I've always wondered, how does balcony solar work? Are you charging a large battery and using said battery?
That article says you just plug it into an outlet. Is it a special outlet of some kind?
I'm just one of today's lucky 10,000 and want to learn about it.
Actually it's quite smart and simple l: you take any outlet in your house!
The ac/dc transformer those things simply feeds it's energy into your house - after all a plug doesn't care in which direction power flows. .those systems have an upper cap though to prevent people from overloading the net.
It's really neat and simple! You basically lower your lower consumption by whatever these things produce.
I don't know or have seen anyone using these small balcony cells with a battery though - while technically not a problem I think there's simply not a use case: they don't overproduce that much at any given time anyway.
Holy fuck delete this shit. You've described a death plug, and this shit kills grid workers and innocent people who don't know the plug is live. You absolutely NEED a proper system set up for this with a PROPER PLUG and the proper safety disconnects to avoid backfeeding the pover grid and KILLING PEOPLE.
No, he’s not described a death plug. The inverters only produce was it sees the sine wave from the grid.
If the grid goes down, break trips, or it’s unplugged, then it stops producing.
Calm down.
It can only produce electricity if it measures the right voltage coming in, it needs to sync to the net. They don't work in island mode.
But this is exactly how they are designed to work.
I didn't say that you should diy this but the sets described in this very article works like I described.
Here's a random one with data sheets and installation guide.

Perhaps you should delete your shitty and wrong rant instead?
