)?
Can you help me resolve this issue and, if possible, provide a new firmware to correct this?

Привет!
Сегодня было обновление! BMS v1083.07 обновился до BMS v1083.08. После чего было предложено новое обновление с BMS v1083.08 до BMS v1083.99. Обновление скачивается, устанавливается (видно и на дисплее Elite 100 V2 и на смартфоне) пишет что обновлено… Но после проверки снова пишет об наличии доступной новой версии обновления с BMS v1083.08 до BMS v1083.99
Что нужно сделать чтобы это обновление установилось?
Спасибо за помощь!
Hi @Sonixx, that is great, thank you for letting us know!
We will share this good news with our engineers!
Hi @Pivdennyi, we would like to help you.
Please tell us your Elite 30 V2’s SN number and the current firmware version, then we will check if there is any new firmware available.
Hi @George2050, Please rest assured—your firmware upgrade has been successfully completed!
Please disregard any further upgrade notifications and do not upgrade again.
We have notified our Technical Department to remove the upgrade prompt to prevent further inconvenience, and this will be completed by tomorrow.
Additionally, please perform a recalibration and assist us in testing the performance of the new firmware.
I have had a similar issue, although the fast discharge was for random periods near the start and end of discharge. Bluetti tried to help with several updates. This improved one of my Elite 30s more than the other one, but did not completely cure it. They still have the too fast discharge periods near the end. The worst performing Elite 30 does not work very close to it’s capacity due to this. The other is nearer.
I would be very interested if you could post your experience with any updates, and the results.
@Tezzabee I’m really torn about whether I should go ahead and update the firmware or not. My biggest fear is that I’ll end up making the situation even worse than it is now. Since this is a known issue affecting many people, I think it might be wiser to just wait until the new firmware is pushed out to everyone. This would confirm the update’s stability and verified compatibility, minimizing the risk of a detrimental change.

I would say that although the issue wasn’t completely cured, there was no detrimental effect from the updates. I have no idea why they worked better for one Elite 30 than the other though, as they both started out the same and had the same updates. I did a lot of tests using my 300w kettle, so they also had the same usage. I also had another Elite 30 that I returned for the same reason, not realising the next 2 would have the same issue. I hope you are right, and that there will be a general update that solves this issue.
Привет!
BLUETTI Elite 100 V2:

После обновления до BMS v1083.08 отображение потребляемой мощности очень сильно отличается от того что показывает ваттметр и умная розетка! Единственная потребляемая мощность, соответствующая исходящей мощности на дисплее Elite 100 V2 – это 96 ватт от лампочки накаливания в 100 ватт (96 на Elite 100 V2 и 97.2 на ваттметре).
Все остальное и по DC и по AC показывается неправильно! Разница с ваттметр и умной розеткой реально большая, как минимум в десятки ватт для небольших нагрузок. Подключал вентилятор! По паспорту вентилятор потребляет 60 ватт, имеет 4 скорости. Elite 100 V2 для любой из четырех скоростей отобразил потребление в 68 ватт (хоть на первой, хоть на четвертой скорости).
Телевизор по показаниям ваттметра и умной розетки в режиме SDR (Standard Dynamic Range) потребляет ~ 40 ватт (+/-1 ватт), на дисплее Elite 100 V2 потребление ~ 75 ватт (+/-1 ватт) и это почти двукратное увеличение мощности, которое усложняет оценку ситуации.
После выключения телевизора пультом потребление на ваттметре падает до 3.5 ватт, а на дисплее Elite 100 V2 возрастает до 82 ватт! Это нонсенс! Если это подсчет и реактивной и активной энергии, то такая арифметика никому не нужна!
Это очень огорчает, так как не дает понимания того сколько ещё станция проработает до отключения. У нас блэкауты…
We have notified our Technical Department to remove the upgrade prompt to prevent further inconvenience, and this will be completed by tomorrow.
Версия прошивки с обновлением до BMS v1083.99 не установилась! Я снова написал все данные по станции и очень прошу, чтобы технический отдел собрал исправленную прошивку для моего экземпляра Elite 100 V2.
Спасибо за поддержку!
Hello everyone,
I see there is quite some confusion about the power values shown by the power station. However, this is not a measurement error — this behavior is normal and expected.
The confusion comes from comparing measurements taken on two different sides (DC internal and AC-output) of the system:
-
On the AC-output, you usually measure only the active power (W) consumed by the connected device.
-
The power station / BMS measures the DC power drawn from the battery, including all conversion losses.
Example: let’s borrow the tea kettle from @Tezzabee 
The kettle consumes about 300 W on the AC-output.
-
The device does not have a perfect power factor (for example PF = 0.8).
-
The apparent power is therefore about 375 VA (300 W divided by 0.8).
The inverter has to supply this full apparent power, not just the 300 W of active load. As a result, the BMS sees more power and more current than what you measure on the AC-output.
Why does the AC-output measurement appear lower?
Many simple AC power meters:
-
Do not measure True RMS
-
Do not take the power factor into account
-
Average out peak currents
With non-linear loads, current is drawn in short pulses. This extra effective current does load the inverter and the battery, but it is not always shown correctly by basic AC power meter.
Conclusion
Seeing a higher power draw on the power station than on your AC power meter is normal and expected behavior.
Main causes:
-
Power factor lower than 1
-
Inrush currents and harmonics
In short: the BMS measures everything, the AC power meter does not.
Hopefully, this helps everyone understand why you can see two different measurements that are both true.
Hello, impressive wall of text, however:
It’s not normal since I haven’t heard about any other power station in the history of power stations that displays VA (including other Bluetti models), and that is expected by literally no one, except the Bluetti R&D department and you. Give me at least one reason why I should know the VA of my PC.

Hi Mr Stone,
Thank you for your comment, and also thank you so much for using me as an example of why everyone, including me, is wrong to hope that their Elite 30 can be improved so that it functions properly.
You may be interested to know that I have been working with BLUETTI_CARE over the course of several weeks to try to resolve this issue . They have kindly been providing updates which I have been testing, then feeding back the results. I am pretty sure Bluetti would not do this for a non-issue. I certainly wouldn’t.
You may also be interested to know that I have several batteries. 13 of them are manufactured by Bluetti. They span 3 generations of Bluetti products and are in regular use. I also have a few smaller batteries produced by other leading manufacturers. I do therefore consider that I have a good idea of what to expect from them in everyday usage.
The issue isn’t a case of comparing AC and DC output, nor of comparing the screen to a watt meter. If you were party my testing and private communications with Bluetti, you would know that neither of my Elite 30s have an issue with ‘apparent power’. They both show a reading of roughly 325w when operating the kettle. This is in line with the reading shown by my other 300w+ batteries from different Bluetti generations, and from different manufacturers.
The testing was of AC output only. The reading for the watts being drawn does not change. However, for certain periods of usage the remaining SOC drops at a much faster rate than it should. The effect of this issue is that the 288wh Elite 30 performs worse than batteries with less watt hours, for example the 268 watt hour Handsfree 1. The usable capacity of one of my Elite 30s is on a par with, or sometimes worse than, the 256wh River 2 - even with the River 2 not being particularly impressive with its inverter efficiency.
I know from experience that a fluctuation of between 1-3% in the drop in the SOC may occur between each test. A variation of over 11%, or in some cases over 20% is not in anyway normal. The testing has also included (on the advice of another forum user) the starting temperature of the water, and shown that the sped up drop in the SOC is not related to the starting water temperature.
There is also the issue that due to the random nature of these periods of excessively fast drops in the SOC, it is impossible to estimate remaining run time for what I want to run with the Elite 30. I don’t have this issue with any other properly calibrated batteries, including the Elite 200 which is obviously part of the same series.
Although, as you put it ‘the BMS measures everything’ it would also seem necessary for it to measure everything accurately and act in the usual, predictable way in order for customers to fully enjoy their expected, reliable Bluetti experience.
People come to this forum for help and advice. In my opinion, telling customers their issue does not exist, when it patently does, and has been shown to over and over during tests, and without full knowledge of the issue and steps taken to try to rectify it, is not very helpful. 
Hi @VSM,
I think there is still a misunderstanding about what is being displayed and why.
The power station is not “displaying VA instead of W” for the AC output.
What it displays is the DC power drawn from the battery. This is the value that is actually relevant for:
• Inverter loading
• Runtime estimation
By definition, this value cannot be equal to the AC active power measured at the output, because between the battery and the load there are:
• Power-factor effects
• Inverter losses
• Harmonic and peak currents
“Give me one reason why I should know the VA of my PC”
You don’t need to know the VA of your PC.
The power station does need this information, because the inverter and the battery must supply the apparent and distorted current, not just the active watts shown by a simple AC power meter. This value is derived internally from voltage, current, and power factor.
That is why:
• Inverters are rated in VA
• Current limits are based on RMS current
• The BMS monitors DC input power, not AC output power
Many other power stations hide this reality by displaying only estimated AC watts. That presentation is more intuitive, but technically incomplete. In this case, you are instead seeing the actual battery-side load.
So:
• The AC meter reading can be correct
• The BMS reading can also be correct
• They are measuring different sides of the same system
This does not make the behavior “abnormal”; it makes it more transparent — even if it is less familiar.
As a consumer, I agree that this VA-like displayed value is not always intuitive, especially with loads that have a power factor far from 1 (for example, a desktop computer power supply). Personally, I ignore the values because I understand what is being shown. Ultimately, what matters is that the power station can reliably deliver power to the connected devices.
As for other Bluetti models or other brands, I can’t speak for their design choices. Displaying only estimated AC watts is certainly more user-friendly and avoids confusion, even if it conceals some of the underlying electrical realities.
Exactly
I don’t. If I’m using small continuous loads, I want to eyeball the exact remaining running time, taking idle consumption into consideration, because the time remaining on the display gives a very rough estimate (I’m pointing at you, AC200PL+B300K, which I also own). If you know active power consumption, this is the most precise method.
I can, because I’m the customer, and this is a highly competitive niche. Verdict: displaying the information, which 99,9% of the people don’t need, instead of the info, which 100% of the people need - it’s not how you increase your market share and get 5-star reviews.
