I live in an area near Seattle that experiences frequent power outages and my home is wired for generator backup. My home actually came with a portable 6000w generator but it hasn't been run in 10 years and the engine needs to be rebuilt so I'm holding off on that project..
My options are to go buy a new generator, one that will put out a lot of fumes, noise and need gas or propane every 8 hours.. or spend thousands of dollars on a dedicated natural gas system. Or buy a portable 2000watt 120v-only setup and only do the fridge.
I could connect to the Leafs 12v 80amp system and get about 700watts to maybe run the fridge, no.
I have a 24kWh 400v battery sitting in my garage. What I really want is a product that has a DC quick charge connector on one side, and a two pole 120/240v 30amp twist lock on the other side. It would ideally have 20A per pole up to 4800 watts. It would generate it's own 60hz 2-pole 240/120v inverter power, and I would plug it into my generator outlet, throw the switch-over breaker and my house has power in the power outage.. I would avoid running the elecric dryer and the electric stove, vacuums, etc but furnace, fridge, lights, computers, bathroom fans, all still work.
Anyone want to start a kickstarter with me? Or has this already been done?
