A standby generator is in place to pick up the power demand when a grid outage occurs, thereby providing backup power automatically when needed.
You will find that the cost to install an average standby generator depends upon the power and class ratings, power transfer controls, job preparation and special requirements, and the labor rate.
In the following table the Labor Cost figure is what the able and prepared DIY persons should expect to save by performing the corresponding tasks.
Install backup generator: to automatically provide backup power with engine start and circuit transfer on grid outage; hard wired interface at home load center.
|Item||Unit Cost||Quantity||Line Cost|
|Engine generator set: outdoor pad-mounted, air-cooled with 7000 watts output; LP or natural gas fuel; rain-tight enclosure; 10 second backup response time; unit delivered and placed.||$2,530||each||1||$2,530|
|Upgrade: additional cost to upgrade to a 100 amp, 16000 watt, engine generator set.||$1,610||each||1||$1,610|
|+ Labor Cost (electrical)||$42||per hour||3||$126|
