Sigenergy 100kW 3 Phase C&I Hybrid Solar Inverter with Backup (On & Off Grid) 8 MPPT IP66

The Sigenergy 99.9kW 3 Phase C&I Hybrid Solar Inverter with Backup (Sigen PV 99.9M1-HYB-AU) is a high-capacity, commercial-grade hybrid inverter engineered for large-scale solar and energy storage projects. Designed for on-grid and off-grid operation, this inverter ensures seamless, reliable power supply during grid outages, making it ideal for commercial and utility-scale installations where uninterrupted energy is critical.
With 99.9kW of hybrid capacity and eight independent MPPTs, the inverter optimises energy generation across complex solar array layouts while supporting high-efficiency conversion. Its modular and scalable architecture allows system expansion from kilowatt to megawatt levels using the Sigenergy Gateway, providing flexibility for growing commercial operations.
The inverter is fully battery-ready, integrating with SigenStor modules, SigenStack controllers, and Sigenergy’s intelligent energy management ecosystem. Advanced monitoring via wireless meters and cloud-based apps allows real-time system performance tracking, helping installers and operators manage large-scale solar + storage systems efficiently.
Backup and Reliability: The Sigen PV 99.9M1-HYB-AU features fast backup switchover, ensuring zero-delay continuity during grid outages, while 150% overload handling supports smooth equipment startup under high-demand conditions. IP66 protection and smart cooling ensure safe, reliable operation even in harsh environments.
Key Differences Between SigenStack Inverters:
SigenStack HYA Inverter: Grid-tied and battery-ready, but does not support off-grid operation or backup during grid outages.
SigenStack HYB Inverter: Designed to provide off-grid and backup power, ensuring continuous operation during outages (final specifications to be confirmed by Sigenergy).
