New to Solar, New RV, Mega System (components recommendations)

[Jacob72]

Have good idea on main components and already purchased solar panels, so here’s what I have:
•50amp 46’ Jayco Seismic with tons of roof space.
•5500 onboard Onan Generator
•A.T.R.S. Auto transfer relay switch (PD52) for gen
•10- 500w Znshinesolar (ZXM6-LDD72) Mono Bifacial Double Glass Module. Planning on 2 strings of 5
VMP-40.8
IMP-12.11
VOC-49
ISC-12.63

Here’s what I want, or understand I need to power 90% of everything off-grid/ what’s missing or need to be changed/ recommendations:
•Dual Victron 48v 3000w Quattro @ $1856 each.
•according to BB I need 2 Victron 150/60 tr. $540 each but Victron’s website says I need 2- 250/60 tr. $640 each sooo?
•BMV 712 $230
•RV roof dual cable entry$15 for each side?
•Battery disconnect switch $22 (how many)
•Circuit breaker manual reset $15 (size, how many)?
•what else is missing other than wires which I have no clue on sizes.

My battery choice I’m leaning towards maximum ah and price so: $112 per cell ($5376) not including a quality BMS and shipping.

2 strings of 5 implies 5S2P or 250Voc - WAY too high. You also will be highly susceptible to shading.

Better to go: 2S5P

Single Victron 150/100 is good to 5800W. 150V limit (you're at 98V, but 3S is too high if it ever gets cold). It also has a 70A PV input limit, and you'll be at 12.11*5 = 60.5A.

In other words, a $770 Victron 150/100 will handle your whole array.

I'll be impressed if you can get that array on that beast. I struggle to fit 6kW on a 40' shipping container, and I don't have to worry about roof protrusions.

Unless you NEED dual AC input, you don't need a Quattro. The Multiplus is cheaper and is essentially the same unit. You'll wire the inverter between the ATS and AC panel, so the AC input is either shore or genny as the ATS dictates. It will pass through power and assist as needed.

You'll want a GX device to help manage the system and integrate the components.

A BMV-712 is only needed if you need a temperature sensor or starter battery monitoring and bluetooth access. You generally don't need bluetooth when you have a GX device as you can access it direct.

You'll need VE.Direct cables for the SCC and the BMV to connect to GX device. If you get the BMV-702/712, you need to by the temp sensor separately.

280Ah cells are selling shipped for about the same price as the 100Ah cells you list.

I got nothing else.
