For natural gas, there are essentially two types of backup generation. Both portable and standby generators, if configured, can use natural gas as a fuel source. However when looking at generators that use natural gas, the typical configuration that comes to mind is standby generators.
The main reason for this, is that while some portable generators run on natural gas, standby generators are fixed and therefore easily tied into the home natural gas service.
This is important for a couple of reasons. To start with once the generator is installed, there is little reason to deal with the natural gas connection.
Natural Gas Vs. Propane Vs Gasoline
Where natural gas excels is the fact that if it is connected to the house main it offers an almost unlimited run time. It is true that gasoline comparatively produces more power per unit. Meaning that one gallon of gas is the equivalent of 1.36 gallons of natural gas. The same with propane, however the run time is longer due to a commercial connection, i.e. the home versus a portable tank like gas or propane.
It is further true, that some portable generators can connect via a quick connect/release mechanism to the house gas line, it represents a potential failure point during use and therefore is more dangerous compared with the standby generator connection. So, essentially that is why these are all standby generators being reviewed instead of the portable ones.
Number 5: Generac 5818 EcoGen Series 6000 Watt Standby Generator
Generac is a leading brand in power generation. Producing generators of all sizes and shapes from small portable generators to large commercial and industrial gen sets. The Generac 5818 EcoGen series pumps out a nice 6000 watts of full capacity.
What makes this natural gas powered generator a good purchase, is the extremely long run time between oil changes. The premium oil recovery system means that the unit can run for 500 hours before needing to change the oil.
This makes it perfect for off grid or the secondary lodge. With that in mind, it is specifically engineered to run with renewable energy sources to provide standby power when the wind is not blowing or on a cloudy day.
Number 4: Generac 6237 8000 Watt Standby Generator
This natural gas powered generator produces 8000 watts of power. Enough to keep a small or medium home running. The Generac 6237 8000 Watt Standby Generator activates in seconds when a loss of grid power is detected and is designed to keep producing power.
It is fully CARB compliant and is engineered to be located close to the home. In fact, it is so well engineered as to be installed within 18 inches of the home.
This a lot closer than even portable generators should be located to the home. (5 feet minimum for portable generators.). It comes with a 10 circuit transfer switch and will provide an almost unlimited run time.
Number 3: Briggs & Stratton 40450 10,000 Watt Generator
Powered by natural gas, the Briggs & Stratton 40450 10,000 Watt Generator produces a very healthy 10,000 watts of capacity. More than enough to power a small or medium home, including the central heating and air system. It comes with a 200 amp transfer switch and uses Briggs & Stratton power technology to quickly activate in case of an outage.
It is also very compact for a standby generator and can be located as close as 18 inches to the home. It also has technology that helps manage the load but also the electrical draw in the home to make sure that all appliances and devices are getting the right amount of power.
This is important for sensitive electronics. This can also be vital to any home that uses medical equipment. Small in size, but big on power, this generator can produce the power with an almost unlimited run time.
Number 2: Generac 6439 11,000 Watt Standby Generator
The Generac 6439 11,000 Watt Standby Generator is designed to deliver 11,000 watts of power and run for 200 hours before needing an oil change. The amount of power this generator supplies is more than enough to handle a medium to large home and keep everything running.
Being powered by natural gas, this generator has an almost unlimited run time and has a total harmonic distortion of less than 5 percent. The True Power technology, keeps the power on track and regulated for even the most sensitive of electronics. It also is easy to install.
One of the advantages of Generac generators is the low pressure technology that allows for low pressure in the gas line that would prevent any other natural gas generator from running. This keeps the power flowing and the lights on even in adverse conditions.
Number 1: Kohler 14RESAL-200 14,000 Watt Generator
The Kohler 14RESAL-200 14,000 Watt Generator is no different. Producing more than enough power, at 14,000 watts, to power a medium to large home, this generator can handle any power demand.
Central heating and air units, sump pumps, freezers etc are all able to be powered by this generator. One of the advantages of this unit, is that it is specifically engineered to withstand even the most adverse of conditions including those found on the sea shore.
The enclosure can handle up to 150 mph winds and still supply power. For anyone who wants dependable power to handle a wide variety of power demands, the 14RESAL-200 can handle it and the environment at the same time.
All these generators are great for home use. There is always a change that a home will experience conditions that can cause an extended outage and these generators make sure the home and surrounding can be power in such a case.
