I updated my Elite 30 V2 with the latest IoT and System versions. Now there are at least two features that no longer work correctly. The Energy Statistics only logs SOC (State of Charge) and nothing else. The ECO mode does not shut off the AC load outlets when wattage and time limits are meet. Yes, I tried the famous “fix all” of draining the battery down to 0 and recharging it to 100. Didn’t work - nor did I expect it to.
Regression Testing should take into account all the possible software and hardware variations that may exist out in the real world BEFORE releasing any new updates! Very disapointed to say the least!!

I would suggest you edit your post to begin with @BLUETTI_CARE at the begining, this will highlight your issue to Bluetti.
As an aside, I reviewed and tested a pre production Elite 100 v2. I found an issue, reported it and they pushed an update to me. I found another issue, so another firmware update push etc. I found, from memory 3 or 4 such issues during testing and got an update usually within 24 hours. (Weekends and holidays may delay, lol)
As a retired mech/elec designer, it is almost impossible to test for every scenario. The key is, when an issue arises, formally report it and hopefully get an expedient resolution.

Thanks, Mandp. I’ll give that a try. My concern going forward is if they send me a patch to fix my unit’s problems - what happens when they release future updates. Will my current problems come back because my unit is somehow different?
Your Beta testing experience was great because you unearthed problems that were not seen or expected. You used it as a real user would. Thanks again!
@SammyK As with all software updates, there is always a possibility of unexpected issues, just look at big tech i.e. Samsung or Apple. Once those situations become apparent, they are usually very quick to rectify with a further update. Scenarios are infinite, not perfect, lol.
BTW - when I said add the at Bluetti Care, I meant edit your original post to start with that, lol.
@Mandp The edit option must have a time limit. There was no little pen/pencil on my original post. I was hoping @BLUETTI_CARE would have access to the thread. Guess I’ll repost if I don’t hear back from them soon. Thanks again!
Have you ever had an issue with compressors/refrigerators during testing?
Were you fine with this model displaying VA instead of watts?
@VSM First, I did extensive reporting on the Elite 100, please search for those reviews as I am not going to go through it a second time. That said, in brief;
I have a 500+ litre, home inverter compressor fridge, Mitsubishi. A cheap 90lt drinks fridge and an Engel 40lt Combi fridge freezer. These were tested. I also have a caravan 110lt Dometic fridge freezer and a 30lt Dometic Drawer fridge. The 110lt has a switched 240VAC power brick, which is not normally used as it is left on 12VDC all the time and the 30lt is hard wired 12V only.
The 510lt Mitsubishi, 110lt Dometic and Engel all worked very well, but the displayed power use on the Elite 100 was around 10% higher than a power meter I had to the fridges. This is because - the Elite 100 inverts power from a battery, which has an efficiency cost. Therefore I assume the displayed power is what it costs the Elite 100 to provide the metered power, the fridges actually consume.
I do have issues with the cheap 90lt - When first tested it did not work at all. I did receive a number of firmware update pushes from Bluetti following other observed issues. The last time I tested this fridge, it appears to work, but the normal metered approx 90W of load, shows 140-150W on the display of the Elite.
I can only assume that there is something in the fridge circuitry that the Elite does not like i.e. feedback, ripple etc. I’m retired, I do not have access to osciloscopes and other lab test gear. I’m limited to AC, DC power meters and a reasonable clamp ampmeter and my knowledge and experience to make these assumptions.
I asked myself a few questions during these tests and came to an answer for each…
- Does it allow grid backup in a power outage, within the limits of its inverter and battery capacity for my use? YES.
- Does it do what I expect it to do in my particular caravaning-RV environment? YES.
- Following Bluetti’s prompt firmware updates on this pre production model, is it working as my other power stations have. YES and with some improvements.
- Is it perfect? NO, nothing is! I have dozens of electrical/electronic devices, both 240VAC, 12VDC and USB, all working as intended. That, one cheap beer fridge is an anomolly in that list, is ok with me. In a grid out, I would put some beers into the big fridge and turn the “cheapy” off. This would also extend battery capacity and inverter load.

Hi @SammyK, we take the issue you raised very seriously.
Generally speaking, an IOT upgrade should not cause such a problem. We conducted thorough testing before releasing the new firmware. We consider that after the app upgrade, some default settings might have been modified, which triggered this issue.
Special thanks to @Mandp and @VSM for their attention to and insights on this matter. Could you please provide the SN code and current firmware version of your Elite 30 V2? We will submit this information to our app team for further analysis. Please rest assured that we will follow up on this matter continuously.
@BLUETTI_CARE,
I currently have the following firmware versions installed on my Elite 30 v2:
IoT v8024.11
ARM v2203.08
DSP v2202.11
BMS v1087.05
Can you tell me what’s new in:
IoT v8024.12 compared to IoT v8024.11?
ARM v2203.11 compared to ARM v2203.08?
BMS v1087.08 compared to BMS v1087.05?
Hi @SammyK, thank you for providing the detailed information. We have submitted it to our technical department for analysis.
We will contact you as soon as we receive a response.
Hi @vlad_n, the new firmware for the Elite 30 V2 has added a smart fast-charging mode, revised the calculation method for remaining charge and discharge time, and optimized the issue of RFID activation interference.
We recommend that you test the device after upgrading the firmware.
