Selecting the right size Cummins QuietConnect™ standby generator is important. Choose too small of a generator, and you won’t be able to power all your home’s circuits. Choose too large of a generator, and it’ll be inefficient, consuming more natural gas or propane than necessary during a power outage.

How do you perform a home generator sizing? Well, you have to do some math.

Stick with me, and I’ll show you how to make the calculations. Or, if math isn’t your thing, you can bail out now and use the generator sizing calculator.

Kilowatts
Generators are sized in kilowatts, which is 1,000 watts. Watts are a measurement of the rate of energy transfer for an appliance. Add up the wattage of every appliance in your home that draws electricity, divide by 1,000 and that’s the generator sizing formula, right? Not quite.

Running Watts vs Starting Watts
Any appliance in your home that has a motor (your air conditioner, refrigerator or sump pump, for example) has two wattage ratings: running watts and starting watts. This is because the motor needs extra electricity when it first starts. After it’s running, it needs less wattage.

When you add up your watts, you need to figure in the starting watts of the motorized appliances. Generally, starting watts are three times the running watts, but you need to check the appliance’s label to be sure.

Converting Volts and Amps to Watts
Not every appliance label lists its energy transfer rate in watts. Sometimes they list the power needed as something called volt-amps (VA). This is just another name for watts. Other times, they will list the volts and amps (other measurements of electricity) separately. To determine the watts, you will have to multiply the volts times amps (V x A = W).

Room for Expansion
Before you finish your calculations, you need to add in a margin of safety. You may buy bigger appliances or new appliances in the future. You need to take this into account before you buy your standby generator. So, once you have determined the total kilowatts your home needs, add another 20 to 25% to give you the final generator load calculation.

Easier Ways to Make the Calculation
For a rough estimate, you can use the generator sizing calculator. But for the most accurate sizing, it’s best to schedule an appointment with a Cummins authorized dealer, who will come out to your home and make the calculations for you. To find the dealer nearest you, start with the Cummins home generator dealer locator.

Preparing for Power Outages
While calculating your power needs, it is also important to consider how long an outage in your area could be. If you live in coastal areas that are frequently impacted by hurricanes, expect that your generator will be used for long power outage durations. To prepare your generator for longer run times, make sure to work with your local dealer to schedule preventative maintenance visits.

Green travel is on track: Our fuel cell systems are powering the world’s first 100%-hydrogen passenger train fleet

Holiday vacation plans? Visit us in Europe where we’re powering the world’s first fleet of hydrogen trains. The Alstom Coradia iLint trains are outfitted with Cummins fuel cell systems and run on the world’s first 100%-hydrogen-powered passenger train route. The trains convert hydrogen fuel into energy and turn existing, non-electrified infrastructure into zero-emission rail lines. These trains emit only steam and condensed water while in service and operate with low noise levels that improve both operator and passenger comfort.

The hydrogen fuel cell systems used in the trains are assembled at Cummins’ Hydrogen Fuel Cell Systems Production Center in Herten, Germany. The facility was fully operational in 2022, enabling accelerated adoption of hydrogen technologies across Europe and the globe.

North America? Check. Europe? Check. We’ve expanded our New Power footprint across the globe

This year, we drove the green hydrogen economy forward across the globe by supporting new infrastructure projects and advancing government decarbonization goals.

We have broken ground on our new gigawatt PEM electrolyzer manufacturing plant in Guadalajara, Castilla-La Mancha, Spain. Construction is scheduled to be complete by the end of 2023. The 200,000 sq. ft. facility will have the capacity to produce 500MW per year, scalable to more than 1GW per year.

Our Oevel, Belgium electrolyzer manufacturing facility expanded its capacity to 1GW thanks to the Important Project of Common European Interest (IPCEI) Hy2Tech program. IPCEI will help Cummins develop a new generation of PEM electrolyzer cell stacks to power large-scale hydrogen production systems. Operation began at our new Hydrogen Fuel Cell Systems Production Center in Herten, Germany this year, which further enables the adoption of hydrogen technologies across Europe. 

We expanded our Mississauga, Ontario, Canada campus by adding a third facility dedicated to hydrogen technology. The new facility accommodates the company’s growing staff, hydrogen production capacity and new product development, putting Cummins in a better position to support the developing hydrogen market in North America.

The wait is over - our electrified powertrains made their official debut

We unveiled the Meritor 17Xe ePowertrain integrated with a Cummins battery system. The 17Xe is designed for heavy-duty trucks with the capacity to support 44 tons of gross combined weight. The assembly also features Cummins’ new lithium iron phosphate (LFP) battery pack. 

Our clean drivetrain options offer performance and packaging advantages for diverse applications across the globe.

Electrolyzers are stateside: We’re starting production in the U.S.

We announced that we'll begin producing electrolyzers in the U.S. for the first time at our Fridley, Minnesota facility. To drive the domestic green hydrogen economy forward, we'll start at 500 megawatts (MW) of manufacturing capacity annually, scalable to 1 gigawatt (GW) in the future.

recipients holding trophies

Cummins Inc. (NYSE:CMI) announced the 2022 recipients of the company’s most prestigious technical award, the Julius Perr Innovation award. Now in its 23rd year, the award recognizes employees who demonstrated excellence in innovation and technology by developing significant intellectual property for our products.

This year’s recipients are Cummins employees Richard Ancimer, Krishna Kamasamudram, Ashok Kumar, Guoqiang Li, Tim Proctor, Michael Wilson, and Aleksey Yezerets. Acknowledgement also goes to Neal Currier, Ed Hodzen, and Vivek Sujan.

ABOUT THE INNOVATIONS

The first winning patents relate to the mitigation of sulfur accumulation on a selective reduction catalyst (SCR).

Ancimer, Currier, Kamasamudram, Kumar, and Yezerets developed methodologies to not only monitor this accumulation of sulfur but regenerate the catalysts faster, and at lower temperatures, through the synchronization of engine operating conditions during regeneration. Their work is employed on Cummins products, such as Euro IV/V/VI, EPA 2010, Tier IV, and in regions high sulfur fuel, and will likely continue playing a role in meeting future emission regulations.

Wilson developed a different approach targeted for the service channel in areas with high sulfur fuel, particularly the Euro V products in South America.  A key feature of his invention involves the deactivation of cylinders, and his work has been cited numerous times by non-Cummins patents.

For second winning technology, Hodzen, Li, Proctor, and Sujan invented the SmartTorque2 (ST2) feature, which is part of the award-winning Eaton Cummins SmartAdvantageTM  Powertrain. This feature automatically senses a variety of factors, such as grade and weight, and selects the optimum torque for performance and fuel economy. The invention was first in production in 2013 and has been a standard offering of the X15 product since 2017.

ABOUT THE AWARDS

This award was created to honor Dr. Julius Perr, who retired from Cummins in 1997 as Vice President - Fuel Systems.  Dr. Perr, who passed away in 2005, joined Cummins in 1958 after fleeing Communist Hungary.  He made Columbus, Indiana (USA) home and began a 41-year career as a Cummins engineer and leader.  In his lifetime, he was named the inventor or co-inventor of 186 granted patents and remains an inspiration to many in our industry.

Smart phones, smart TVs, virtual assistants, smart thermostats, smart locks and doorbells. Our homes are now filled with smart devices. Unfortunately, most of them become useless without power to run or recharge. This is why homeowners should consider installing one smart device above all other: a home standby generator. 

As a Cummins Authorized Dealer, I install a lot of Cummins QuietConnect™ home standby generators throughout Oregon. With increasingly severe weather, rolling blackouts, and aging power grids, I can tell you without a doubt a backup generator is a worthwhile investment. 

The best part of owning one of these smart devices? You don’t have to tell it when to turn on and off. It does it automatically. 

In a nutshell, here’s the process:

When we install a Cummins home standby generator, we also install a Cummins automatic transfer switch. This transfer switch constantly monitors the electric utility power coming into the home. If it detects a break in service, it will automatically disconnect the home from the electric utility line in a split second and turn on the Cummins generator to power the home instead. The generator is fed either by a natural gas line or by a propane tank.

While the Cummins generator is powering the home, the transfer switch will continue to monitor the electric utility line. Once it detects that power has been restored, it’ll automatically disconnect the generator from the home’s electrical system and reconnect the electric utility.

You don’t have to do anything. Nada. Zilch. The generator and the transfer switch do all the work. In some cases, you may not even realize there’s a power outage until you look out the window and see all your neighbor’s houses are dark.

Just as critical as having a Cummins Authorized Dealer professionally install your backup generator and transfer switch is making sure you choose the right size generator for your home. If it’s too small, the load won’t be able to power everything in the house. If it’s too big, you’ll consume extra natural gas or propane when you use it.

The easiest way to make sure you select the right size generator is to have your dealer do it for you. But if you want to get a feel for how much generator you’re going to need, Cummins has an excellent blog post on calculating the generator wattage you need or you can use the generator size calculator at Cummins.com.

We live in a world full of smart devices. Make sure you can keep yours up and running during power outages with a Cummins QuietConnect home standby generator.
