Service Entrance Rated: 200A service entrance with 22 kAIC main when paired with Eaton CSR2200N (CSR25K) breaker (US only).
Smart Load Control: Four configurable smart ports for load and power shedding based on SOC/PV availability.
Remote Management: App/portal supports monitoring, configuration, and firmware updates.
Special Technology
Centralized ESS Control: Single point of connection for utility, backup/non-backup loads, generators, hybrid/AC-coupled inverters.
Hybrid Inverter Integration: Three hybrid ports (up to 90A per port) for EG4 12kPV, 18kPV, FlexBOSS18, FlexBOSS21.
Fast Transfer: ~25 ms transfer time helps maintain critical loads during grid events.
