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 noticed that inverters and batteries were a major customer pain point. Since then, EG4 has mostly switched to designing and manufacturing batteries and inverters. These products are sold at competitive prices, providing peace of mind even if the grid goes out.

Tariffs have disrupted pricing on many products, 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 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.
