EG4 – Energy Independence Designed and Supported in the USA

EG4 solar batteries and inverters “empower energy independence for everyone.” The founders began by selling solar panels, but their customers had problems with the batteries and inverters available at that time. They decided to fix these problems by designing alternative solutions at competitive prices.

The founders of EG4 have always wanted to provide peace of mind through energy stability. If the power grid fails, EG4 inverters and batteries continue powering home loads.

Tariffs have disrupted pricing on many EG4 solar batteries and inverters, but EG4 is ready for the challenge. Even before the tariffs, it began shifting product manufacturing to its Dallas, TX location. By the end of 2025, EG4 plans to have all inverters meet the standards for “Made in the USA.” EG4 already produces all FlexBOSS and 12000XP inverters in the USA and will continue scaling this production to include batteries.

EG4 products support many combinations and sizes of on-grid and off-grid living. The product line includes detailed instructions so customers can confidently maintain their systems regardless of energy disruptions to the main power grid.

From the popular 18kPV and 6000XP inverters to WallMount LiFePO4 (Lithium Iron Phosphate) batteries, EG4 offers comprehensive solutions for residential and commercial applications. The Chargeverter lineup provides flexible charging options, while server rack batteries like the LL-S series deliver scalable energy storage. Each product is backed by USA-based technical support and comprehensive warranties.
