thanks for the reply, I think I'm covered on the charge controller I bought this https://www.amazon.com/dp/B01MSYGZGI?ref=ppx\_yo2ov\_dt\_b\_product\_details&th=1
Hi,
I have not bought anything yet so this looks like a good potential option. I drew up a diagram of what I was thinking but don't know how to attach it here as a file (first time posting on Reddit).
This is the concept I am going for minus the alternator charging part:
These are the components I am considering:
Panels: x3 Renogy 100w 12v https://www.amazon.com/dp/B07GF5JY35?tag=skooliesupply-20&linkCode=ogi&th=1
Combiner Box: Eco-worthly 4 string https://www.amazon.com/dp/B07F5HDP2W?tag=skooliesupply-20&linkCode=ogi&th=1&psc=1
Solar Charge Controller: Renogy 40 amp 12v mppt https://www.amazon.com/dp/B01MSYGZGI?tag=skooliesupply-20&linkCode=ogi&th=1&psc=1
Battery: Chins 300ah Lithium https://www.amazon.com/CHINS-LiFePO4-Battery-2000-5000-Off-Grid/dp/B08N53GF81/ref=cm_cr_arp_d_product_top?ie=UTF8
Inverter: 2000w TBD
Shore Power Plug: 30amp
Auto Transfer Switch: 30amp in 30amp out https://www.amazon.com/dp/B00153EYTO?tag=skooliesupply-20&linkCode=ogi&th=1&psc=1
Converter/smart charger: Powermax PM4 60a 110v to 12v DC with smart battery charger https://www.amazon.com/PowerMax-PM4-100A-Converter-Battery/dp/B01ER3LGYY/ref=as_li_ss_tl?th=1&linkCode=ll1&tag=vc-electrical-20&linkId=d8548aa852a41b8ce022d573b5e907c1&language=en_US
Would this system all work together? Would that item you recommended be a better fit. I'm also considering getting a renogy inverter/charger/converter combo to do my inverting to AC from DC battery and also my converting from AC shore power to DC to charge battery but those are a bit pricey.
Open to all thoughts and recommendations of course.
Thanks!

Either of these controllers will work with your 3 panel setup at peak output in series. The Victron is a nicer higher end product, but the renogy unit will even handle a fourth panel at max output, though you'll have to go to a series/parallel mix on your panels to get it to just over 50v peak. The Victron would be sufficient for four panels as well but anything over about 360 watts won't go to your batteries, just something to keep in mind. If you get a fourth panel you'll have to do the same series and parallel mix on the panels for the Victron as well so you don't exceed 100v. If you ever swap to a 24v system in the future that will allow you to double up on your panels and double the wattage capability of your charger with both of these.
idk why I thought bigger was better with a fuse... obviously it needs to be sized to the same amperage as what can be pulled. thanks, ill definitely rectify that oversight...
as for the charge controller wrong terminology in my drawing i pretty sure I have an all in one

Well in that sense you are building your own setup.
Here's a 40 amp 12/24v MPPT solar charge controller. Let's say you are using 24v solar panels (or 2x 12v in series to get 24v)- at 24v, 40 amps is 960 watts. So it'll handle up to 960 watts of 12vdc power output.
You'd then wire that up to a battery bank of your choice. Could be lead-based (SLA AGM etc) or lithium based. It will correctly charge and maintain those cells.
You can then use its power output for up to 960w of 12v power. Or if you need more, you can attach your load straight to the battery and pull whatever the battery can supply safely (just add a fuse inline).
