Inlet, transfer switch, or standby: picking your rung
A portable generator with a panel inlet and interlock is the entry point: safe, code-legal, and enough to run the essentials you pick. A manual transfer switch adds a dedicated essentials panel. An automatic standby unit takes over by itself the moment the power drops. On the electrical side, the portable setups run $800 to $2,500 installed and permitted, with the portable unit itself, your purchase, typically $500 to $2,500. Standby systems run $6,000 to $15,000 or more installed. The generator cost guide lays out every factor behind those ranges.
