ESS with 2-wire BMS and MPPT

Hi,

In a system with a Multi 2, SmartSolar MPPT and a 2-wire BMS will the MPPT stop charging as well when Multi is asked to stop and the same goes for charging on low battery signal from BMS ?

Yes, EES reason code #3 will show - "BMS has disabled charging". VE.Bus BMS menu will show "Allow to charge = No"
MPPT's will support loads, but charging current to the battery will not be allowed.
