Designers and developers of commercial and industrial buildings now have longer-lasting backup power solutions available from N1 Critical Technologies that are suitable for the whole building or select mission critical equipment.

N1 Critical Technologies sales engineers specialize in designing, installing and maintaining uninterruptible power supply (UPS) systems using the latest, powerful, long-lasting lithium-ion batteries from several manufacturers.

The company’s technical advisors have access to the very best UPS makes and models available (from Eaton, GE and others) and come with more than 40 years of combined experience in developing industrial UPS systems, commercial UPS systems, UPS systems for server rooms, and whole-building UPS systems.

In addition to designing and installing large-scale, three-phase lithium-ion UPS systems, N1C was the first U.S. company to manufacture and offer a full line of single-phase lithium-based UPS systems for smaller applications, such as server racks, network closets and point-of-sale systems.

Whether needs are high power for a building-wide application, or low power for several pieces of critical equipment, the lithium-ion batteries used in N1C-branded and other designed systems have tremendous benefits.

They offer more energy capacity in a significantly smaller space, are lighter and come with a smaller carbon footprint than traditional lead acid UPS systems. Perhaps most importantly, lithium-ion batteries have both a longer shelf life and a longer backup runtime, which lowers overall cost of ownership for the UPS and powers and protects connected equipment for longer durations during power outages.

“As a team, we have an intimate knowledge of the specifications, capabilities, and service histories of the entire range of lithium-ion UPS products and systems available in the market,” said company co-founder and CEO Nate Ellsworth. “We leverage our practical experience and expertise when designing high-quality power backup systems to give customers the longest lasting, most affordable option available that will save them money, time and hassle over the long run.

“You will find our own single-phase UPS systems and large-scale lithium-ion UPS systems we designed in facilities of all types and sizes. People are starting to realize the many benefits of lithium-ion battery technology and we’re at the forefront of the shift in the marketplace toward the technology. N1C is truly disrupting the uninterruptible power supply industry.”

Clientele for N1 Critical has included data centers, financial institutions, medical clinics, hospitals, office complexes, call centers, telecom centers, universities, school systems, television and radio stations, marine shipboard applications and many others.

“As experts, we help you in bridging the gap between the articulated needs of your IT professionals and the economic constraints of efficiently running your business,” Ellsworth said. “We do this by advising you on how you can meet and even exceed the technical requirements that IT professionals desire and we do it most cost-effectively. Lithium-ion may cost a little more up front, but when you see the savings in money, maintenance and power saving over time, it becomes a no-brainer to make the switch to lithium-ion UPS systems.”

In the ideal conditions, the average life span of a lead acid UPS battery is 4-6 years. In comparison, the lifespan of lithium-ion battery is 10-15 years, and they can withstand even harsher operating environments without performance degradation.

That means less cooling requirements and fewer batter replacements over the life of the unit, reducing the burden of downtime and maintenance.

Lithium-ion batteries can also handle more than 1,000 discharges and recharges, more than triple what a lead acid battery can handle. A lighter and smaller battery also makes installation easier and versatile. Some customers may even regain valuable space in their server room or data closet with significantly smaller lithium-ion battery cabinets.

No matter your power needs, N1 Critical Technologies can design a lithium-ion Uninterruptible Power Supply solution for you!

Matt Winter and his mom Rene.

N1 Critical Technologies will host its new headquarters grand opening and ribbon cutting ceremony from 4-8 p.m., Thursday, July 19. But it won’t be any ordinary ribbon cutting. We’re also hosting a Casino Night Fundraiser for an amazing cause. Here’s the story of why we’re doing what we’re doing…


Homebound or hospitalized kids will keep connected by using remote control robots in their schools

Matt Winter was just 13 when he lost his battle with Ewing’s sarcoma, a very rare type of cancerous tumor that grows in bones and surrounding soft tissues.

Diagnosed in May 2014, Matt won the first round of 22 chemotherapy treatments, but had his entire Tibia removed. That’s where the cancer had started.

He was a year into remission when the cancer had come back. It was May 2017, the end of his 7th grade year. Doctors gave him two weeks. He fought hard, and battled the spreading cancer until he passed Nov. 12, 2017.

Matt never got the chance to make it into the 8th grade at JC McKenna Middle School in Evansville. He was bedridden. In a hospital. Far from friends. Isolated. Feeling alone.

“He lost touch with a lot of kids, a lot of his friends, when he was sick,” said his mom Rene Wieloch.

Telepresence Robot

After Matt passed, Max Ellsworth, one of his best friends — one he never lost touch with — had an idea. Max’s dad Nate, the CEO of N1 Critical Technologies, had bought a web-remote-controlled Telepresence robot to drive around the office and have fun “peeking” in on his co-workers down the hall.

Max said that if his buddy Matt had one of the mobile robots, he could have still experienced school, at least by seeing and conversing with his friends, classmates and teachers via two-way video conferencing on the robot’s attached iPad.

“Matt was really into technology,” Rene said. “He would have loved that.”

Nate quickly realized Max was onto something.

“It was a great idea, and I knew students could get much more practical use out of the robot than I ever could around the office,” Nate Ellsworth, the company’s co-founder, said. “There is so much value in allowing homebound students to be able to connect with their classmates and teachers and at least have some sense of normalcy during difficult situations.”

The robot soon found new life at Edison Middle School in Janesville, where it is intended to serve homebound students in the same way Matt would have enjoyed if he had the chance. (See story about the donation in the Janesville Gazette.)

N1C’s Casino Night Fundraiser will support the purchase of additional telepresence robots to be donated to area schools in Matt’s name.

“When he was undergoing chemo, he was really homesick. The robot would have been very beneficial to him to be at the hospital to be able to keep up with his friends and his schoolwork,” Rene said.

Donations made by grand opening attendees who are playing the casino games or buying raffle tickets outright will support schools and support kids going through the toughest of times with the hopes of making their situations and their lives a little bit better.

Proceeds will also support the newly-created Winter’s Soldier Foundation, which was set up by Matt’s mom, Rene Wieloch. The Winter’s Soldier Foundation supports the purchase of technology — movies, videogames, computers, etc. — for homebound or hospitalized students so they can have something to remain engaged and entertained while receiving treatments.

The grand opening, ribbon cutting, and fundraiser is a Forward Janesville Business After 5 event. For full event details, click here.


The crew at N1 Critical Technologies, a manufacturer and seller of Lithium-Ion uninterruptible power supply systems — has settled into its new office in downtown Janesville. The 8,000-square-foot facility, formerly a regional office for the American Red Cross, has been renovated from top to bottom, inside and out, fulfilling the dreams of co-founders Nate Ellsworth (CEO and National Sales Director) and David Farrell (Chief Financial Officer). Come see for yourself at our open house on Thursday, July 19!

Our new N1 Critical Lithium-Ion UPS systems have arrived, were installed and are working perfectly. So what do you do with the old lead-acid UPS system you’ve replaced? Find out about recycling options for your old equipment.

Eaton Power Xpert 9395 with Samsung Lithium Ion Battery CabinetsCritical systems require a powerful battery backup solution that will ensure uninterruptible power supply. Let our sales engineers design a large cabinet lithium-ion UPS system that is a long-lasting and suitable solution for all commercial sectors.

One of the greatest challenges for businesses and industries today is maintaining a constant energy supply to keep their operations up and running 24-hours a day. With operations shifting to the digital platform, more companies are dependent on running a number of computer-aided machines, which need constant electrical energy. Industrial sectors such as data centers, telecommunication companies, healthcare facilities, government agencies, and the finance sector have been the greatest seekers of alternative solutions to mainstream connections.

Modern advancements in energy storage technologies are rapidly revolutionizing the perception and adaptation of uninterruptible power supply systems as better options are introduced to the market. Unlike the past when companies had to resort to the highly unreliable lead-acid based systems as their battery backup, lithium-ion solutions in large cabinet UPS systems are reversing the norm.

Different from their predecessors, lithium-ion batteries come designed to complement any modern system without any hassles. These UPS systems are available in a number of models, with each having unique features, power capability and battery capacity for a specified application. You no longer have to resort to the one-size-fits-all option, which was more typical of lead-acid batteries.

IT and facilities professionals who are after plenty of performance and a robust system can contact N1 Critical Technologies to have large cabinet UPS solutions designed with lithium-ion batteries. They are the ultimate solution for industries that are after powerful systems, which will support all their operations without any glitches. Lithium-ion large cabinet solutions are three-phase systems, making them ideal for maintaining substantial energy requirements of vital systems.


Advantages of large cabinet lithium-ion systems

  • Lower total costs of ownership: Given the required maintenance and replacement of lead acid battery systems, you stand to save much more over time from purchasing a single large cabinet lithium-ion system.
  • Longer life expectancy: Lithium-ion batteries are designed to last about 15 years, giving such large cabinet systems longer lifespan for continuous long-term use.
  • Safety and reliability: Large cabinet lithium-ion systems are specially designed to guarantee a constant flow of energy from a connected system of batteries. Lithium-ion is also heat tolerant, and can operate without performance degradation up to 140º. That means your batteries last, even if your AC units don’t.
  • Reduced maintenance costs: Right from the installation to maintenance, large cabinet lithium-ion systems require little or no extra special technical attention. Advanced models come with an LCD touch screen displays, which provide all relevant information concerning the system.
  • Smaller spaces, lighter materials: Lithium-ion batteries provide more energy in a smaller space than lead acid batteries of the same runtime. This reduces space needs and can even save on structural strength improvements that may be needed when installing heavy lead acid systems.
  • More charge cycles: Lithium-ion batteries are outstanding have higher charge cycle counts and take shorter time to charge back to full capacity, reducing energy costs and prolonging the life of the battery system.
