Should not be via a standard wall jack. As far as I know.
Depends on electrical code which depends on, most of all, your standard plugs. In Germany Schuko is deemed non-optimal, but acceptable, for up to 800W.
...no issues regarding exposed prongs, if the inverter doesn't see AC to sync to it doesn't output anything. It's not a dumb spinny magnet generator we're talking about here.
Most people don't have an outlet on their balcony, though, and weather-proofing the thing is an issue in any case so while you're at it you can just as well put in a proper Wieland outlet. 20 bucks or so, the expensive part will be the electrician not the outlet.
In the UK our everyday plug is rated for 13A - nearly 3KW. The plug on my phone charger is the same as the one on my tumble dryer and I don't know if that's a good thing or a bag thing.
Schuko is rated for 16A continuous for one hour, 3680W, I think the UK plug would actually take quite a bit more you're just being conservative. Or something odd about ring circuits I don't want to think about.
In any case practically nothing in a household actually uses 3kW. A stove, yes, but that's connected to three phases and without a plug (usually 3x20A over here -- CEE plugs can do that but they're chonkers and how often do you move your stove). Newer dryers should stay under 1kW, the standard high load appliances are kettles and hair dryers.
Eh, that's pretty standard where I live. Didn't even know there were non standard wall jacks lol
If it has anti islanding at least it's unlikely to be a shock hazard.
That said are there any other concerns I'm missing?
You don’t want to be sending current up into the grid while workers are repairing it during a power outage. If you just plug some shit into your bedroom outlet, that will happen. You need to disconnect your house from the mains. Whole house generators are old news, but no, your bedroom wall plug isn’t rated to power your whole house, and no, you aren’t just electrifying your own wiring if you try to do so. Whole house generators aren’t hard but they aren’t this easy. And you should be suspicious at how magically simple it sounds to just plug a dynamo into your wall to power everything. It’s the kind of thing we would love to be true because it’s so elegant but there’s a little more to it.
This particular product says it's 800W max. Most residential wall outlets installed in the last 30 years should be able to handle that (in the US). Also, it's a product only available in Europe at the moment where they do 220 through the wall, so less than 4 amps which is stupidly low.
Yes, being able to power your whole house through a single outlet is insane. Unless your house draws less than 800W
That's what anti islanding is.
Prevents power from going into the grid when it's down.
Way I read it is it puts surplus into the grid to keep you elec bills down.
800 watts isn't exactly going to set an outlet on fire.
