The Sigenergy Sigen PV HYA series represents powerful, 3-phase hybrid inverters (50kW–125kW) designed for commercial and industrial (C&I) applications. These inverters feature integrated Power Conversion Systems (PCS) for direct battery storage connectivity, boasting up to 98.6% efficiency, IP66 protection, multiple MPPTs, and rapid AI-driven arc fault (AFCI) detection.
Main Features
- Battery ready, easy upgrades to a PV + BESS at any time
- Smaller and lighter, easier installation and transportation
- Built-in EMS, supports 100 units in parallel without data logger
- Industry-leading 500m AFCI, top-tier safety across applications
- Fully networked communication, enabling rapid commissionin
- IP66 protection rating, ensuring worry-free outdoor deployment
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.
