Hi, looking for some advice on lithium drop in replacement house batteries...
For context, house came with a massive lead acid battery bank and they have seen their time and have finally hit EOL, approximately 8 or 10 years later.
Currently have on paper 35kwh of capacity, 4x12.8v 172ah batteries in series, x4 of those in parallel.
Knock that down to 50% DOD, so useable around 17kwh, more than likely less as batteries are FUBAR.
Facts for quick reference:
2x 5kw inverters in parallel
~3.8kw of solar panels (just a correction here)
Wind turbine, approx 150w, but varies greatly.
Evening use of around 1000w.
(Yes, quite high, but 2x desktops, fridge, deep freeze and a few other things add up rather quickly.)
Pool pump is already a 72v solar pump, geyser is also solar, gas stoves etc.
Aircons etc will be turned off automatically during loadshedding using a sonoff loadshedder, allowing for some automation of non-essential appliances to be disconnected.
Looking for something that does at least 6000 cycles at around an 80-90% DOD, with the option to extend to 20kwh (4x batteries) in the future.
Current plan is to install 2x 5.1kwh lithium's and upgrade later.
Any specific products to stay away from? Dyness are looking like a good cost effective option?

Any advice or recommendations on installers and products would be welcome!
