Comment on Easy-to-use solar panels are coming, but utilities are trying to delay them
artyom@piefed.social 7 hours agoIt has to be compliant with the local law to be sold legally.
So you can’t buy raw solar panels or inverters in Germany?
It all shouldn’t be so difficult to understand.
It’s not, which is why I’m not sure why you’re struggling.
Of course you can buy whatever you like, and whatever is being sold has to be compliant with local legal requirements.
If you buy illegal stuff and cause problems, you will have problems with your insurance and potentially, legal ones.
And that’s all I’m going to say on the matter. HAND.
There’s no way to prevent people from connecting perfectly legal equipment in an illegal manner, where otherwise there would be.

Sure you can. Solar panels will be fried by grid voltage more or less immediately if you connect them directly to a wall socket and become useless.
You cannot buy a PV inverter in Germany (entire EU really) that doesn’t automatically shut off if it doesn’t detect a frequency to sync against from it’s AC side, unless it can run off-grid in which case it has to disble the grid connection within the same 20ms.

So you can’t buy a grid-connected inverter with off-grid capabilities? Because the inverter has no way to tell the difference between the grid being off, and being off-grid.

Oh you can buy off grid inverters (or inverters capable of “island mode”). But they are required to be able to automatically disconnect from grid, even if they are never going to be connected to a grid. You can’t buy solar inverters without this for the exact reason that you can connect them to grid.

Again, it doesn’t matter what inverter you buy, they can’t tell the difference between off grid and grid off. So if it shuts off when it doesn’t detect voltage, then it won’t work off grid. Which makes it sound like you’re saying off-grid inverters are illegal.
