The EG4 GridBOSS 200A MID is an advanced power gateway and micro-grid interconnect device designed to simplify and optimize modern energy storage systems. Rated for 200 A service entrance, it consolidates up to ten system components into one centralized unit, reducing installation complexity, hardware requirements, and overall system cost. Ideal for whole-home backup, solar ESS, micro-grids, and commercial power systems, the GridBOSS delivers intelligent load management and seamless coordination between utilities, inverters, generators, and connected loads.

Supporting up to three 90 A inverters and four programmable smart load ports with AC coupling capability, the GridBOSS eliminates the need for additional transfer switches or breakers. With real-time monitoring and remote management through EG4’s software—tracking energy flow across up to eight circuits—the EG4 GridBOSS MID provides unmatched system visibility, faster installs, and a cleaner, more efficient ESS integration for both on-grid and off-grid applications.
