Backup power–generator vs. ???
Working on a project where the owner would like a 20-kilowatt whole-house propane generator. Due to a variety of factors, it’s difficult to locate a unit of this size on their site, so I’m wondering now about other options for backup power. The primary issues they’ve raised are lack of water (they’re on a well, so no power = no water), loss of refrigerated and frozen foods, loss of communications, and lastly, loss of heating. Their house has a propane boiler and electric circulators, so only minimal power is needed to keep the heat on.
The two things that come to mind here are a whole-house battery, or perhaps an electric car that can be switched over to feed the house. I don’t know anyone using either of these strategies right now, but I know they exist. What is available and feasible right now, and if we fast-forward a few years, what might we see then?
