The Tesla Powerwall that is being installed here will automatically disconnect from the grid if an outage occurs. That way linesmen are safe to do their work.
I can see where that would be a problem with self designed/installed batteries. They may not have the line voltage sensing circuitry that things like the Tesla Powerwall do. If your parents want battery backup it might be worth checking with the utility to see what needs to be installed to allow it.
I have to check the local regs - they’re annoying in Canada sometimes… my parents have a really nice generator set up so they do have power when it goes out, but it would be handy to have a system for the solar panels that they allow. I feel like my father would have installed it if it would have been available at the time and something the local power company allowed - he generally keeps up really well with those things. Perhaps they will in the near future.
Thankfully the location in the photo above is 100% off grid and doesn’t have to worry as much about that.
