Multiplus 12/3000/120-16 and CerboGX with LiFePO4

On my boat I am upgrading the electrical system from AGM batteries, 16 year old charger to VICTRON with LiFePO4.
For this I have already installed a CerboGX with MPPT for Solar and this winter I am going to replace the old charger and the old AGM batteries with LiFePO4 2x 280aH 12V batteries as well as the Multiplus 12/3000/120-16.
In the description of the Multiplus I cannot find how to connect the Cerbo with the Multiplus, as I only find two RJ45 connections for a Remote, which I do not plan to buy.
Is this even possible?

Hi @ObiOne

Of course it's possible. Those RJ45's in the Multi are VE.Bus, not to be confused with Ethernet or Can. Maybe you haven't found the manual yet?..

I've always said that Victron comms are somewhat challenging, but you get that with the best. Great choice, you'll love it once you get past the minor detail.. :)

I found that, I was just puzzled, because the manual of the Multiplus does only talk about Remotes, but not about Cerbo or a network functionality. But perfect, then I planned everything correct. :-D

I saw the same thing. The manual only mentions remotes, not that these could be hooked up to the VEBus. It does show up when I plug one of those ports into the VEBus. but it appears that all the features are not available. I'm worried I may have to buy the interface.

But all the cables are the same, right?

VE.BUS, CAN.BUS, Ethernet -> all RJ45/CAT6 cables?

Yes, all just straight too, not crossover or anything exotic. But use quality ones..
