There are startups, from austria for exmaple, where the panels get connected to some directioning device or inverter, and that device gets linked to a battery/storage and gets plugged into a usual wall mount already existing everywhere in the apprtment/house, a usual wallmount where you usually get electricity out off, you have your TV and PC connected to it for exmaple. But here, the direction gets reversed, you do not drain power from the wallmount, but you stuff it into the walmount, from the solarpanel and inverting device and battery into the circuit of your house cable circuit, and then you have it available at other wallmounts on the same circuit. Its a plug and play solution, and is simple to attach indeed, you have the panels placed, connected to the inverter or what the device is, the device goes to a battery, the battery to a wallmount, and thats it.

I did not believe it, too, until i read about it this weekend.

Question is whether the economic usabilitiy and the costs for especially the battery, calculate well.

I look for something smaller, maybe. I have no electric heating and electric hot water, am more interested in beign able to reliably recharge batteries, maybe run a refrigerator, or just a light bulb or two. So I more likely am looking for a setup like this: solar panel to a cable-connected mobile battery with inbuild inverter (if that is how its called, I am not sure, the German word is I think Wechselrichter), and some mounts in it for various plugs.

In Austria you can feed back 500W into a wallmount and circuit legally, in Germany 600, and an EU norm even mentions 800W. However, in this case you need to repalce your electric meter if it is a Ferraris meter with rotating disk in the display, becasue that disc would start to rotate in opposite direction if the solar device/batter starts to feed into your circuit. Since these solutions due to thew battery are already a bit expensive (2000-3500 Euro), the costs mount up if you want to replace the electric meter as well.
