Hi @ftrueck, Thank you for your observation and analysis. However, after our discussion, we believe this should just be a coincidence. Since the Bluetooth module and the PV module are separate, they shouldn’t be related. Could you please take a video, upload it to a cloud drive, and share the link with us to have a look?
Please note that if you turn off the Bluetooth module, Bluetooth will be disabled, and it must be turned on to use it. As for the issue of being unable to power off, it is caused by the automatic activation due to energy input.
I think it was not clear enough what I told:
- The POWER button of the AC200L does not react to pressing
- Bluetooth is activated in settings page of the AC200L unit
- Bluetooth connection does NOT REACT in this special condition
- AFTER disconnect of PV cable the POWER BUTTON immediately reacts and turns off the AC200L unit
I know that these are separate modules. BUT the mainboard does not turn off the unit while the PV cable is connected and Bluetooth does not work when the crash situation happened. As these crashes are random, it is very hard to do a video. Next time it happens I will try to make a video demonstrating the whole situation.
Just FYI, if there is any charge source connected (either PV, DC, or AC mains) then the power button will not turn off the power station – this is the case for all Bluettis.

Ah, now I understood. OK, that eliminates that connection. The bluetooth problem remains anyways.

What i forgot to mention:
- Bluetooth was turned on in settings, but connection to AC200L was not possible
- Turning off bluetooth and turning it on again did not change the situation
- Only after restarting the unit bluetooth worked again
Hi @ftrueck, Thank you for providing the specific information.
Could you try replacing it with another mobile device and testing? If you can provide a video, it will indeed help with the analysis.
Thank you, @hnymann, for your reminder and explanation. It is very helpful.

Hi Bluetti,
i too have the same strange grid draw during peak time in TOU, perfectly described by ftrueck, with only capacity loads (router/PC etc).
Would be awesome a firmware upgrade with a new custom UPS mode option to disengage GRID completely (like we do with a smart plug, but without that), keeping SOC LOW as threshold to re-engage GRID eventually. Think this like the option “charge from grid” but this time the focus is to block GRID completely until you reach SOC LOW.
I think many of us use TOU to bypass grid during the night and with only capacity load connected (eg: computer / router and so on), it’s clear to me that you can’t redesign existent hardware to better support this kind of loads, but i think you can introduce this new option for advanced users like us, what do you think?
Regards,
Luigi
Hi @luigi_tomaselli, We would like to confirm if your power station is the AC200L as well.
Your user experience matters a great deal to us, and your feedback is highly valuable.
Rest assured, we have formally passed your opinions to the R&D team, who will review them when optimizing product performance.
Yes, AC200L.
Regards,
Luigi

@BLUETTI_CARE it really would be great benefit to be able to control the grid-ac relay via app/bluetooth. If your hardware designers were smart they made it controllable via firmware. Then this would be a no-brainer.
