What moves your number
- Unit price. Our catalog's 2 models at10 kW range from$3,649 to$4,619 (MSRP). Sales and bundling move this.
- Transfer switch. A bundled ATS (included with some SKUs) cuts the switch line item; an oversized or whole-house ATS adds to it.
- Site work. Long gas-line runs, a subpanel, or an electrical upgrade push labor toward the high end.
- Region. Labor rates vary; our estimator lets you set a low/avg/high cost area.
