BMS 12/200 with both alternator and solar charge sources

Hi there,

I'm considering a lithium system in a Sprinter Van using the BMS 12/200, with the batteries being charged by both the alternator (when the vehicle is running), and solar (when the sun is available). Obviously the alternator would be connected to the AB port and will shut off in overvoltage, etc scenarios. Should the solar charge controller then be connected to the LB port? Will the charging shut off on the LB port in an overvoltage scenario, but maintain discharging / power to DC loads? The solar charge controller in use would be the SmartSolar MPPT 100/30

Thanks!
