EG4 Electronics GridBOSS MID V2 200A Service Entrance

EG4® GridBOSS – The Ultimate Microgrid Interconnect Solution

The EG4 GridBOSS redefines what a Microgrid Interconnect Device (MID) can do, offering unmatched versatility, intelligent design, and advanced energy flow management. Engineered to outperform any other MID or power gateway in its class, the EG4 GridBOSS simplifies solar and hybrid energy system configurations, significantly reducing both installation time and hardware costs.

With four smart, programmable ports capable of AC coupling or load management—up to 125 Amps—this device serves as a centralized hub for hybrid inverters, generators, utility power, and critical load circuits. Its powerful 200A service entrance rating consolidates multiple electrical components into one smart, scalable system.

Whether you’re managing whole-home backup, partial load systems, or building a microgrid, the EG4 GridBOSS provides the flexibility and power you need. When paired with the FlexBOSS21, it streamlines system design, cuts costs, and ensures seamless energy flow in all operating conditions.
