Is My Installation Plan OK? (Pictorial)

[AgroVenturesPeru]

Is this ok?
What's the correct order of the installation?
Only thing I'm really sure is that I hook up to the mppt first with the batteries, and at some later point to the PV array.
my PV array is already wired and so is my string box...ready to plug in to the mppt. Oh and the batteries have off buttons.

Looks reasonable. Just make sure the batteries canbus is compatible with the Cerbo as not all are.

Also you need a terminator on the other BMS.Can port on the Cerbo, but not on ve.bus.

I also don't think you need the loop to the batteries, but it doesn't hurt overall. At they are all in parallel you can also run smaller wire from each battery to the bus bars as well.
