The real small units are 120V only, a normal transfer switch / interlock

furnace or other larger loads.

I could have sworn it ran my furnace for 5 days two years ago, as well as my
refrigerator and freezer.

It may have depending on what you have for a furnace. In many cases it
won't.

And in many cases it will -- really, the only cases in which it won't are
electric furnaces or heat pumps. The electrical demands of oil- or gas-fired
forced-air furnaces are quite modest, and those of hot-water systems are even
lower. A typical refrigerator requires much more power than a typical gas
furnace.


Remember, the EU2000i is rated 1,600VA continuous and 2,000VA for 30 min
max. In order to handle many of those furnaces you'd need to do load
management so the furnace was the only load at the time.
