That’s an option - I’ve seen the setup in a couple of places. Utility goes down, you switch over to solar/batteries and remain that way until the utility returns. The only way you’re allowed to remain “live” is if you have batteries or a secondary power source, such as a generator.
The big issue is the cost and maintenance of the batteries. If you go lead acid there’s issues with space, storage and maintenance, as well as a limited life. The alternative is a sealed lithium ion system like the Tesla batteries, but they’re very expensive and also have a fixed life that will require replacing them down the road at some point. From what I’ve seen, when people are presented with the option the don’t pursue it due to the additional cost. -D > On Oct 12, 2019, at 8:16 AM, Jim Cathey <jim.cathey...@gmail.com> wrote: > > Most don't understand that the TRUE name of 'net zero' metering is > just an accurate description of what you get from your expensive solar > array when the grid is down. :-) > > What doesn't seem to exist are the electronics to push back to the grid > only when the grid's on, AND your storage batteries are full, and that will > run your house from batteries while the grid is down.
