There is a Switching unit available with a Load Drop Sensor, that Automatically turns on 220/240v Generators when you turn on appliances (eg: Hair Dryers, Food Processors) and then shuts off the Generator when you turn off the appliance being used.
This gives you the best of both 12v and 220/240v Systems running through the same Ring Main.
In use, there is only a few seconds delay from turning on your Food Processor to it running.
Turning off the Generator is done Automatically when you switch off the appliance, and the Ring Main reverts back to 12v.
The best place to find out about this equipment would be a large Marine Chandlery, as this equipment is widely used in medium/luxury Yacht's.
What happens to the 12v gear when the 240v kicks in
