Kenneth,

I wonder if a solar or wind powered charger would be sufficient for the
battery backup on the sump pump. 15-20 hours is quite good by itself, then
add to that changing from solar power during the day...should be enough to
keep the sump pump running intermittely for a long time.

Seems to fit -- I'm not sure I see the problem here... g

and I need a small fraction of that.

If all you really need to power is a sump pump and a small fan, then an
automatic backup unit seems to be overkill; is there a reason you can't
use,
say, a 1500-watt portable generator?

Consider a sump pump with an alternative power source, too, such as
Basement
Watchdog or Ace in the Hole.

Hi Doug,

I could use a small generator... In fact, I have, but...

We travel a fair amount, and living in rural New Hampshire,
outages are not all that rare.

We would be in trouble if we had an outage while we were
away.

Beyond that, the standard "battery backup" units for the
sump pump seem to have a run time on the order of 15-20
hours and I recall an ice storm in which we lost power for
more than 96 hours.

Thanks for your thoughts,
