Briggs & Stratton PowerProtect™ DX 13kW Home Standby Generator
Big protection, small footprint. The PowerProtect™ DX 13kW (model 040740) delivers dependable automatic backup power in an enclosure that’s 39% smaller than competitive models — perfect for tight side yards, zero-lot-line homes, and properties with strict setback rules. Its upright design with front-facing exhaust is approved for installation as close as 18 inches from your home.

Who Is the 13kW Right For?
The DX 13kW is our most affordable whole-home entry point. It comfortably backs up the essentials — furnace, refrigerator, sump pump, well pump, lights, internet, and select circuits — for most small to mid-size homes. Pair it with Symphony® Choice Power Management and it can manage larger loads intelligently, letting a smaller generator do a bigger job for less money.
