Used 150A Generac Guardian XFER switch to generator start.
Had this as my house switch for a year and then upgraded to whole house 200A version. I used it for a single year.
I've had this ever since just sitting in storage, indoor, and dry.
It has all the circuit breakers /w GFCI and AFCI. Local supply companies will have them if different ones are required.
New switches are $800 minimum and do not have breakers included.
Could be used as automatic failover for a solar array where the solar/battery is primary and the grid connection as backup.
