Hello,
Below are the setup,
Multi 24/3KVA/70A
2 x in parallel Lithuim Smart 24/200Ah
MPPT 75/15 : Connected with 2 x 115W Panel
MPPT 100/30 : Connected with 6 x 195W panel ( 3 in series; 2 string in Parallel)
How we can setup above items with VE. BUS BMS.
Have tried with Multi with BMS its working fine.
But what is the procedure to connect 2Pc of MPPT to control the charge.
The two MPPT units would be connected to the VE direct ports at the back of the CCGX
I don't see a CCGX mentioned. But yes a Venus GX or Color Control GX would be the way to connect everything together
Question was how to interconnect TWO MPPT to VE.BUS BMS .
( Topic was not about communication between CCGX and MPPT)
I'm sorry is the question about connection two instead of one MPPT's? or generally connection them?

Considering this post is now over a year old, I'm assuming you figured this out. For the benefit of other readers, the correct way to connect the above components (without the addition of a GX device) would be to connect the VE.Bus BMS to the Multi via VE.Bus cable. The MPPTs should feed into a Cyrix Li Charge smart relay that is isolated via the charge disconnect output of the VE.bus BMS. Likewise, on the load side, you should use a Battery Protect (a Victron Solid State relay) between the batteries and all DC loads. The battery protect isolated the loads via the Load disconnect output from the VE.bus BMS. Here is a schematic from Victron detailing a similar system (although this system uses a GX device).
Additionally, it should also be possible to disconnect the MPPTs directly from the Ve.bus BMS if the MPPTs have remote disconnect terminals. These can be connected to the Charge disconnect output from the BMS.
