My question referred to the Multiplus-II not communicating natively with the JBD BMS. I'm not willing to buy a separate laptop to run VenusOS and a separate program to operate the Multiplus-II. I then asked, as I will not use AC charging, if the Multiplus-II needs to connect with the BMS or can operate independently of it. And if not I will go another route.
The Multiplus-II-48v-120v is indeed now available and shipping but that is totally independent of my question.
Part Number: PMP482305100 Note: To do advanced Inverter configuration and setup you must have a VE.Bus To USB MK3-USB Interface.

I'm sorry for the confusion.
