In this thread, I'm looking to get the juices going and see what people thing about the ideas below.
According to the manual, when using internal bus bars, the maximum number of EG4 wall-mount batteries that you can connect to a single 18Kpv is three.
The reason for the limitation of three on the internal bus bar is that there are simply not enough ports.

However, you can use an external bus bar to connect more.

A client has asked for a proposal to provide (4x) EG4 wall-mount batteries and a single 18Kpv inverter. In order to support this configuration I have devised a rough schematic of how I would create an external bus bar, using a Victron Distributor.

My question is, do you see any issues with this configuration, and if I theoretically wanted to expand the batteries to 8 on a single 18Kpv would it be as easy as doubling the Victron Distributors by connecting them via their back-planes?
Hoping to get the juices going with some ideas and feedback. Much appreciated.
