how to connect 8 mppts to a managed battery bank via gx deice

Hi,

whats the best way to connect 8 x 250/85 mppts to a gx device that has a managed CAN battery?

I'm looking at using a ccgx,can i just buy the ve.can version mppts and have both mppt and byd can ports used at the same time? or should i be looking at using a octo GX and VE.direct connecting them?

Thanks Tom

okay, Thanks for the suggestion.

I just had a look at the ports on the Cerbo. am I correct that they have separate CAN ports one set for BMS from the batterys and one set for the VE.CAN from the MPPTs that have been daisy chained?

Thanks Tom

There are two separate CAN interfaces, BMS-CAN and VE.CAN. Each has two RJ45 connectors to allow for daisy chaining or plug the terminator if end of line.
