ESS two instalation one works fine one not

Hi,


Why in one instalation i have Multi managed from external control and another with bulk ?

during installation 2, it doesn't matter how the charger is set on the inverter, whether it should stop charging at 30% or 95% ... the inverter was replaced and it has no effect ... what a magic :D

@Juraj Nikolov

Same firmware, same batteries? Same programming? Same firmware on the batteries?

It would seem on the bulk one the Pylontec is not the controlling bms.

You could check that in settings. If it is not that then swap the master battery.

In short the problem is because the battery has not taken control you need to find the source of the break on communication. There is a difference between the systems you need to find it as the installer.

I have said this because there is a smart shunt in the second system. And they both do SOC. So a conflict.
