I'm the other side of the pond, but

tesla isn't great value any more. For a while powerwalls were the shit And the powerwall three is nice, with direct DC charging as well as islanding.

But, only 13kwh still, and internet dependency, and very expensive.

I currently have enphase micro inverters and a power wall 2. It was the right mix at the time.

But, if you have the space, which I think you do, An insulated shed for a 19" rack, and choose any one of the many battery unit makers. Its about $200 per kwh now (in UK prices, I'm not sure what tarrifs are doing for you)

then get a frame for your solar (or build a barn and roof it with solar, its cheaper than 12mm plywood at the moment.)

Have micro inverters, they are more expensive, but solid state, less likely to catch fire, do MPPT better, and are not a single point of failure.

You'll need backup for when solar doesn't cover your daily needs, so either grid or some other power source.
