EG4 GridBOSS

• Simple Install
• 4-Smart Ports
• EG4 Connect

Every other MID; made simple.

The EG4 GridBOSS beats every Microgrid Interconnect Device (MID) / power gateway on the market in terms of capabilities and ratings. The GridBOSS simplifies the design and operation of complex solar installations, reducing hardware costs and installation time. Featuring four intelligent ports for AC coupling or smart load management up to 125 Amps, it consolidates multiple electrical components into a single device with a 200A service entrance rating.

The GridBOSS serves as a centralized connection point for utility power, up to three 90A hybrid inverters, four programmable smart/AC-couple ports, and a generator (up to 125 Amps). It is rated for 200 Amps for both backed-up and non-backed-up loads, ensuring seamless operation under high load conditions and continuous power to essential loads during grid outages.

When paired with the FlexBOSS21, the GridBOSS significantly reduces installation expenses by eliminating extra components and installation time, making it an efficient, cost-effective solution for whole or partial home backup and microgrid setups.
