Fox ESS Hub G2 200A Smart Energy Management System
The Hub G2 sits between the utility meter and the home and turns a Fox ESS PowerQ or US Series storage system into a whole-home backup solution. Its 200 A microgrid interconnection device isolates the home from the grid in under 20 milliseconds during an outage, while a built-in revenue-style energy meter removes the need for external CT and meter wiring.
