Surely you can do what you want within your own home, so long as you don't hook it up to the grid?

I'm also not sure if this fits with the price restriction they mentioned. Prohibitions can't be bypassed by paying a higher price, unless it were to refer to bribes

The systems in the article are hooked up to the grid though.

They're hooked up in an extremely safe and responsible manner, but it's understandable that there are regulations about what can be hooked up, and simply not surprising that they haven't been updated to say "yeah, this is ok".

A lot of solar systems are set up to sell excess power back to the grid. It makes sense that these systems would have some regulatory criteria because you wouldn't want e.g. home solar systems putting power on the lines when the utility company has the power off because of a downed wire or active work.

It's also possible to have a solar system that doesn't do this. Either you have a battery system and if you generate excess power you only put it into your own batteries or the system is small relative to the load of the house so you're rarely if ever generating more than you're actively using and configure the system so the grid is only ever attached to the input side. This should not be any more dangerous to the grid than using a UPS or charging an electric car and if the regulations make it more difficult than that they should be suspected of malicious intent.

The systems discussed in the article aren't necessarily selling excess power back to the grid, but they are sending it back to the grid (possibly for free). Because they work by pumping power into a wall socket.

They do so responsibly (fancy electronics that turn them off when the grid goes down). But it is the case where you are acknowledging that extra regulatory criteria make sense.

But in that case the regulations would only have to apply to plugging in something that doesn't do that. There shouldn't be any forms or approvals or fees for someone who buys a product that does.

I agree there shouldn't be, but I don't think it's surprising that in many places there are. It takes active work for the regulator to look at the product and say "this design is sound, we're sure it won't kill anyone".

It takes active work to do that but not to manually approve zillions of individual installations?
