I have an SMA system with SI8.0 coupled to AC with sunnyboy managed by Emus Bms.



I recently purchased a victron 150/45 mppt at a much lower price than SMA's SIC 50 and Midnigt, for DC charging in order to achieve higher current charging,

Only charging with SI8.0, limited the charge to 100A.

I know that the MPPT Victron has no direct communication with the SI8.0h-12, but.eindefini to finish loading below the SI.8.0 and it has worked well.



I see the entire load on the BMS through the PC, but I would like the SI to show the total load (AC + DC) directly or through the links (local or romoto) so as not to hit me. I move all the time to the BMS with the PC.



SI has the possibility to add a shunt. There is a specific place to tighten the cables on the SI for it to read the current.



a 500A 50mv (bmv) shunt to guess the system.



The questions:

Will adding the shunt show the SI current load (from SI and MPpt victron)?



In this situation the SMA SI8.0 h-12 will likewise limit the load to + -100A? Or does it add up the entire charging current?



It would be good if someone from experience could anticipate the behavior.



Thank you
