Thank you for the comments. As stated, I do not wish, whatever the qualities of a proprietary solution, to go down that road or to have to carry or obtain expensive, single-sourced spares. Our focus is on a robust, no frills system with a moderate output, although I am becoming persuaded that a 20 gallon/hour AC-powered system may be more efficient than a lower-flow DC-powered system in that I could get a week's worth of drinking water during a two-hour motor (I have a pilot house and can use rainwater from a separate tank for washing and cleaning).

I agree that a nine-amp system has the edge, as this falls within the desirable range of both the Hondas and the inverter I already possess, meaning I don't have to rig an engine-driven setup with a dedicated or partially dedicated alternator.

Thanks to the CF Brains Trust for some illuminating information and great advice.

That is pretty darn efficient!
