Elite 30 V2 - PV charging while turned off?

Product Discussion
1

Hi, I have the new Bluetti Elite 30 V2 since a week and I am very satisfied.

I only found an issue:
It is connected to the Bluetti 100W solar panel all the time.
When the sun comes up it starts charging, but the Elite 30 V2 itselfs turns on while charging.
This means a lot of wasted energy, because the Elite V2 seems to loose about 2% of SOC per hours itself.

Is it possible to let the Elite 30 V2 charge via PV while it is absolutely turned off,
so that it does not loose energy constantly?
If yes, how could I do it?

Thank you very much!

Hello, please inform your BMS and SN so that we can register and upgrade it for you.

Hi, thank you very much!
The BMS is v1087.05

  • Is there a way to charge via PV while the Elite 30 V2 is turned off,
    or else a way to reduce the stand-by energy consumption?

  • Is it possible to set the intensity of sun light from when on the Elite 30 V2 starts charging via PV?

  • Is it or will it be possible to set a timer for to wake up in stand-by modus and start charging?

Thank you very much!

Hello,
Thank you for your inquiry! Regarding your questions, the Elite 30 V2 cannot be charged via PV while it is turned off. Additionally, it seems that the Elite V2 is losing about 2% of its SOC per hour in standby mode, which is not normal. Therefore, we recommend updating the BMS to try and resolve this issue.
Please provide your device’s SN code so we can proceed further.
Thank you!

Hi, thank you very much!

The BMS is v1087.05, it is the latest version according to the app.
The device SN is EL30V22526003554170.

The losing of around 2% SOC per hour is normal due to 4,5 Watt self-consumption in stand-by modus I guess.
( 288 Wh / 4,5 W = 64 hours ; 100% SOC / 64h is about 1,6 % SOC per hour.)

The self-consumption would be no issue if the elite 30 V2 would only PV load,
in case that the PV input is higher than 4,5 Watt.
But the elite 30 V2 wakes up in stand-by modus with the very first sun light in the morning,
not reaching at least 4,5 Watt. In those first hours of the day, until sun rises high, I loose energy
more that I get by PV input.
And, the elite 30 V2 will not turn off automatically when the sun light is away in the evening.
If you just leave the elite 30 V2 at your base camp while you are on a trip over night,
it will PV load the day over, yes, but then not turn off at the evening, and loose a lot energy in stand-by over night. It only shuts down when you reach 100% SOC, which will not happen every day with less sun light.

So here are my asks of improvements:

  • Could you add a feature to set the detection of sun light to a higher level, so that the device will first start PV loading when you have a good sun light? ( For example beginning with 10 Watt )

  • Could you add a feature to make the device turn off from stand-by into “power off”,
    in case that the device has no input of PV or for at least lets say 30 minutes?

  • Could you add a feature that you can set a certain time frame, like you can do that with wall power,
    in which the device wakes up in stand-by, starts loading PV, and then reaching the time frame end,
    stopps loading PV and turns off in power off mode again?

By the way, the app and the device itself is absolutly amazing to work with and I am pretty happy with it.

Thank you very much!
