Engine
Briggs & Stratton powers the 40346 with its own popular and reliable Vanguard 993 cc V-Twin overhead valve engine. The electronic engine governor incorporated into the generator design keeps the Vanguard operating at a constant 3600 RPM, even under heavy and changing loads, to keep the AC signal constant at 60 hertz. The air cooled engine has a fully pressured lubrication system and oil cooler, with a low oil pressure sensor that allows engine shut down to prevent damage.
Fuel
The 20kW standby unit is factory configured to run on natural gas, but converts easily to liquid petroleum gas (propane) during installation by simply turning a selector screw with an Allen wrench. Operating on LP gas provides up to 20 kW of power. At half-load, the engine consumes about 2.3 gallons of LP fuel per hour. Natural gas supplies up to 18 kW of power, and consumption runs about 83 cubic feet per hour at half load. Fuel consumption varies along with the electrical load and is affected by altitude and ambient temperature.
Backup Power
Standby generators are permanently installed appliances that operate automatically without intervention. A power outage is sensed immediately and after a short delay to prevent unnecessary starts during momentary outages, the engine is started and brought up to speed. The automatic transfer switch disconnects the home from the utility supply lines and connects it to the generator, effectively isolating the home from the electric utility.
The generator's controller continuously regulates the voltage and frequency to provide power that meets or exceeds electric-utility standards and is suitable for sensitive electronics in addition to lighting and appliance loads, including air conditioners.
Transfer Switch
The included 200-amp automatic transfer switch (model 71068) is a service entrance rated switch that includes the service disconnect. It installs indoors or outdoors and is typically placed between the electric utility meter and the main service panel. In this configuration, the switch controls the source of power to the main circuit breaker panel by selecting between utility power or generator power, which eliminates the need for additional subpanels and allows the generator to supply power throughout the home.
The Symphony II Power Management automatically balances the power needs of your home's electrical loads - including high wattage items like air conditioning units, electric stoves and electric dryers. Requires the purchase of Symphony II Remote Modules.
Warranty
Backed by a 5 Year Parts, Labor and Travel warranty. Briggs and Stratton will be delivering the most comprehensive warranty that supports their commitment to quality, durability, reliability.
Options - 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.
Maintenance kits include everything necessary to keep your generator running and supplying power, even through extended outages with oil and air filters, filler funnel, and spark plugs. Cold weather kits add two oil warmers and a battery warmer for easier and more reliable starts in cold weather down to -25 Fahrenheit.
Add a wireless monitor and keep track of your generator from indoors and eliminate trips outside during inclement weather.
Appearance
The exterior cabinet is made from rust resistant Galvanneal steel and painted in a process similar to that used by the automotive industry for years of corrosion- free use. It rests on a prepared gravel bed or concrete pad, is 47 inches wide and 29 inches deep. At just 69db, the generator produces noise similar to a central air conditioning unit.
*You must verify the actual starting amp requirement for your air conditioner(s).
