Hello all, I'm preparing to start installing my house RV system in my '96 MC 102 DL3 bus. I'll list the items I've already purchased, and my schematic I made.

6x 315W, 40V, 10A Qcell solar panels. - Running 2 parallel strings of 3 for 945W, 120V, 10A per string, to total 1890W, 120V, 20A into:
150V/35A Victron MPPT smartsolar charge controller.
2x Tesla battery packs, ~24V, 5.2kWh(233Ah) each. In parallel.
Victron Multiplus 3000W, 24VDC, 120VAC inverter/charger.
Victron BMV 712 battery monitor
I don't have it in the schematic, but I'll also be installing a BlueSeas ACR to tie the start batteries to the house batteries as the coach is 24V and has a HUGE alternator.
I've attached my schematic I made with google drawings, as well as the Victron example that I referenced.

I'll use 10AWG wire between the panels, to the combiner box, then 8AWG from there to the CC as it will be about a 10-15' run from the roof to the basement of the bus.

Looking for any feedback before I start.
