Hello,
I would like to get some feedback of the schematic i made for a small camper system.
The Smart BMS 12/200 looks like a nice "all in one" solution for alternator charging and BMS.
I used 80A fuses on the alternator side for a 60-70A charge..
The smaller DC loads and MPPT wil be connected to the System +, the Multiplus 12/2000 will be
on the battery side and disconnected in case of BMS alarm with the special cable:

I have read a lot of info here (not much info available for the Smart BMS 12/200) and seen webinars on alternator charging.. i think this setup should work fine.
A couple of questions:
1. If the "special" cable is connect from BMS to the remote port in Multiplus do i need to program
something extra in the Multiplus to make Charge or Discharge disconnect work?
2. Does the Smart BMS 12/200 work with all alternators? I have read Euro 6 with smart alternators
have a to low voltage to let the BMS charge full amp output say a 60-70A?
3. Some may say i need a (more expensive) BuckBoost DC/DC 50A, but i can't see the point in this if i can use the Smart BMS 12/200 as a "all in one" unit for this small installation?
Why would a BuckBoost be much better?
4. Could you guys check my drawing below for errors i may have made in this design.
Thanks much for your time and answers!
