The EG4 BOSSBox is a freestanding, weather-resistant cabinet designed to house EG4 Electronics' batteries and inverters for whole-home backup, off-grid power, and commercial energy storage. It is built with durable epoxy-coated steel and provides a quieter, fuel-free alternative to traditional generators.
Key features
Weather-resistant: The BOSSBox has a pending NEMA 3R rating, protecting the components from rain, falling dirt, and ice formation. Its epoxy-coated Q235 steel construction makes it corrosion-resistant and durable for outdoor use.
DIY-friendly: Its freestanding, pallet-style base allows for easier transport and simplified installation without the need for wall-mounting.
Passive cooling: The cabinet features a passive airflow design with intake and heat vents to dissipate heat without the use of active cooling fans. Providing shade or covering in hot climates is recommended.
Quiet operation: As a silent, fuel-free alternative to generators, it is suitable for residential and light commercial use where noise and fumes are a concern.
Scalable: The cabinet can be configured with multiple compatible EG4 batteries and inverters, allowing you to expand your system as your energy needs grow.
