Backup battery storage vs. whole house Propane powered Generator

[chuck taylor]

A lot of people where I live spend $20,000 for a back up generator. We have frequent one to twelve hour outages and the frequency outages will probably get worse. Weather related outages last longer, and we could probably leave. So my question is what could I get to automatically switch to a battery back up that would run refrigerator freezer lights not Air Conditioning or electric heat. what could I get for around $10,000?

I run an inverter and some rack mount batteries to an interlock breaker to power my house, but it isn't automatic. It's a 20kWh system and cost around $6k after the 30% federal tax rebate for battery storage. You could setup a subpanel that can be powered by an inverter that passes through power and switches to battery when the grid is lost.
