What happens when a consumer buys three and sticks them on the same 20 amp circuit? Cause people will definitely do that. Going to be some warm walls.

  800W peak * 3 is only 2400W which is fine, it's very unlikely to be pumping out that for long. Now if you put in 6 of them you will have problems, but this is the same problem as people plugging in multiple loads, and circuit breakers handle this fine in practice. Perhaps the bigger risk is a mix of loads and supplies on the same circuit, which could result in large currents on runs without a circuit breaker. Cheap extension cords are are possible problem too. Arguably the plug in PV should have to talk to a house bus controller, which controls generation and loads. Unfortunately the standardisation process is impossible.

    Right. The problem is the kitchen outlets or some other heavily loaded circuit. Running the microwave and kettle and fridge. And powering via these plus the wall. Or putting three of these on an extension cord.

      Where do PVs work best? Since you can't put them on the roof, out in the back yard. So you run a long extension cord and plug them into a power board. Or in an apartment, there might be one circuit with an outside outlet, so they all plug into that. Usually it isn't sunny enough and the load on the circuit isn't large enough, so the wiring will be fine. But sometimes it won't be. It's amazing that we actually have an IOT use case and the resistance to networking equipment is profound.
