Stand by generator, depending on where you live, to buy it and have it installed will be somewhere in the ballpark of $10,000. For a manual system the costs will be the portable generator the transfer switch (gen interlock if permissible in your area), the wire to the inlet box and the cost of the electrician. So, $1100-$2600 for a good quality generator plus $100-600 for the transfer switch, $200 for cabling and an inlet box, and ~$1000 for electrician. Possibly $2500-$4000 to do it right on a manual system. For my house, it is a manual system, for my parents, I installed a Generac with ATS. Peace of mind makes the difference.
