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.

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.

BLUETTI Elite 100 V2:
EL100V22527008961344
IOT2531500930424
IOT v8024.11
ARM v2186.15
DSP v2200.14
BMS v1083.08
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 @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.

Hi @Tezzabee,
I have also recently become the owner of an Elite 30 V2 and have tested it extensively. You can check out my results here: Follow-up — Bluetti Elite 30 V2 with High Standby Power Consumption (Final Results). Maybe you can compare them with your Elite 30 units.
I have never said that the issue does not exist. I only want to emphasize that both power measurements are correct, but we need to be realistic and honest: they are two different measurements. One measures the DC current internally via the BMS, while the other measures the current externally using a cheap meter that does not account for all factors.
Moreover, the sensors both on the BMS board and in an AC wattmeter are not extremely accurate. There has been a lot of fuss about this, judging by the length of this forum post, even though the deviations are technically within normal tolerances. If Bluetti were to equip the Elite 30 V2 with the very best sensors, it would increase the cost by approximately $40–60, making the product less competitive in the market.
If having the most accurate power station is really important to you, you would probably have to build one yourself. I haven’t seen one available on the market for $200 or less.
Another issue is that custom firmware is continuously being developed for anyone who requests it. This does not really help the situation. People who truly have a problem with their BMS board should return the product via RMA so Bluetti can investigate the issue. Additionally, whether the station is a 110V or a 230/240V model also matters, as there can be significant performance differences.

Hi @VSM,
I completely understand you, but the larger the inverter, the less accurate the value shown by the power station becomes under low loads. In your case, it might have been better to build your own power station or home battery. Than, you could have chosen the inverter that perfectly fits your needs and avoided this problem. I also fell into the same trap myself with a small load on a 600-watt inverter (Elite 30 V2).
A power station a niche? If even Lidl is entering the market (The Netherlands) with its own power station, I would say it’s no longer really a niche.
I don’t entirely agree. As long as the load is between 0–20 W or above 35 W (on my Elite 30 V2), the value is displayed reasonably accurately. Of course, there will always be circumstances where it deviates slightly, but we have to remember that this is a power station. We shouldn’t go overboard in the pursuit of perfection.
I’m talking about constant loads from 100 to 350W, with short-term heavy loads over 1kW (microwave, espresso machine, kettle). I’m pretty glad with the readings from my other 2 bluettis in the ranges I mentioned above. Except for the third one (Premium 100).
Yeah, I’m not doing that, and I don’t need it because that’s not my case. See above.
Ok. INDUSTRY. Are you happy now?
I don’t demand perfection. I need a basic functionality, which all of the existing power stations DO have in this INDUSTRY, instead of the useless one.
What point are you even trying to make here? You’re just wasting my time arguing over nothing.
