Not yet. Backup generators have lifespans in decades and cost less than $1000 per kW of power with energy only limited by fuel. What will the batteries be charged by when some huge storm makes it cloudy and rainy for days? Batteries as a backup power source sound great until you have to depend on them and they run out.
Batteries plus solar to run some led lights where there is no utility makes perfect sense though.
- Brakenshire 9y agoI wonder what the state of technology is for this yet. Most existing battery and solar installations can't be used when a blackout occurs, to protect the safety of workers rapairing lines. Seems like a bit more work needs to occur to be able to isolate the house from the grid, and then run the house system in isolation.
- snowwindwaves 9y agoThe problem isn't that the technology doesn't exist, it is that it is expensive to purchase and install. Automatic transfer switches will switch a load from utility to backup source when utility goes bad and tell the backup source to start.
