This could help in some low density cases, but probably not in dense cities. It would require some changes to the inverters such that air con could still be powered in a blackout, due to anti-islanding concerns (feeding power into an isolated portion of the grid can cause injury to workers and further electrical faults).
An easier alternative for these rare cases is probably just to have a backup diesel generator.
- rjmunro 7y agoPower outages are not rare everywhere. Where they are rare, a diesel generator that is hardly ever used is likely to not work the time you actually need it. When the grid is working, powering your A/C from solar is still a good idea, and returning power to the grid when you don't need the AC is often helpful. In terms of emergency power outage in hot day situations, you don't need to cool the whole building, or cool it to a comfortable temperature, it just needs to be below a "wetbulb" of 35°C in a single room people can shelter in until power is restored.
