Sigen PV 50M1-HYA

Item number: C00658

Warranty: 5 years

The Sigen PV 50M1-HYA is Sigenergy's three-phase hybrid inverter for commercial and industrial solar systems where reliable grid-connected power generation and future energy storage (PV + ESS) expandability are important. The device has a battery-ready design, and multiple inverters can be installed in parallel without a separate data logger. Built-in AFCI arc fault detection and instant PV reverse connection alarm support installation safety and operational reliability. IP66 protection makes it suitable for outdoor use.
