I've been reading a lot about battery backups and this is a decent article that covers those plus standby generators.
@Shelter "The best system depends on where you live and what you can afford." ---This statement is near the beginning of that article. It perfectly encapsulates why climate change cannot be separated from Environmental Justice. The author may not have even realized it. Oh well...right now gotta take care of my own place. Thanks again for the article.
Yep.
However the key there is winter temps because some batteries will freeze.
@Shelter Thank you! Yes, I've already been poking around Generac and a few installation outfits' websites. I'll check it out.
