complete build, good setup? questions

hey I have done lots of reading and phone calls, and decided to go with viltron Lifepo4 batteries if I can get a bulk deal on them. also, if the 15% off coupon I have is still valid.

if not, I will be going with this build and would love your thoughts, since its my first real complete build from scratch.

I have 850w 12v solar on the roof of my rv, and mixed and matched stuff to get a good setup. battle born sells 'kits' that save a few bucks, and I was able to actually pick out a great one so long as I buy a few more batteries with it. the kit itself comes with 5x 100ah lithium drop in batteries with built in BMS, a victron 150/85 mppt charge controller, and a victron battery monitoring system.

this is the 'kit' ill grab, plus 3 more individual batteries totaling 800ah 12v

this is the inverter, I looked at outback but my setup is tiny vs that, not worth it

what do yo guys think, good setup? one thing I need to know is what to use for a 12v hub. obviously the inverter will power 120v appliances and everything, but I'm not sure what to get for 12v stuff. thank you all! heck of a summer. just installed my report halo long range wifi booster, two fantastic fan vent covers, and 300w more solar just yesterday :)

    Magnum Energy MSH3012M is most probably cheaper at Imarine. Same with the ME-RTR.

    If you are using Victron for part of the system you may wish to spend a little more and get a Victron Hybrid inverter/charger. You may find that by the time you buy a remote for the Magnum (which is required for the load support feature) that the cost is not very different.


    interesting. with this kind of investment, all things are worth looking at. thank you, ill be back later!

    you've been wonderful piano, thank you.
