[RE-wrenches] Polar Power

[Ray Walters]

I've got one customer that has one, they're pricey, but seem well made.  
They had quite a few problems and are going to a regular AC generator 
setup and decent inverter/ charger.
The off grid solar biz has tried DC gen sets several  times, and it has 
never worked out.  The theoretical gain in efficiency is not worth the 
loss in reliability.
