MK2 Interface and Venus sharing VE Bus on MultiPlus Compact Inverter

Hi

I have an existing application which 'talks' to a Multiplus Compact inverter through an MK2 interface. I now wish to connect up Pylontech batteries UP2500. This requires connection of a Venus GX to the same VE Bus that hte MK2 currently uses.

I noticed from the documentation that the VE Bus is an RS485 bus capable of daisy chaining. Also, the devices on the VE Bus are addressable. Is it possible to connect both the MK2 and the Venus GX to the VE Bus of the Multiplus Compact at the same time?


Thanks in advance

as far as I know yes just move the MK2 to the other VE bus port on the venus device, or the other VE Bus port on the Multiplus as each have two ports

Hi Paul


Thank you kindly for the prompt response. I now have this up and running but the Inverter stays in charging mode. Should the device connected through the MK2 still be able to control the inverter?


Thanks in advance
