Quick update. We did have the 10K generator installed. The change over box (panel) is wired in between the meter and the breaker box. When the grid power goes off the system waits one minute and starts the generator. After about another minute the panel switches the whole house over to the generator. About a minute after the grid comes on, the panel switches back to the grid and shuts off the generator. That switchover back to the grid is seamless. Even the microwave doesn't lose time. This is all automatic and requires no switching from the homeowner. I picked the 10K because it came with the starting battery, a float charger, full house change over panel, and other innovations not on the smaller units and the price difference was small. It has already run at least once since we have been in Florida.
