13kW Briggs & Stratton PowerProtect Standby Generator - 120/240V, Dual Fuel (LP/NG), NGMax, 6-Year Warranty - Model 040746

Briggs & Stratton 13kW PowerProtect Standby Generator – Whole-Home Backup Power with NGMax Technology The Briggs & Stratton 13kW PowerProtect Standby Generator (Model 040746) delivers automatic whole-home backup power for families who refuse to let a storm or grid failure disrupt their lives. When utility power fails, this generator detects the outage and restores power to your home automatically — keeping your air conditioner, furnace, refrigerator, lights, computers, and kitchen appliances running while your neighbors wait in the dark. Engineered with Briggs & Stratton's proprietary NGMax technology, the 040746 delivers more power on natural gas than competing units in its class — producing 13kW on LP and 11kW on natural gas. It connects to your existing home gas line for continuous, uninterrupted fuel supply with no tanks to fill, no fuel to store, and no trips to the gas station during a storm. Liquid propane is also fully supported for homes without natural gas service. Vanguard® Commercial-Grade Engine At the heart of the 040746 is a Vanguard V-2 commercial-grade OHV engine with an aluminum cylinder block and cast iron sleeve, running at up to 3,600 RPM. Designed by Briggs & Stratton's engine experts for reliable, continuous performance, this engine is built to a commercial standard — not a consumer standard — giving homeowners the durability and longevity normally reserved for commercial applications. Schaeffer 5W30 Full Synthetic Generator Oil is recommended for reduced engine wear and cold-weather starts as low as -20°F. 39% Smaller Footprint — Installs Where Others Can't The PowerProtect 040746 features a 39% smaller footprint than other leading generators of similar output, with an upright design that minimizes the installation area required. Its front-facing exhaust design allows installation as close as 18 inches from your home — making it the right choice for properties with tight lot lines, side yards, or limited outdoor space where standard generators simply won't fit. Eco-Cise™ Weekly Test Mode The 040746's 16-second weekly test mode automatically exercises the generator to verify it's ready for the next outage — while minimizing noise and fuel consumption compared to the longer exercise cycles on competing units.

The removable roof and front panel provide easy access to the engine and alternator for routine maintenance and service — no special tools required. InfoHub™ Remote Monitoring & Symphony® Power Management The optional InfoHub wireless monitoring system lets you check generator status, receive service alerts, and monitor your unit from anywhere using an iPhone, iPad, Android device, PC, or Mac — so you always know your home is protected even when you're away. The optional Symphony® Choice Power Management system lets you prioritize which circuits receive power during an outage, allowing a smaller generator to efficiently manage a larger home's electrical loads without overloading the system. 37 kVA Motor Starting Power With 37 kVA of motor starting capacity, the 040746 handles the high startup loads of central air conditioners, well pumps, sump pumps, and other motor-driven appliances that require significantly more power to start than to run — preventing nuisance shutdowns during the critical first seconds of an outage. Model: 040746 Warranty: 6-Year Parts, Labor & Travel | 1-Year Enclosure Surface Rust & Corrosion | 2-Year Enclosure Rust-Through FAQ What will the Briggs & Stratton 13kW 040746 power in my home? The 040746 is sized to power essential whole-home circuits including your central air conditioner, furnace or heat pump, refrigerator, freezer, lights, fans, computers, televisions, and kitchen appliances simultaneously. For larger homes or those wanting to power everything at once, the optional Symphony® Choice Power Management system allows you to prioritize loads and maximize coverage from the 13kW output. What is the difference between 13kW on LP and 11kW on natural gas? Natural gas has a lower energy density than liquid propane, which reduces output slightly on NG vs. LP. The 040746's NGMax technology is engineered to minimize this gap — delivering 11kW on natural gas compared to competitors that may produce only 9kW–10kW on the same fuel. If maximum output is critical, LP is the higher-output fuel option. If convenience and continuous fuel supply are the priority, natural gas is the better choice for most homeowners. How close to my house can the 040746 be installed? The PowerProtect 040746's front-facing exhaust design allows installation as close as 18 inches from your home — significantly closer than most competing generators. This makes it ideal for properties with tight side yards, small lots, or limited outdoor space. Always follow local codes and the installation manual requirements, including carbon monoxide detector installation. Does the 040746 turn on automatically during a power outage? Yes. When paired with a compatible automatic transfer switch (ATS), the 040746 detects a utility power failure and starts automatically within seconds — restoring power to your home without any manual intervention. An ATS is required for automatic operation and is sold separately. What is included in the 6-year warranty? The Briggs & Stratton 6-year limited warranty covers parts, labor, and travel — with no out-of-pocket costs for covered repairs, a value of up to $735 according to Briggs & Stratton. This is the most comprehensive warranty in the residential standby generator category. Enclosure surface rust and corrosion are covered for 1 year; rust-through is covered for 2 years.
