And a fourth is, if you have a dynamic energy contract, where prices can change as quick as every 5 minutes, your energy provider can stop your panels from delivering power to the grid when prices are negative. otherwise you’d pay for every watt delivered back.
You can do this manually (as in diy, you can automate it with eg home assistant of course) with modbus on a lot of inverters, but idk how that works with these micro-inverters.
Energy suppliers have to buy their energy from the actual sources, of which there are a few here. They buy all the watts they think they’ll need based on a weather forecast the day before. If this forecast was rainy but now turns out to be super sunny, meaning lots of solar which can support the grid, there may be massive excesses of energy that now no one wants to buy. But due to the way an electricity grid works, this electricity has to go somewhere, so they sell it at a loss.

Why are power companies giving away free energy?
That’s how supply and demand works.

That’s how it works in the Netherlands, anyway.
