Let's do this.

@pfriedma Yeah, the system my neighbor used was similar but the back feed generator interconnect was to select the locally generated solar and wind resources, fall back to the grid power as a source, or use grid power as a sink, and that was *mostly* automatic, and using contactors. Knowing how that system worked is why I'm looking at this plugin PV and thinking the only saving grace in terms of fire safety is that it's 5A.
@BalooUriza
Yeah the constraint of "at least half as much current as the smallest likely breaker" is doing heavy lifting for fire safety... In the US it would have to be either like 500w or the "plug" would likely want to be a 5-20 to prevent you from e.g plugging a 20a supply into a 10a circuit (though even in this case the inverter could detect a overheat condition based on change in resistance and trip...I don't know that I'd trust just that if I had particularly flammable wires like knob and tube in walls with blown insulation) -

Maybe I'm paranoid, but I'm not letting any equipment designed with an energised male power plug into my home. If you want local generation, you have a professional wire it into the breaker panel with lots of warning labels.
Then again, my balconies face east and west and the sun hasn't been above the tree tops since October, so I'm not exactly in the target market anyway.@creideiki OK, good, so it's not just me and my NEMA-style wiring idea of electricity that's making me squeamish to this idea, since I need a little more than "trust me bro" on "things that'll kill me faster than an Oklahoma ambulance shows up"

@BalooUriza
I think the thing to remember is that the plug isn't actually energized the way you're thinking. It plugs in as a consuming device *first* then "negotiates" then pushes power back. When unplugged it's not still live, it's like you unplugged a TV.

I mean, look at the tropical paradise of Portland, Oregon: The light rail trains, rail/foot/road traffic signaling systems and the street lighting on the central transit mall (several kilometers long and two blocks wide, a couplet) is powered exclusively by a single SW-into-a-hill solar array and battery station.

@creideiki Realistically that thing's never going to ever see direct sunlight before 10 AM or after 7PM in the middle of summer, and in the winter it's only gonna get thick overcast light from about 8AM to 4PM, and it's still powering all that. And this isn't a new install, that's like, 2006.

@creideiki @f4grx @balkonsolar @derdo@pfriedma Yeah that's still coming back around to "trust me bro" on something that's getting plugged in downstream of all circuit protection and provides an energized male plug.

@TechConnectify Haven't watched the video yet, but have you ever considered uploading your videos to #peertube? I think if anyone has an audience that would carry over pretty well to Peertube it's you. And one of the biggest issues with Peertube at the moment is a lack of high quality content and creators.
@techindepth27 @TechConnectify some previous videos were on peertube though a mirror :

@BalooUriza Portland is still 15 degrees south of me. The southernmost part of Sweden is pretty much at the same latitude as the southernmost part of Alaska, and my latitude is within easy driving distance south from Anchorage. -
@TechConnectify If you put some sheep on the solar farm, you don't even have to mow the grass.

@TechConnectify I was curious how a one-and-a-half hour video about solar panels is on track to hit a million views within the first day.
Now I know.
-
@TechConnectify I just finished watching all the way to the very end of this video. I have a lot of thoughts, but at least the instance I am on has a character limit.
TLDR: I think this is a great video that is very informative and brings up a lot of good points especially at the end.
About the partisan political section in my experience there is a lot of dehumanization and not trying to have empathy for other people going on. I will do my best to get the people I know to think about others.
-
@TechConnectify this is your best video yet. The most important, too. Good job, Alec! Nay, brilliant job!
-
@sheddi OK, but where's the breaker that guarantees that?
@BalooUriza
If your question is "where is the device that guarantees the inverter cuts off if it loses connection to the grid", it's internal to the inverter. All grid tie inverters should have this function.I don't know the detailed German spec for these things but the British one is Engineering Recommendation G98.

@TechConnectify Really well done. Thank you for making this and sharing here!

@TechConnectify So a few clarifications nobody will ever read: 1. Hydrocarbons are dead trees which are renewed but very slowly. The tree is the best solar panel with integrated battery. Just takes say 100.000 years to renew. 2. You cannot replace organic energy with metal energy, because you cannot create metal from scratch without coal, oil and gas; and recycling it is only partly a solution. 3. Nuclear (and fusion) is just boiling the planet with atoms instead. 4. The real problem is food.
Nope.
1. The tree is 4% efficient at best, compared to 25% for cheap solar.
2a. Yes you can. See chemistry.
2b. Aluminium is made with electricity.
2c. Arc furnaces exist.
3. Irrelevant imported argument
4. More than one problem can exist at the same time.D-
see me after class. -
@TechConnectify This was fantastic!!!

@TechConnectify really well done!

@TechConnectify Tech nerd UNLEASHES on politics. Hell yes.

@TechConnectify Thank you so much for making this video. The world needs it so much right now.
