Background
I'm having a new 5th wheel built and as part of that process, I'm designing and building the battery, inverter, and solar. I want to run as near as possible to 100% on solar for everything including A/C while boondocking (my new favorite activity). I live full-time in the RV (have been full-time for 2 years, RV'ing for 3). Since this is a custom build RV, I'm able to do things like tell them to keep the roof 100% clear of obstructions for maximum panel density.
The RV
2021 New Horizons Majestic 5th wheel - 37 feet. I'm modeling the floor plan after this 40 foot design: https://horizonsrv.com/custom-rvs/majestic/40-ft-majestic-m40rk4s/
The batteries and all equipment (below) will live in the heated basement (I'll rarely be in cold enough weather to worry about that -- rather, I'm worried about heat buildup. I'm currently working with them to design a way to thermostatically vent the basement as I suspect it will run hotter than I want).
System Specs
I've received 7 of the 9 boxes (I ordered 36 cells, so I'd have 4 spare on hand). The other two are due tomorrow and Friday.
Victron order was just placed and should be here inside a week.
Cables and other stuff I just ordered and will arrive throughout the next week or so.
I'm currently sitting in my to-be-sold RV in my parent's driveway ("mooch-docking") and using their basement as my lab / build area. I'll get everything built and tested etc before I bring it to Kansas to install in the RV when I pick it up sometime in February. Logistics are totally up in the air at this point - but that's the general idea.
Right now, I'm toying with how I'll connect everything to the cells. That's the next post which I'll do in a few minutes.

System Specs
- 4+ kW solar (TBD)
- Victron SCC's (TBD)
- 2 5k Victron Quattro operating in split-phase
- 28 kWh of battery (2 14 kWh batteries - each made up of 16 280Ah EVE cells from Shenzhen Basen via group buy here)
- 2 Chargery BMS16t's with 300A DCC
- Custom built battery box (similar to others I've found here) - mostly for compression and a place to mount BMS and battery posts
- 30k LG Mini-split (LMU30CHV) and 2 zones (9 and/or 12k each)
