  • Hmmm, I’m not an electrical engineer, and really not a line worker, but I do workplace safety for a living. I was sure you’re wrong, but it is indeed not listed anywhere in the sector’s risk inventory here. I stand very corrected.

    There is a generic “Make the site safe from both ends” risk mitigation though, and it makes sense that you take the same measures no matter what the source of the potential risk. Doesn’t matter if the cause is “all the solar panels” or “Some absolutely moron did things wrong several decades ago” or just plain “shit broke yo”.






  • And also why they shut down without powet in the socket.

    All solar systems do that, which is a good thing! It prevents lots of dead powerline workers. But that’s not the only reason, solar converters need to “tune” their AC frequency to that of the grid. No grid? Nothing to match. No power.

    It’s also why, if you want a stand-alone system, you don’t just need a really big breaker between your house and the grid, but also a different type of converter entirely.


  • One big problem with plug in solar (or batteries) is that they deliver more power than should be available, behind the fuses.

    With an 800W panel, an appliance could draw about 3.5A more before tripping the breaker, which can cause problems.

    It’s not very likely, but it’s also not the case that governments are just reluctant for no reason. These things being installed poorly is also quite a problem, Germany has had more than a few smashing down from a balcony.
