EG4 Electronics' batteries and inverters “empower energy independence for everyone.” As EG4 has developed, it has engineered solutions for solar customers’ major pain points. While the founders began by selling solar panels, they have switched primarily to designing and manufacturing batteries and inverters at competitive prices, always with the goal of providing peace of mind through energy stability.
Tariffs have destabilized pricing on a variety of products, but EG4 is ready for the challenge. Over the course of 2025, EG4 made great strides to qualify their inverters for "Made in the USA." EG4 already produces several inverters in the US and will continue scaling their US production to include batteries.
EG4’s products support a wide variety of applications for combinations of on-grid and off-grid living. These products include detailed documentation so customers can confidently maintain their systems regardless of energy disruptions to the main power grid.
