Tesla...that is a great idea.
In the above simple layout...generator #1 is for the most important loads and #2 and #3 are for areas of the property that don't need power all the time. This approach allows for shut down of generator #2 and #3 when not needed, thereby saving alot of fuel.
The idea behind the pin & sleeve is to allow connection to an alternate generator if another were to fail in the group of 3.
As for cost...lets say all equipment cost about $18K-$20K...this isn't that much more than one large generator and would save alot of fuel.
Thanks for the input.
