EG4 GridBOSS 200A MID

The EG4 GridBOSS 200A MID Provides Simplified Whole-Home Backup and Energy Management

The EG4 GridBOSS 200A MID is a high-performance power gateway and micro-grid interconnect device designed for homeowners who demand reliable, streamlined energy solutions. It manages grid, generator, inverter, backup-load, and smart-load connections.

With a 200A service entrance rating, this all-in-one system consolidates up to ten components, dramatically reducing installation complexity, hardware clutter, and overall system cost. Whether you are managing a solar energy storage system, coordinating multiple inverters, or creating a fully integrated backup power setup, the GridBOSS ensures seamless coordination between utilities, inverters, generators, and critical household or worksite loads.

Unlike traditional setups requiring multiple transfer switches, breakers, and complex wiring, the EG4 GridBOSS 200A MID centralizes control, giving you faster, cleaner, and more efficient system integration. With intelligent load management and real-time monitoring, it offers complete visibility across up to eight circuits. This level of insight allows you to optimize energy distribution, reduce waste, and maintain uninterrupted power flow even during grid outages or off-grid operations.
