BYD Battery-Box Premium LVL 15.4 showing 325Ah instead of 300Ah on CCGX

Hi,

I have few problems with my ESS system and BYD Premium LVL.

1. Capacity reported on CCGX (v.26.3) is much greater than 300Ah (see attached photo) ccgx-byd-caperror.jpg

2. I am no longer able to upgrade the battery box and BMU firmware using the latest BE Connect application (v1.7.1). I am able to connect to the battery wlan, after downloading the firmware in my android phone, but the BMU is busy asking to try again later.


Please help!

Thanks,

Mihai

Hello Mihai,

Regarding the update, could you confirm what is currently the BMS/BMU firmware displayed by the battery app?

If you have trouble with the app, try the BCP in a computer: https://www.eft-systems.de/uploads/b2b/2021-03-11%20Be%20Connect%20Plus-V1.5.0%20with%20Guide(1).zip

Alternatively, if it´s connected to the internet, we could do that remotely.

Thank you so much!

I will run the software tomorrow as I am no longer on site.

Software version reported by the Control Color GX is v1.20


Have a nice evening!
