So I have been watching Wills videos for about 3 weeks now and learning from scratch about Solar. Bought an EcoFlow River and some 100w panels to start and love it. Now im wanting to Build a portable backup system for home AND my 34' Raptor RV (using 30amp RV plug).
Dilemma:
Im selling my house next year. I want to be able to take my system with me so i Plan on starting with EEL battery cell, prebuilt battery bank. https://eelbattery.com/LiFePO4-Deep...Power-and-Off-Grid-Applications-p4179235.html

and an all-0in-one system , thinking about this: https://watts247.com/product/lv6548...250v-mppt-bms-ul1741-built-in-wifi/?wpam_id=3

and panels that i will ground mount: https://store.santansolar.com/product/ht-solar-375w-72-cell-mono-solar-panel/

Note, I will use my smaller panels when travelling.

Idea is to install the battery/panel on a dolly setup to travel with my RV and also use it to setup in my garage for backup power.
I will be using this and expanding it after building my new home next year in a more permanent install.
Id like a 48v system for home appliances and would be expanding enough to run off grid which is why im going with the large all-in-one to do 240v in future.

Question is: What do i need to do to use a 30 amp RV plug :https://www.amazon.com/110V-Electrical-Power-Outlet-Box/dp/B001FCBAPQ (110v 30 amp) AND a 120v receptacle? Or should i just do a 24 or 12v system?

Thanks for the help in advance and sorry if my idea is rediculous. Im new to this :D

I build a 48v system for my rv it uses a 3500w AIO inverter. This is about the same amount of watts you would get from a shore power connection. Although in my application it makes sense to have this unit setup inside my rv I could have just as easily wired an rv outlet to the 120 output of the AIO and used it that way.

Thats awesome. I will be living from the RV while building the new home, so this would be perfect.
Its nice to hear real world examples. Thanks for the reply.
