ECN Forum Forums General Topics of the Trade General Discussion Area DIY grid connect solar panels...safe to use?

I can't see how any device generating electricity fitted with a male cord cap could possibly be considered acceptable in any country of the world!
So... in my eyes no.
Edit: on the other hand grid inverters tend to have fairly complex electronics designed to prevent putting power into a disconnected line (so for example linemen working upstream in case of a fault won't get injured) so it might(!) be considered safe.
