Hi guys
Before asking anything I'd like to thank everyone for all the help and information that is provided on this forum, I learned so much thanks to you all it's invaluable.
I'm building my first battery and electric system therefore I would love some guidance on my choices of equipment. I already have an idea of what to get and where but maybe there are other more fitting equipment / sellers(or manufacturers) I should go to so if you'd recommend anything else please let me know.
This is all to be built in an RV, and I'm in France which is why the inverter is 230vac.
Here's what I'd go with right now :
BATTERY
24V system ( 48V seemed too much for the size I'm going but I could get lower amperage cells instead, dunnot if it would change much ).
CELLS
LiFePo4 230/280/302ah Grade A 230ah is the minimum, I can go for more if the value is there ( should avoid EVE's 280ah I believe )
EVE - CATL - CALB I don't think any of the manufacturer is better / more reliable then the others, comes down to the reseller I assume.
I'd go with Shenzhen Luyuan Technologie with the reviews I've read.

BMS
Jiabaida seems to be a good manufacturer, I believe having a 200a BMS won't be a problem if I don't pull more than 200ah and scale the system accordingly.
Their AP21S001 200a LiFePo4 seems to fit my needs.

CABLING
Sizing for 200a being the max current out the battery to inverter, the cables should be rated for 250a minimum, so going with 95mm² or 3/0AWG right ?
FUSES
A good class T ( 200/225A would do I believe ) just after the battery before the inverter, haven't looked from where I should get it yet. CNN or ANL ( they seem very similar ) for the rest of the DC circuit.
Should I go lower on the T class since the inverter won't ever be able to draw that much ?
For my DC appliances, are fuse block like ones from blue sea better than individually fusing every appliance?
INVERTER
My primary need from AC is a computer and that's it, I really don't need a powerful inverter so I looked for the least powerful ( and expensive ) and found this 3000w 24v Inverter/Charger/MPPT from MPP. Couldn't find any review about it, but they seem to have improved in quality over the years so I think it will be good.

SOLAR PANELS
Haven't looked into it but I should be able to put 800W on my roof, so getting the 70v requirement of the mppt should be ok.
Other Component
BATTERY CASE Not sure where to buy those, LUYUAN are selling some so maybe from them ?
INSULATION between the cells, what material should I use ?
FUSES for the ac circuit, I can't find much information for these. Circuit breakers seem to be the way to go.
SWITCH Should I use any ? The loss in resistance makes them unappealing.
That's about it I think, I tried to keep it short but ehhh.
Thanks alot for your time and knowledge, and if you care to guide me I'd be very grateful .
