Business Energy Gateway

A Comprehensive Backup Power Solution

Integrated with the Sigen Hybrid Inverter and SigenStack, the Sigenergy Gateway enables intelligent energy management with seamless backup power and 24/7 monitoring. It supports multi-unit parallel operation for flexible scaling from kilowatts to megawatts. With a DC-coupled microgrid design, the system simplifies deployment, improves efficiency, and delivers a reliable, cost-effective power solution for diverse energy applications.

Never feel the power failure

Thanks to Sigenergy patented power control algorithm, we have achieved the most powerful 0ms load-side disruption, ensuring a seamless transition to PV+ESS power supply for all loads whenever the grid power fails, thereby you never notice a power outage.

Effortless side-by-side installation

Sigenergy’s new C&I Energy Gateway features a modular, side-by-side design that allows flexible configuration and expansion from kW to MW-level systems, supporting up to 2.4 MW of backup power. Acting as the central hub for Sigenergy HYB inverters, it enables microgrid applications that enhance resilience, sustainability, and energy efficiency, paving the way toward a smarter, cleaner energy future.
