I made a mistake in my quote of the steady state current demand of our all electric air conditioning system.  It’s more like 50 A and can be as high as 60 A at higher temperatures.  So, this corrected requirement bumps up the power supply needed and costs considerably (~$1700).  Fortunately, Bob Pastusek has convinced me that I can provide continuous power with the battery set up and a powerful battery charger -- which is much cheaper than a power supply.  Having the batteries in the circuit will ensure good power quality.  Thanks Bob.
