The Sigen Gateway C600-B is the business version of the C600 series and combines 600 kW of power with additional security and communication features. While the standard C600 is suitable for general applications, the C600-B is designed for installations requiring maximum reliability and continuous monitoring. The gateway features dual communication ports, redundant relays, and enhanced backup power management. In addition to the standard backup function (immediately taking over the power supply in the event of a mains failure), this gateway features black-start—the ability to restart the entire system from a completely de-energized state. This allows the system to restart independently without grid or external power supply assistance. The C600-B also supports features such as zero feed-in (preventing feed-in to the grid) and parallel configuration (multiple battery systems working together as a single unit). The IP65 housing is suitable for indoor and outdoor mounting.
