Product Description
EG4 GRIDBOSS Service Box 200 Amp Micro-Grid Interconnection Device (MID)
The EG4 GridBOSS Micro-Grid Interconnection Device (MID) simplifies Energy Storage Systems (ESS) by consolidating multiple components into a single, innovative unit. It replaces traditional elements such as the point of common connection, back-fed breakers, feeder taps, tap breakers, supply-side taps, transfer switches, and dedicated combiner panels for grid-in, grid-out, and generator input. As a versatile solution, the GridBOSS serves as the service entrance equipment* when paired with the utility meter, providing a single point of connection for utilities, hybrid inverters, generators, smart loads, and AC-coupled inverters.
- 200A SERVICE ENTRANCE
- 4 CONFIGURABLE SMART PORTS
- INTEGRATED GENERATOR SUPPORT
CENTRALIZED ESS CONTROL
- Provides a single point of connection for utility, hybrid inverters, generators, smart loads, and AC-coupled inverters.
REDUCED ESS COMPLEXITY
- Replaces up to 10 components with one unit, including point of common connection, back-fed breakers, feeder taps, feeder tap breakers, supply side taps & breakers, transfer switches, and dedicated combiner panels for gridin, load/EPS, and generator input.
SERVICE ENTRANCE RATED
- 200 Amp service entrance with a 22 kAIC main breaker, acts as service entrance equipment in conjunction with a utility meter and a 200A Eaton braker (CSR25K).
REMOTE MONITORING
- Enable remote monitoring, configuration, and firmware updates through the EG4 mobile app or online monitoring system.
SMART PORTS
- Includes load shedding, which disconnects loads during low battery voltage and reconnects on high voltage. Power shedding connects loads when at full SOC and PV flow and disconnects on low SOC or PV loss.
*When used with an Eaton 200A main breaker (model CSR25K)
