The Sigenergy Sigen Hybrid Inverter (HYB) is a versatile, AI-powered energy management system designed for residential and commercial solar, energy storage, and EV charging. It supports fast 0ms backup switching, features IP66 protection for harsh weather, and enables seamless battery stacking for up to 48 kWh (residential) or MW-level (commercial) storage.
Main Features
- Seamless switchover, ensuring 0ms load-side disruption operation
- 150% overload for 10s, handling impact loads for smooth device startup
- Minimal size & weight in the same power range, ensures simple installation

The main difference between Sigen HYA and HYB inverters lies in their backup capability and off-grid functionality. The HYB series (50-110kW) is designed to support off-grid operation and seamless backup power during grid outages, while the HYA series (50-125kW) focuses on grid-tied solar applications, though both are battery-ready.
