You can of course insist on on installation solely through a licensed technician, which renders the whole idea of small solar completely uneconomical. Rather than a ROI of less than two years.

And I wasn’t talking about a house fire as a result of violating the code limiting feed in to 800 Watts. I was talking about a house fire for entirely unrelated reasons, and insurance using that as a pretext of not paying fire insurance.

But the current 800 W feed in legal limitation is based solely on a worst case scenario. You can feed in safely a lot more if you are aware of the technical reasons for the limitations. That insurances always not want to pay out the claims and are highly creative in that regard is an accurate and fair statement.

I would go DIY and start with a bunch of panels (I have 2 kWp) and decent microinverters which are daisy-chained and feed in directly, preferably on its own circuit branch with decent wire crossection and a dedicated fuse. You can add a battery solution afterwards. It can get a little complicated.

Notice that if you’re not compliant with local law the insurance will use that as a way to weasel out of liability in case of a house fire.

Lots of these things already in Germany.

Thanks, that direct link works. Probably image replication issues to the other instances.

Images don’t load for me.
