Further Information From The Manufacturer

The Sigenergy 110.0kW 3 Phase C&I PV Solar Inverter (Sigen PV 110M1 AU) is a high-capacity commercial solar inverter engineered for large-scale commercial and industrial solar installations. Designed to deliver exceptional efficiency, advanced safety, and strict grid compliance, this inverter provides reliable performance for demanding solar projects.

With a maximum PV input power of 220kW and eight independent MPPTs (Maximum Power Point Trackers) supporting two strings per MPPT, the Sigen PV 110M1 AU enables highly flexible solar array design. This configuration helps maximise energy production across large systems, even when panels are installed on different roof orientations or experience varying levels of shading.

The inverter delivers a nominal output power of 110kW and maximum output current of 159.4A, making it suitable for high-capacity solar arrays. Its 98.6% peak efficiency ensures excellent energy conversion, helping commercial systems generate more usable power.

Engineered to meet strict grid standards, the inverter features low harmonic distortion (THDi < 3%) and a wide adjustable power factor range from 0.8 leading to 0.8 lagging. This makes it ideal for installations where compliance with grid regulations and power quality requirements is critical.

A broad MPPT voltage range of 160-1000V allows the inverter to perform efficiently across different solar array configurations while supporting modern high-power solar modules and longer cable runs. This flexibility helps maximise system performance even under partial shading conditions.

Built with safety and reliability in mind, the Sigen PV 110M1 AU includes rapid arc fault detection and protection, reducing potential system downtime and enhancing operational safety. Its durable IP66-rated enclosure and intelligent cooling design make it suitable for outdoor installation in challenging Australian environments.
