terrybeckley1,
Here is what I would want
as much solar as will fit on the roof
a hybrid inverter/charger that does "load support"
an MPPT charge controller that is adequate to the needs of the panels, one with diversion load capabilities, so that excess solar capacity may be used for water heating
a dc to DC charger to protect the alternator
a dc "hot rod" for the water heater
consider a 24 volt battery bank
use a heat pump instead of roof air they are more efficient.
let's see how many folks can add to this short list?
