Hi @vlad_n, this is a misunderstanding—it is not that we are unwilling to disclose 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.
Therefore, we do not intend to develop firmware that switches between different power logics. In fact, most customers do not need the display of accurate active power. Retaining the original firmware helps the system detect overloads more quickly.
Hi @BLUETTI_CARE. I’m not talking about changing the inverter load and overload calculation algorithm. I’m talking about the logic that displays the power on the LCD screen. These two logics were implemented in DSP v2200.14 and v2200.16. As far as I understand, DSP v2200.16 doesn’t change the inverter load and overload calculation algorithm, but only displays active power.
I think you’re wrong, most customers really do need accurate active power display. Otherwise, this forum thread wouldn’t exist.
@Volodymyr_Yezh Thank you for your detailed feedback.
To help improve the SOC accuracy, we kindly suggest performing two more complete charge–discharge cycles. This process can help the system recalibrate and calculate the remaining capacity more accurately.
In addition, please provide us with the serial number (SN) of your unit and the current BMS firmware version. We will check whether there is a newer firmware version available that includes further optimizations for SOC calculation.
@Volodymyr_Yezh We have pushed the new BMS firmware version 108310 to your device.
Please upgrade it and then perform a full charge and discharge cycle. This will help with system calibration and allow us to observe the device’s performance.
If you notice any issues, please feel free to let us know.
Привет, BLUETTI_CARE!
К сожалению после обновления прошивки (с DSP v2200.14 до DSP v2200.16) я не могу включить ECO-режим ни для DC, ни для AC!
Пункты настройки ECO исчезли из приложения BLUETTI.
Версия приложения BLUETTI v3.0.4
Что нужно сделать, чтобы вернуть возможность переключать ECO-режимы для DC и AC?

Hi @George2050, thank you for contacting us.
As @lavash_bluetti mentioned, we have explained this issue previously, so there is no need for concern – this is a normal phenomenon.
Simply disable the System Switch Recovery function to enable ECO mode.
Hi,
Since a few days I am the proud owner of a Bluetti Elite 100 V2 powerstation.
I bought this unit mainly to handle possible grid outages. I have to sleep with a CPAP device, so the Bluetti is important for me as a backup system. For a CPAP device the 100 V2 may be overpowered, but it can also be handy for other things during grid problems.
I chose this Bluetti Elie 100 V2 because of the specs, its compact size and the many good reviews.
I already tried it a night with my CPAP device and it did the job. Once in a while I heard the fan switching on at a very low speed but it is very quiet and not annoying at all. Great !
But I noticed a power consumption on the display of 65 Watt and that made me thinking, because I knew for sure that it wasn’t that high. ( I use it also on my boat )
So I took my Watt meter to find out for the CPAP load and this meter showed an active power value of only 12 Watt. (no heating used) This was a more familiar value to me.
Why is this value displayed so high on the Bluetti ?
As an electronic engineer I understand the different types of power, so I first assumed the display was showing the apparent power in VA and not the real active power in Watt, because the CPAP internal switched-type power supply is a load that also has a reactive power part.
But the display on the Bluetti 100 V2 clearly shows a “W” symbol meaning real active power, so it should not be apparent power which should be noted as “VA”. The manual shows nothing about this.
Being afraid of having received a faulty unit, I decided to do some measurements.
As a start I used pure resistive loads, that give a power factor of 1, meaning that the active power will be equal to the apparent power. The loads were a solder iron, incandescent light bulbs and a home heater with selectable heating elements.
I found the results below:
Load: Watt meter: Bluetti Elite 100 V2 output display:
- Bulb 15W 17W 0 ?
- Bulb 60W 58W 82 ?
- Solder iron 86W 100 ?
- Solder iron + bulb 143W 156 ?
- Heater 650W 691W 690
- Heater 1300W 1306W 1301
- Heater 2000W 1896W 1878
This table shows at results 2 – 4 the Bluetti has a large deviation of the actual active power value. (too high)
Result 1: is an active power of 17W too low to measure?
Result 5 is almost exact and results 6 and 7 are acceptable ( because the Watt meter will have some misreading too)
It looks like there is no problem with higher (resistive) loads, the problem has to do with lower loads.
If measurements of low power loads are so inaccurate, then how can this Bluetti calculate the SOC at low power loads such as my CPAP with some acceptable accuracy ?
Well, that is maybe the next problem because I also checked the remaining time for my working CPAP:
After a calibration cycle, at a SOC of 100%, the display shows that I still have 99,9 hours for my working 12W CPAP device.
That is too optimistic : 99,9 hours x 12W = 1200Wh. This cannot be done with a 1024Wh battery, also because there is some system power (10W?) needed too…
Being a little disappointed about the faulty low power readings, I browsed the internet for finding things about this issue and that is how I discovered this interesting post on the Bluetti community platform.
I learned that:
- Bluetti says: “For the Elite 100 V2, the screen will display the apparent power when the apparent power of the load exceeds 50W, When the apparent power of the load is less than 50W, the screen will show the active power” Very confusing…
And it doesn’t explain my misreading in case of my pure resistive loads of 58W and 86W. - It seems certainly possible to have more accurate active power readings with other firmware!
Also at lower power levels which I can see in the post of lavash_bluetti
(9 and 19 Watt pictures, nov ‘25) - Other (older) Bluetti powerstations have no problems with their power display.
(pictures of AC180 reading 65W of lavash_bluetti , nov ‘25) - It seems that there is new firmware to solve this, but it is only given to some (complaining) people.
The most strange thing here is that new firmware is not distributed to ALL Bluetti 100 V2 units !
I think that this is a weird choice of Bluetti and I also think that more people will come to complain in future. That will not be good for Bluetti’s reputation…
I understand the technical explanation of Bluetti that the amount of apparent power is taken into account to determine overload conditions. But I agree with lavash_bluetti and VSM that users are not interested in this apparent power values on their display!
Software is flexible and apparent power values can be needed for various calculations but of course a display can show other variables, in this case the ACTIVE power.
So like many others I would like to have a output display with real active power W values together with a proper SOC value, both calculated with a reasonable accuracy, also at low power loads !
BLUETTI please help me with some new firmware, it is all very confusing and frustrating…
I hope that I have given enough information, but of course I am willing to add more info.
Thanks !
My SN and firmware:
Hi @LvdK, thank you for reaching out to us. It seems you’ve already reviewed our previous responses on similar issues and have a good understanding of the situation.
We have not pushed this firmware update in bulk because most customers are not concerned about whether the screen displays active power or apparent power. Our system is designed this way to help detect overloads promptly.
However, as per your request, we have applied to push the new firmware to your device. We will complete the push within 1 working day.
Please upgrade the firmware next Monday. Please do not load any device when upgrading it.
Please let us know if it works.
Thank you for the fast response, I really appreciate that !
But I hope that Bluetti realizes that my display was also wrong with pure RESISTIVE loads !
So NO difference in apparent OR active power, also in this case just WRONG values on the display.
I think that ALL customers allways want an accurate display, so WHY not pushing new software in bulk ??
This should be so much easier then repeatedly sending individual updates !?
Reasons I can think of:
- I don’t think so, but maybe Bluetti is lazy and has an attitude “keep silence if people are not complaining” ?
- Is the new firmware is still not tested good enough to be pushed to everybody ?
- Will this new software solve this display issue, but will it give other problems that Bluetti does not want us to know ??
So the big question stays : WHY not push this firmware to EVERYBODY ??
But thanks , for sending me new software and as soon as I have tested it, I will certainly let you know !
Kind regards, LvdK
No new firmware yet…
Unfortunately my app still shows that I am up to date with
ARM v2186.16
DSP v2200.14
BMS v1083.08
I don’t know what I am doing wrong…
Still no firmware…
Holidays ?

THX!
I hope you will receive an answer soon…
I had an answer 11 days ago, but I’am still waiting for the promised new software.
They seem vanished from the earth…
Hi @Dragline, thank you for contacting 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.
Please let us know if it works.
@BLUETTI_CARE
Hello. Thank you for providing the DSP220016 firmware. However, I don’t see the BMS 1083.10 firmware. If possible, please help!
EL100V22548111562566
THX!
I had the new DSP v2200.16 firmware. Thank you !
I did some measurements with satisfying results.
My firmware is now:
ARM v2186.16

Bulb 15W (2) 13W 14.7W 1
Bulb 60W 56W 57.6W 1
Heater 650W 672W 674 W 1
Heater 1300W 1303W 1304W 1
non-resistive loads:
LED lamp OSRAM 10W 0W 10.2W 0.97
CPAP, working 0W 8.3-12.2W 0.41-0.5
Phone charger Samsung 15W 17W 0.49

kitchen mixer (2) 83W 86W 0.98
power drill low rpm 54W 56W 0.31
power drill full rpm 201W 203W -
switched power supply 12V,5A 77W 77.3W 0.58
CONCLUSION:
Assuming that the Bluetti display is of course not meant for accurate measuring,
I think it is rather good now!
Of course lower loads are difficult to measure, but I hope that the Bluetti 100V2
will calculate the remaining time and SOC with reasonable accuracy...
For me this is important for my CPAP nights!
I will recalibrate the unit now and then I will do some SOC tests.
Thanks for now!
