thats why i say the one 10kw rectifier.then split it off as 120ac to everything.
probably the 48dc is best.im using 12dc on a well and a emergency lights thing.my well is shallow,so i just got a 12dc amazon pump.you dont need high volume,so why buy a high volume pump?
in the country,nobody needs a 300dollar pump unless its deep well.you aint in no hurry to wash dishes and those cheap pumpz will shower just fine.20$ goes a long way.
if i had the money i would be off grid too.im slowly building my system.
i got two very screwed lawnmower batteries on my well.like ten years old and acid replaced.they still hold 12.8.
those cheap blue solar controllers do great for my little op.

oh,most important,silicone wire grease!
best investment i made,use it liberally on all connections or fight corrosion forever.buy it,a big tube!
you will thank me later.
