Here are the requirements:
800 amp-hours of LI with nominal 48 volts
1600 watts of panels with a PT-100 Magnum charge controller
4400 watt 48 volt Magnum hybrid inverter/charger
A 48 volt dc to 12 volt dc converter to handle the 12 volt needs.
Nice but none essential:
a 48 volt element for the water heater to use up solar on those days when the air is not needed.
A back up generator--with the hybrid inverter even a 1000 watt generator could power the roof air--but I'd probably go with a 2000 watt.
enough unshaded roof space to install the panels, or create a roof rack that goes above the air conditioner shroud so the panels are totally unshaded. Tilting would be preferred.
