> Will these “guerilla solar” units that plug into a receptacle to back-feed get approved for use?

They are approved at up to 600 Watts in Germany, and that will probably get increased to 800 Watts soon. You can just plug the inverter output into an outlet. This is called "balcony power plants" here, and lots of municipalties are subsidizing it currently. You can't get net metering, but you can offset some of your load with minimal cost and paperwork.

Why no net metering? Is the output too low to bother? I get net metering is not great for various reasons, but why 'discriminate' against what kind of setup it is?

Probably too expensive to replace the meters (only very old meters actually run backwards).

And 600w is probably below the average usage anyway.

Sounds reasonable. Here in NL, everyone must get a new smart meter that has a separate counter for delivering back to the grid. IIRC, the grid company replaced it free of cost, if done before some date.

The old ones (Ferraris meter?) just ran backwards, which is attractive of course. Our new meter has a P1 port which can integrate into eg. Home Assistant
