800w is less than half what you could pull from any outlet in the US. Standard electric breakers are rated for 15amp continuous at 120v. Most heating appliances designed to run for long periods of time (like electric heaters, or countertop cooking) run around 1800watts. So you could pretty easily plug in two 800w solar panels to back-feed a single circuit.

50amp 220v is about the limit on one circuit for most residential homes (for ovens, or electric central heating) which is what would be used for the fastest electric car charging at home.

That’s plenty of headroom for in-circuit solar generation.

You could when solar fist started becoming available. Energy companies quickly realized that if everyone did that, they’d have way too much power during the day, and none at night.

Our local co-op power generator barely makes it useful to have solar unless you also have battery storage.
