Sigenergy Gateway C120-6 Three Phase 120kW | Up to 6 SigenStor Units Backup

The Sigenergy Gateway C120-6 is a three-phase commercial and industrial energy gateway that enables seamless backup power, intelligent energy management, and generator integration across installations of up to six SigenStor Energy Controllers. With a maximum backup output of 120 kW across three phases, it is suited to small and medium commercial premises, larger residential properties, and multi-unit residential developments. Multiple breaker positions within the enclosure support a mix of SigenStor loads and other critical circuits. In the event of a grid outage, the gateway executes a 0 ms load-side transition — using Sigenergy's patented switchover algorithm — so connected loads experience no interruption. A 350 ms reverse power flow protection circuit safeguards both the grid connection and any connected generator. Smart Port connectivity enables centralised monitoring and control via the mySigen App.
