Comparison of Briggs and Stratton Standby Generators from 8 KW to 20KW

Though these generators come in different sizes they have some common features like:

  • All of them can run on either Liquid Propane or Natural gas though their performance varies depending on the fuel.
  • These standby generators are operated with the use of a transfer switch which detects the utility power supply and automatically turns the generator On when there is a failure in the power supply and turns the generator Off when the utility power supply is restored.
  • All the standby generators provide 120/240 Volts of single phase AC current and they are all equipped with voltage regulators to ensure that you get a steady supply of power without any voltage fluctuation.
  • These standby generators are equipped with full pressure lubrication for their engines to ensure a long and reliable life.
  • All Briggs and Stratton standby generators are equipped with an automatic weekly exercise system which ensures that they are ready to supply you with electrical power whenever you have a power outage.
  • These standby generators are housed in Galvanneal steel which provides superior corrosion resistant that protects the generator from the elements.
  • They all come with hour meters which lets you know when they need maintenance.
  • These standby generators are equipped with over crank protection which protects the engine.
  • These generators are covered by a Briggs and Stratton 4 year limited warranty that covers both parts as well as labor.

20 kW Standby Generator Systems have dimensions of 48 x 34 x 31 inches ( L x W x H ) and they weigh in at 500 lbs.

All of these generators are stationary generators and need to be installed in a permanent location. Due to the weight of these generators you need mechanical help of a machine or forklift to place them on their permanent location. The 8 kW generators though can be manually lifted and placed on their permanent location though this needs to be done carefully so as not to damage the generator.

Typical uses and needs

The Briggs and Stratton Standby generator system generators are stationary generators and are meant to be placed in a permanent location. These standby generators have automatic transfer switches that detect the supply of power from the utility company and turn the generator On automatically when they detect a power outage and shut the generator when the power is restored.

These standby generators are ideal for use as a backup power source for your home in case of power outages. The 8kW generators can run the essentials in your home while the 10KW, 12kW, 16kW and 20kW generators are capable of running your whole home.

These generators can also be used by small businesses as a back up power source in case of emergencies to keep their business running during power outages.

These are strong engine systems and can be run close to 75% capacity with good success. Generally it is suggested you take the time to figure up your load needs and adjust for fuel type and elevation and size the generator to 1.5 to 2 times that need. This is only a rule of thumb but useful for quick sizing purposes.

Pros and Cons

The Briggs and Stratton 12kW, 16kW and 20kW Standby Generator System generators have their control panel located inside the generator housing. When you look at the control panel you will find that to the left of the control panel you have a circuit breaker that protects the system from over current situations.

On the control panel to the left you have the 15 amp fuse which protects the generators DC control circuits. To the right of this switch you have the System switch which has 2 positions. The Auto position lets the generator start and shut down automatically as it detects the power outage as well as the restored power.

The Off position turns off the running generator and resets any detected faults. Next to this switch to the right you have the Manual Override button which is used to manually start and stop the generator. Below this button you have the Set Exercise button which is used to set the exercise cycle of the generator. To the right of these buttons you have a digital display that displays the hours the generator has been running as well as the fault codes.
