About This Product

The Sigenergy 110kW 3 Phase C&I Hybrid Solar Inverter 8 MPPT IP66 is a commercial and industrial hybrid inverter designed for larger three-phase solar and battery energy storage installations. It provides 110kW rated AC output and supports high-capacity PV input, making it suitable for sites that need strong daytime solar generation with the option to integrate compatible Sigenergy battery storage.

This model uses eight MPPTs, giving installers good flexibility when designing arrays across different roof faces, string layouts or site conditions. It is built for outdoor commercial environments with an IP66-rated enclosure and smart air cooling, and it supports monitoring and communications through Sigenergy’s system platform.

Who This Product Suits

The Sigenergy 110kW 3 Phase C&I Hybrid Solar Inverter 8 MPPT IP66 suits commercial and industrial solar projects where three-phase output, battery readiness and scalable system design are required. It is a practical option for warehouses, factories, large workshops, agricultural sites, retail buildings and other businesses with substantial daytime energy use.

It is best suited to professional C&I installations using Sigenergy’s compatible energy storage ecosystem, especially where the customer may want to add or expand battery storage as site loads grow. The eight MPPT design also suits projects where roof space is split across multiple orientations or where array design flexibility is important.

Specifications Explained

The Sigenergy 110kW 3 Phase C&I Hybrid Solar Inverter 8 MPPT IP66 has a 110kW three-phase AC output and supports up to 220kWp of PV input, allowing a commercial solar array to be sized appropriately around site usage and design limits. The eight MPPTs allow separate tracking of multiple PV strings, helping the inverter manage different roof orientations or uneven generation conditions more effectively.

The inverter is battery-ready for Sigenergy SigenStack systems and supports high charge and discharge power for larger energy storage applications. It has a maximum DC input voltage of 1,100V, a wide MPPT operating range, low harmonic distortion, and a power factor range suitable for commercial grid-connected operation. Protection features include arc fault detection, DC reverse polarity protection, residual current monitoring and anti-islanding protection.

Summary

The Sigenergy 110kW 3 Phase C&I Hybrid Solar Inverter 8 MPPT IP66 is a high-capacity C&I hybrid inverter for businesses wanting a scalable three-phase solar and battery-ready platform. Its 110kW output, eight MPPTs, Sigenergy battery compatibility and IP66 outdoor rating make it well suited to larger commercial installations where flexible array design and future energy storage integration are important.

For installers, the main appeal is its combination of high PV input capacity, commercial-grade protection features, and integration with Sigenergy’s wider C&I storage and monitoring ecosystem.

Further Information From The Manufacturer
