Multiplus 2 shut down with Pylontech

Hi,
I have a pylontech battery and the Multiplus 2.
I want the multiplus to switch to mains at a certain battery level, e.g. at 10% battery level.
However, the multiplus goes down when reaching about 12%.

If I set the threshold to about 13%, it usually works without problems, and only occasionally (once a month) does it go completely down.

I will try to raise the threshold to 15% to solve the problem.

However, I am interested, why the Multiplus ever goes down, if he should simply switch to mains operation?
Sends the Pylontech battery possibly a shutdown signal, because if I remove the CAN bus Cabel from the battery, the Multiplus does not go down?

Thanks in advance!

Are you using ESS?

Hello, no, I actually realized this with the standard interface of the virtual switch and in principle it works. Only this complete shutdown sometimes I can not understand.

here my configuration:

I think if you moved to an ESS system instead, this issue would no longer occur.

Thank you for the tip. The Ess system is now intalled, until now there were no shut downs!
