Ok here is my latest config based on current industry info.
Current specs / core cost.
(36) Longi 435W Bifacial Mono Solar Panel, ($6500)
(3) LVX6548 6.5kw unit for 19.5kw ($4200), (119lbs!)
(1) Aeon LTO battery A48=40 1.93KWh (40Ah), 22k cycles, 20 year mfg warranty, 80lbs, ($2968)
Looking like around $14k + my labor and good to go with this setup.
I tried to get away form battery requirement but no easy out. Looked at super capacitor solutions but hard to compete with LTO solution for high cycle / low maint / cost comparison
Would be nice to have a single all-in-one inverter vs having to buy 3. I am sure there are new models around the corner. Anyone know of anything coming up?
If anyone wants to advise different products, specs, etc I welcome your comments. Thanks.
