Home battery storage sits at less than 1% market penetration in America. The solar industry spent years focused on small urban systems while whole-home backup solutions remained out of reach for most homeowners.
Tim Montague sits down with James Showalter, founder and CEO of EG4 Electronics, to discuss whole-home backup solutions that provide true energy independence. James shares his journey from installing off-grid systems at age 15 to building one of America's fastest-growing solar and battery companies.
EG4 Electronics is a premier solar manufacturer based in Texas, dedicated to delivering high-quality, affordable, and reliable energy solutions. Specializing in advanced LiFePO4 batteries, hybrid and off-grid inverters, and fully integrated energy storage systems (ESS), EG4 is committed to empowering homes and businesses with energy independence.
KEY DISCUSSION POINTS:
Battery storage adoption remains below 1% of American homes, with James predicting a majority will have batteries in his lifetime, as costs decline and whole-home solutions become viable across broader geographic markets
Industry concentration on small urban residential systems left whole home backup opportunities underserved in suburban and rural markets
EG4's product strategy offers installers choice between different battery configurations, letting them select the right solution for each customer's needs and budget constraints
Virtual power plant programs create revenue opportunities for homeowners participating in grid services while maintaining control over backup reserves and weather-based charging schedules during potential outage periods
Texas manufacturing facility started hybrid inverter production in March 2025, with battery assembly expansion planned for 2026 using partnerships that provide component supply options for both domestic content and cost-focused projects
Whole home backup requires different economics than partial backup systems popular in dense urban areas, driving EG4's focus on affordability and power capacity for homes with higher energy loads
Partnership approach with LG Energy Solutions provides one path for installers needing domestic content compliance, while maintaining imported options for projects where upfront cost determines feasibility
The residential battery market hasn't scratched the surface. Current adoption sits below 1%. The solar industry concentrated on one narrow segment while whole-home storage opportunities in broader markets went largely unaddressed. EG4's approach focuses on those overlooked opportunities. They target independence-minded homeowners who want affordable energy resilience.
