Emergency Lighting

[Mortblanc]

I visit several of the "narrow boat" forums and find that those results are pretty standard for them. They are off grid eternally and during the winter they can not hang enough solar panels on top of their 6'x60" floating abodes to keep their battery banks charged.

They are constantly complaining about the need to run their engines for an hour or two daily to keep the batteries at a level where they can use their lap tops, and a lap top does not use much power.

Lights and the 12v water pump are their only daily uses of power other than their computers.
