Mppt and Inverter Charger combination

Please be gentle newbie on site :pray::pray:
I, have been let down by voltacon and there 8kw inverter,
So am now going with the best
I need help to get the right system in place and seek advice
I am confident to install but get confused by numbers (autistic)
I am totally off grid
Currently have 7400 watts, of solar up, 2 x 8,panels
2x plyontech 5000, 48 v batteries with two more incoming
A.6.5 kw diesel, generator with full breakers installed
I need to know what. MPPTs to buy and and looking for Round 8lw of power output, higher is OK
Also how does the cables from the MPPts connect to charge/inverter I assumes they attach to the battery terminals in the inverter?
I am used to small, DC installations in boats
IF it Can be described in school talk that would be appreciated
Thanks for any help given diagrams are good ,

Use a bus bar connect everything there. It will allow an easy addition of more batteries

There is no 8kw mppt in the victron range but you can use a few smaller ones. Maybe 2 x 250/100 mppts. You can run your panel spec through the online mppt calculator for victron.
There are diagrams and cable and fusing requirements in all the manuals for the components. But here is a basic flow idea the mppts can also use ve can for comms
