Sol-Ark & Renon Power: C&I Focus

4:00 PM

Upstart Power: NXG Fuel Cell

The NXG is a next-generation solid oxide fuel cell that runs on propane or natural gas, pairs seamlessly with solar and battery storage, and delivers whole-home energy independence with virtually silent operation. Come see why this technology is changing the backup power conversation.

Keynote Speakers

James Showalter — Founder, EG4 Electronics

James Showalter’s solar journey started during Hurricane Ike in 2008, when a teenage James and his brother John sat without power and started crunching numbers on solar technology. That curiosity led to building their first whole-house system, launching an installation business, and eventually founding EG4 Electronics — now one of the most recognized names in the industry. Built on the belief that solar should be affordable and installer-friendly, EG4 has grown from a battery startup into a full lineup of inverters, batteries, and complete energy storage systems. James will share the story behind EG4, the thinking behind their products, and where he sees the industry heading next.

Luke Kuepfer — Speaker, Author & Business Coach

Luke Kuepfer is a speaker, author, and business coach who has spent more than 20 years helping leaders build stronger teams and healthier company cultures. He specializes in the people side of running a business — employee engagement, serving leadership, and customer service — and his workshops are known for being practical and immediately applicable. At this year’s conference, Luke will lead the Owner’s Breakfast discussion on building a positive and productive work environment and follow up mid-morning with his Winning at Customer Service session built around a simple framework: Serve. Support. Succeed.

About the Organizers

Zonna Energy was founded in 2008 by Jonathan Miller to supply off-grid solar equipment to the growing network of installers across the U.S. Over the next decade, the business grew significantly, shipping to installers across north America. In 2018 the company was sold to a new ownership group. Over the next few years, many major brands were added to our portfolio of quality products. Today, we remain committed to partnering with the best off-grid manufacturers in the world. If we sell it, we stock it. Our price will be right, but our technical support is even better. When you are looking for a company to purchase battery-based solar equipment, think of Zonna Energy.
