@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.
Hi @SammyK, the technical department informed us that this was a server issue, which has already been fixed. We would like to check if your Elite 30 V2 is functioning normally again?
@BLUETTI_CARE
I reported 2 problems. I’m assuming the server issue caused the lack of energy statistic recording between 12-24 and 12-29. However, the ECO mode is still not working and has not worked since I installed the updated software. Did you report both problems to your technical department?
Hi @SammyK, Yes, we have already reported both issues to our technical team.
The server issue has been fixed.
As for the ECO issue, please note that in the new firmware we have made ECO Mode and the System Switch Recovery function mutually exclusive (you can only enable one of them). This is because these two features conflict with each other—one controls turning the output off, while the other controls turning the output on.
Since the ECO Mode and the System Switch Recovery function can not be used simultaneously. We would like to know if this function was enabled by default after you performed the firmware update? If so, ECO Mode will not be available.
@BLUETTI_CARE
The System Switch Recovery is Disabled. Since I haven’t had any need to look at the Advanced Settings before now, I’m assuming it has always been disabled. All I know is that before updating to the latest software/firmware updates my Elite 30 ECO mode worked as expected.
Hi @SammyK, Yes, we have intentionally set this mutually exclusive option in the new version, which is more logical.
Can you now see the ECO mode?
@BLUETTI_CARE
Can I now see the ECO mode? The ECO mode never DISAPPEARED. It stopped working after installing update!
Do you not understand what I’ve been telling you?
System Switch Revovery DISABLED
ECO mode ENABLED
A/C and D/C outputs STILL DO NOT SHUT OFF when load drops below set wattage values over the specified time.
Before installing updates GOOD
After installing updates BAD
Hi @SammyK, to troubleshoot this issue, we need you to send us a screenshot of your ECO settings, including how the AC and DC load power are configured, as well as the actual power of the connected loads. We will then further verify and investigate the matter accordingly.
@BLUETTI_CARE
Let me explain how I use my Elite V30. It is a UPS for my pellet stove. The stove is only used in the evenings, and I shut the stove off when I go to bed. Pellet stoves take time to shut off their exhaust fan and the fan continues to run until the exhaust temperature drops below a safe value.
I set the AC-ECO to shutoff the AC outlet to the stove after the wattage drops below 20 Watts for 1 hour, giving the stove plenty of time to safely remove any residual smoke.
I did this because Section 5.4 of the manual notes that AC-ECO is not available when **CHARGING ** with AC power.
So, I used the Time Control UPS, and set the CHARGING time to be between 4:00 and 5:30 PM. This allowed me to charge my Elite 30 once a day and still have ECO Mode safely shutoff the AC outlet 1 hour after fans shutoff. The only interaction I needed to do was to turn the AC outlet of my Elite 30 back on before restarting my stove in the evening.
This worked as I just described before installing the latest firmware.
Now ECO mode only works when AC Power (Grid Power) is disconnected and Elite 30 is running off battery power. Elite 30 no longer allows ECO Mode to operate during the
Time Control UPS non-charging periods.
I attached the screenshots you asked for, but hopefully my above explanation gives a clearer picture as to what is going on.
Hi, @SammyK ,We sincerely apologize for the inconvenience. In the latest firmware version, the ECO mode behavior is indeed as you have observed. From a design perspective, this change was made mainly with typical backup / UPS usage scenarios in mind. When grid power is available, automatically turning off the AC output could negatively impact the user experience, so the logic was adjusted and optimized accordingly.
For your specific use case, we recommend considering the use of an external timer switch or timer outlet. By pairing a timer outlet with the system, you can achieve a delayed power-off after the stove shuts down, ensuring the exhaust fan has sufficient time to run safely, without relying on ECO mode. Additionally, a timer outlet can also be configured to automatically restore power at a preset time, potentially allowing the stove to turn on automatically as well.
If you prefer to keep your original workflow, you may also consider rolling back to a previous ARM firmware version, in which the ECO mode behavior matched your earlier usage scenario.
@BLUETTI_CARE
I’m not interested in purchasing an external timer that may or may not be able to do what ECO Mode was capable of doing before the update. Using ECO Mode in conjunction with Time Control UPS was a great feature, that sadly no longer exists with the latest updates.
Rolling back to a previous ARM firmware seems to be my only option.
