Cummins RS20ACE 20kW Quiet Connect Standby Generator with ATS | Reliable Whole-Home Backup Power

In today’s fast-paced world, electricity powers our lives in ways that are often taken for granted. From lighting our homes to running critical medical devices, the electricity grid keeps us connected, comfortable, and safe. But when the power goes out, the consequences can be devastating. Natural disasters, power grid failures, and even the occasional technical malfunction can disrupt our daily lives for hours or days.

For those who cannot afford extended blackouts or interruptions in service, the Cummins RS20ACE 20kW Quiet Connect Standby Generator is the solution. This air-cooled, 20kW standby generator combines efficiency, quiet operation, and ease of use to provide reliable power when it’s needed most. Whether you’re looking to power your home during an emergency or ensure your business keeps running smoothly during an outage, the Cummins RS20ACE delivers performance you can trust.

Why Do You Need a Standby Generator?

 

As natural disasters become more frequent and power grids become more vulnerable, it’s crucial to have a backup power solution that can keep your lights on and your systems running without disruption. Standby generators like the Cummins RS20ACE are designed to do just that. Unlike portable generators, which need to be manually started and connected, standby generators are permanently installed and automatically activate when the grid goes down, providing seamless power to your home or business.

The RS20ACE provides 20kW of power, which is enough to run essential household appliances, including:

 

• Heating and cooling systems (HVAC)
• Refrigerators and freezers
• Medical equipment
• Lights and outlets
• Home offices
• Small businesses

 

In addition, the RS20ACE is air-cooled, meaning it requires less maintenance than liquid-cooled systems and is designed for long-term, efficient operation.

Understanding the Cummins RS20ACE Generator

Power Capacity – 20kW for Whole-Home Use

The Cummins RS20ACE is a 20kW generator, which means it can supply up to 20,000 watts of power to your home or business. This is more than enough for:

• Essential loads, such as lighting, refrigeration, and basic electronics
• Air conditioning systems in moderate-sized homes
• Water pumps and well systems
• Critical medical equipment for vulnerable family members or residents

The 20kW rating of the RS20ACE ensures that even larger homes with multiple air conditioners, high-efficiency appliances, and home offices can continue functioning as normal during power interruptions. By choosing the right generator size, homeowners can avoid the frustration of overloading their system during an outage.

Quiet Connect™ Technology

One of the standout features of the RS20ACE is its Quiet Connect™ technology. Noise is a common issue for homeowners considering a standby generator, but Cummins has engineered the RS20ACE to operate quieter than most comparable models. This is especially important in residential areas where noise restrictions are in place.

The Quiet Connect™ design utilizes special materials and sound-dampening techniques that significantly reduce noise levels. In fact, the RS20ACE runs quieter than many air-cooled units in its class, making it one of the most residential-friendly options available.

With the RS20ACE, you don’t have to worry about the generator disturbing your neighbors or compromising the tranquility of your home. It’s ideal for homes with tight space requirements or where noise control is paramount.

Key Features of the Cummins RS20ACE

1. Air-Cooled Design for Low Maintenance

The RS20ACE utilizes an air-cooled engine, which is more efficient and requires less maintenance than liquid-cooled systems. Unlike traditional engines that rely on water for cooling, air-cooled engines use the ambient air to maintain optimal operating temperatures.

• Fewer moving parts and simpler design means less chance of wear and tear over time.
• Longer intervals between maintenance compared to liquid-cooled units.
• Lower operating costs and maintenance fees.

 

The air-cooled design makes the RS20ACE an excellent choice for homeowners seeking a low-maintenance, cost-effective generator option without sacrificing performance.

2. Integrated 200A Service Entrance Rated (SE) Automatic Transfer Switch (ATS)

A standout feature of the RS20ACE is its integrated 200A Service Entrance Rated (SE) Automatic Transfer Switch (ATS). The ATS ensures that when the grid power goes down, the RS20ACE automatically takes over within seconds. The switch safely disconnects your home from the utility grid and connects it to the generator, ensuring uninterrupted power.

 

• Seamless transition between grid and generator power
• Automatically restores power to your home when utility service resumes
• Prevents backfeeding, which can damage equipment and endanger utility workers

 

This feature makes the RS20ACE a set-it-and-forget-it system, ensuring that you never have to worry about manually switching power sources during an outage.

3. Flexible Fuel Options: Natural Gas or Propane

The Cummins RS20ACE can operate on either natural gas or propane, making it adaptable to different environments. This flexibility allows you to choose the best fuel option based on availability, cost, and convenience.

• Natural gas is often the most cost-effective and readily available fuel for residential backup generators.
• Propane is ideal in areas where natural gas lines are unavailable, providing a viable backup option.

Having both options available means that the RS20ACE can be tailored to fit your unique energy needs, ensuring flexibility and dependability in any situation.
