MSRP and normal operating sound from each model's page (all four carry the 7 year warranty) on Briggs and Stratton Energy Solutions, checked October 2026. Generator only.
What the List Price Does Not Include
The MSRP is the generator. An installed system also needs an automatic transfer switch, a pad, the gas or propane connection, the electrical run to the switch, the permit and inspection, and commissioning. Retailers sell some Briggs models bundled with a transfer switch, so check what a quote includes before you compare it with another brand.
Installation is priced by the dealer. Get two or three written quotes from local dealers that list the switch, the fuel work and the electrical work separately. Our transfer switch page covers the switch.
The PowerProtect+ 22 kW product page rates it at 22 kW on both natural gas and liquid propane. Air-cooled generators are often rated lower on natural gas, so compare the natural gas rating when you size against another maker.
The 7 Year Warranty
Each PowerProtect+ product page states a 7 year warranty covering parts, labor and travel, and the PowerProtect 13 kW page describes a 7-Year Comprehensive warranty with no out-of-pocket cost for labor, parts or service. Briggs calls the PowerProtect+ cover the longest and most comprehensive standard warranty in the industry. That is the maker's claim; compare it with the written warranty statement of any other brand you are quoted.
Briggs launched its earlier Fortress line in June 2016 as a premium range with a six-year parts, labor and travel warranty. Fortress does not appear in the current home standby listing.
