Since its beginnings five years ago in Sulphur Springs, Texas, EG4 has grown to place among the largest suppliers of residential energy storage in the United States, achieving close to 1 GWh in sales over the past year. The company has around 500 employees at its base just outside Dallas working on development, manufacturing, distribution and more.
As of March 2025, EG4 assembles power inverters at the site, and has plans to further scale its US production footprint. Key to these plans is a new partnership with LG Energy Solution (LGES), comprising a six-year, multibillion-dollar contract for the supply of 13.275 GWh of lithium-iron phosphate battery cells, manufactured in the United States at LGES facility in Holland, Michigan. “Our partnership with LG Energy Solution is more than a supply agreement — it’s a commitment to possibility,” said James Showalter, CEO of EG4 Electronics. “Together, we are creating a future of renewable, reliable, and affordable energy that puts customers and communities first.”
