From a small-town Texas base, Showalter built EG4 Electronics into a fast-growing manufacturer bringing residential solar inverters and battery storage systems to middle-class homeowners at price points that make grid independence a practical—not premium—choice.
James Showalter founded EG4 Electronics in Sulphur Springs, Texas, which manufactures and distributes residential and commercial solar inverters, battery storage systems, and off-grid power equipment.
The company has grown alongside U.S. residential solar and battery storage adoption, selling through a dealer and installer network. Showalter was a 2025 EY Entrepreneur of the Year National Emerging Award finalist in Industrials and Energy.
