Product Description

The 10kW standby home generator system provides your family with peace of mind during a power outage with a smaller, sleeker generator,  The 10kW system is designed for homes up to 5,000 square feet.  With Patended Symphony II Power Management technology, the 10kW generator system powers more of your home's appliances - including up to two 3-ton air conditioning units*. Requires the purchase of Symphony II Remote Modules.  Up to 8 modules can be added to ensure the generator won't overload.

Placement & Safety

Briggs & Stratton designed the new 10kW generators with a front-facing exhaust and for full compliance with NFPA 37 (National Fire Protection Association regulations for placement of internal combustion engines) which allows more placement options than other generators in the same power class. An automatic, thermally-activated fuel shutoff valve and all steel cabinet make these standby generators safe for installations as close as 18 inches to the home. They fit well in small yards and where tight lot lines make placement difficult for other generators.


Briggs & Stratton uses a Vanguard 570 cc OHV commercial duty engine in its 10-kilowatt standby generators for long-lasting, reliable performance and durability. Improved easy access to the engine and alternator ease routine maintenance when it's time to add oil or change filters and spark plugs. The time-tested Vanguard engine ensures your generator will start when the power goes out and keep keep running until utility power is restored.

The engine operates on natural gas or liquefied petroleum (LP) gas. Briggs & Stratton standby generators are configured at the factory for natural gas with a fuel selector for propane.

Automatic Transfer Switch

10kW standby generators have a number of automatic transfer switch options.

Included is the service-entrance-rated switch in 150 amp model 71070 installed between the meter and the existing main panel to provide managed whole-house power and the capability to run two, 3-ton air conditioners with Symphony II Power Management.

The whole house switches supply electrical power to all circuits including freezers, refrigerators, air conditioners, water and sump pumps, lights, and television. When an outage strikes, the transfer switch powers the house with electricity from the standby generator, but prevents dangerous backfeeding of utility lines―essential for protecting utility workers and required by many utilities.


The onboard controller monitors the engine and alternator output, and maintains the correct generator frequency and voltage for clean power comparable to the electric utility and suitable for computers and other electronic devices. The safety sensors include low frequency or voltage, low oil shutdown, engine temperature and speed, transfer switch status, and battery voltage.

Appearance and Noise

With a noise level of about 75db, the 10kW standby generator compares to a five-ton central air conditioner. It has the smallest footprint in its power class at just 35 inches high, 28 inches wide and 24.4 inches deep. The Gavanneal steel cabinet―the same steel used by the automotive industry―offers a chip and rust-resistant finish that performs even in a coastal climate and keeps the generator looking good for years to come.

Optional Accessories - Sold Separately

The addition of remote power generator modules adds a managed power option which allows the generator to supply power to all your home's high-voltage, high current appliances including dryers, hot water heaters, and well pumps.  Installed directly to a home's exisitng wiring Symphony II automatically manages the distribution of power to the electrical loads, providing power where it's needed while preventing a generator overload.

Cold-weather kits tested to -20 Fahrenheit ensure the generator will operate even in cold weather. The kits include a temperature controlled battery warmer and two oil heaters to ensure cold weather starting even in harsh, winter conditions.

A basic wireless monitor eliminates trips outdoors to check on the generator. Mount it inside and know your generator is operating as it should without making a trip outside to check its operation.

Maintenance kits include oil, oil filters, air filters, and spark plugs. You won't have to hunt for parts when your standby generator needs maintenance, and you'll know you have the right supplies to complete the job. Keep spare maintenance kits on-hand to ensure you have the required supplies during a long-term power outage.
