Best asic with 5kw

Hi to all from Italy.
I am new in the world of mining.
I have a solar system with a surplus of about 5kwh and I would be interested in using it for mining. Can you recommend the ASICs available with a better ratio between initial investment and yield?

Do you have batteries or is it just excess while the sun is up?
I would look at Jasminer x16-P which is earning a bunch at the moment. There isn’t a halving coming up like BTC or CKB. Only 1.9Kw
I’m thinking about a Bitmain KA3 to give KDA another shot as again, no havling coming up near as I can tell and the massive hashrate flood from all the new models seems to have settled down so it might do OK for a while. 3.1Kw so if you are only up when it’s sunny it might be effected by the clouds.
