Sigen PV 125M1-HYA

Item number: C00663

Warranty: 5 years

The Sigen PV 125M1-HYA is Sigenergy's high-performance, three-phase hybrid inverter for commercial and industrial solar power systems, designed for stable grid production and, if required, easy integration of battery energy storage. The device is battery-ready, making it easy to expand into a PV + ESS system; parallel operation with multiple units is possible without a separate data logger. Built-in AFCI arc fault detection and instant PV reverse connection indication enhance installation safety and operational reliability. Thanks to its IP66 protection, it is suitable for outdoor installation, and its maintainability supports easy operation.
