Ooops, Sorry about that, The 1.920x10^3 WH on my HP Calculator
suffered a typo in transcription and became 1,920KWH.

I then managed to carry the K throughout the rest of the
calculations. DOH! I should know better than to try
such calculations before my morning caffeine dose!

It's good to see that someone is actually checking the
math.

At least I think I arrived at the proper conclusion----that
you only need to use about 133 Watts continuously to require
quite a large alternator to recharge your house bank in
4 hours. In tropical waters, you might reach that load on
refrigeration alone---particularly if you want ice in
your cocktails! ;-)
