Victron Multiplus 3 phase system simple diagram

Hello dear community, I have created simple (very simple) scheme of my planned victron 3 - phase home system. My questions are:

  1. Can I use only distributors or I need something else? or this is good as it is.

  2. every connection to busbar(distributor) is fused with fuse, is this ok? or should I also use fuse somewhere else? or somewhere not to use and is only optional?

  3. cable length from batteries to distributor will be original pylontech 2m cables (each battery has its own cables), this is ok or something wrong? I know wiring like this has more cables but each cable is rated at aroung 100A and so if I use more cables I didnt see anything wrong with it but correct me If I am wrong.

  4. Cables from distributor to all 3 inverters have to be same length or not? (for my opinion same length have to be from distributor to each inverter separately only) so first inverter has 2m (both + -) cables, second 1m both and third 2m both. This is ok?

  5. I saw installations where cables from MPPTs were stacked together in busbar (one eye on top of another eye and bolt together) so this solution dont get much space in busbar, is this also ok or something not recommended?

  6. I didnt use battery breaker on + side of cable because many ppl dont recommend them as they are can be source of heat and more connections, resistance, not reliable(many reasons)… Is this something mandatory or only option to use them (to have installation without them)?

There is no communication cables in diagram but of course they will be there :slight_smile:

For this whole installation and wiring - it will be done with help of person with electrical skills but as there are many options how to install and how ppl do the wiring I want to be sure for right procedure (what to buy, what is only option and mandatory).
Thank you for answer

I have between the battery to the distributor an on/off switch like this
Or this one but then with a fuse is also recommended.

Greetings
Palermo
