What is the best way to connect Multiple MPPTs to Color Control?

Hello,

I have 4 MPPTs and 1 BMV and I want to add them to Color Control. MPPTs have also can.


Now, what's the best way to connect them?

- all via can and BMV via ve.direct

- 3 via can and 1 via ve.direct and BMV via ve.direct

- all 4 via USB and BMV to ve.direct

- all 5 devices via USB


My question is if I can mix connection (can, ve.direct and ve.usb) or need to add all on same connection type?

Second question: How many USB devices can add to Color Control max? I read in manual that 5 is max. processor can handle. If plan to add more MPPTs need to change my GX device?

If all your MPPTs have VE.Can I would recommend to use that. It's easier and cheaper to install.

I'm not sure if the limitations also apply to VE.Can.

@Matthias Lange - DE, thanks for answer. I not find also any info about limitation on can.

On many artworks its show that CAN connection can go up to 25 devices and is a photo of Color Control.

I have some issues with random MPPT that not start in the morning, it's show 0W even the other 3 MPPT with same panels produce over 300w each, and I was think that is because of the connection. That I ask if I can mix them in different connection types.

Mixing the different connection types is no problem.

If you hit the CPU limit you will recognise this by a slow responding interface and random restarts of the CCGX. You than should upgrade to the new Cerbo GX.
