The EG4 GridBOSS MID is a revolutionary power gateway designed to simplify and optimize modern energy storage systems. By consolidating up to ten components into a single, centralized unit, the GridBOSS offers unrivaled capabilities, reducing the complexity and cost of system installations while providing seamless control of utilities, inverters, generators, and loads. Engineered to outperform traditional Micro-Grid Interconnect Devices (MIDs), the GridBOSS provides a 200A service entrance rating, cutting-edge smart load management, and flexible port configurations, making it the perfect solution for whole-home backup power, micro-grid setups, solar ESS, commercial systems, and a wide range of energy optimization applications.
The GridBOSS MID all about simple, effective integration, combining your utility power connection, up to three 90A inverters, and four programmable smart ports capable of AC coupling and managing high-demand loads, all into a single device, eliminating the need for additional breakers, transfer switches, or complex wiring setups. Plus, when it comes to your power, visibility is essential and the GridBOSS was designed with that in mind, featuring real-time remote monitoring and management capabilities through EG4’s updated monitoring software, which tracks energy flow across eight different circuits for optimal system performance. The GridBOSS not only organizes your system while enhancing efficiency, but this state-of-the-art hub simplifies the installation process, reducing hardware and labor requirements, and saving you thousands in install costs.
