Depends on how much current you need.  I'm planning to keep
my laptops, 12v B&W TV, camp lanterns and basic wifi
router/modem on line.    A full up computer with monitor
pulls around 100 W.   My minimal setup is much less then that.

Some day I'll have some nice generators, until then I have some
heavy cables with power pole connectors that reach the driveway.

(There - I said it.  Started the last power pole thread of the year.   Good
thing I didn't mention how I put power poles on a 50' AC extension cord.  :-)   )
