Default Electrical conundrum - mains aircon in motor home

(1) Run the A/C whilst driving - that would I assume involve an inverter
which could take power through the 12V electrics buffered by the
habitation batteries (unless the demand needs a direct connection to the
alternator charging circuit instead of via the charge controller which
charges the habitation batteries). This also allows starting the engine,
firing up A/C and then stopping the engine and letting the A/C run on
using the habitation batteries.


Vehicle AC is invariably driven direct from the engine - the compressor
via a belt drive, etc. You'd need a massive alternator to provide anywhere
near enough current. And a massive inverter.
