I have Sol-Ark inverters that produce 18kW of continuous AC power for my home. I lose about 5% when converting AC to DC. I also have 92kWh of Gyll battery storage. I lose about 10% in the round trip to store DC power to batteries, then later retrieve that power from the batteries as needed (i.e. at night, or rainy days).
The end result is that my 20kW of solar produces 80% of the power my all-electric, 2,300 sq ft home needs, including charging our Ioniq 5 for 16K miles per year (not counting the road-trip miles we drove it and charged away from home).
My inverters have a feature to power a separate electrical panel intermittently. I have one of my EV charger circuits on that panel. We usually need the EV charged only 50% for the next day's drive. So if we come home with more charge that than, we'll plug it into the intermittent charger and charge the EV beyond 50%, but only if the power is free. If we come home with less than 50%, or if we plan a lot of driving the next day, we plug it into the constantly powered charger (which will definitely charge up the EV, but may or may not be free power).
That one simple charging habit works amazingly well at making most of our EV charging be done by homemade solar. We charge more on sunny days than we do on rainy days. And that feature wasn't available on Tesla Powerwalls back when I bought my much cheaper Sol-Ark inverters.
I think solatubes is also a pretty good idea, because you can light up your basement for nothing during the daytime.
