Sigenergy C&I solutions

Companies in the photovoltaic sector are increasingly moving toward integrated solutions for the commercial and industrial (C&I) segment.

In this context, Sigenergy’s C&I solutions stand out for their comprehensive offering of advanced technologies that combine inverters, storage systems, and intelligent digital platforms ideal for optimizing energy autonomy and reducing operational costs.

Sigenergy inverters: a common platform for every C&I need

Sigenergy’s range of inverters for commercial and industrial applications is structured into three main series, all based on a shared architecture designed to ensure maximum efficiency, scalability, and ease of installation.

Key Features of Sigenergy C&I Inverters

4 to 8 MPPTs, with a maximum current of 40 A per tracker
Support for 2 PV strings per input, ensuring optimal flexibility in designing the PV field
AFCI protection with detection distance up to 500 meters for maximum safety
Efficiency up to 98.6%
Intelligent air cooling and IP66 protection rating
Integrated WiFi and Ethernet communication
Integrated Energy Management System (EMS), with support for connecting up to 100 units in parallel without external dataloggers

The Three Sigenergy Inverter Series

Sigen PV Inverter (50–125 M1): the base string inverter version, dedicated exclusively to photovoltaic production.
Sigen Hybrid Inverter (50–125 M1-HYA): enables integration with the SigenStack storage system via DC coupling, which reduces conversion losses and increases overall efficiency.
Sigen Hybrid Inverter with Backup (50–110 M1-HYB): in addition to integration with SigenStack, it includes a backup output for priority loads, with ultra-fast switching (down to 0 ms) to ensure uninterrupted operation.

SigenStack: Modular, Safe, and High-Performance Storage

The SigenStack storage system completes the Sigenergy offering with a modular, stackable solution designed for easy installation and maximum safety.

Storage solutions for Sigenergy C&I – key features

12.06 kWh LiFePO₄ modules stackable up to 21 units, for a total system capacity of over 253 kWh
Plug-and-play installation and fast commissioning
Multi-level fire protection system with smoke sensors and aerosol extinguishing technology
Intelligent air cooling and active balancing, eliminating the need for manual calibration
IP66 protection rating, ideal for outdoor installations

Thanks to its scalable architecture, SigenStack is perfectly suited to systems of various sizes—from small commercial sites to large industrial facilities.

An Intelligent Ecosystem for Energy Management

Sigenergy’s offering is completed by an advanced digital platform that connects inverters, storage systems, and control units into a unified, intelligent energy ecosystem.

Monitoring and Management with Sigen Cloud and mySigen

Through the Sigen Cloud platform and the mySigen app, users can:

Monitor production, storage, and energy flows in real time
Receive updates every 10 seconds
Automatically optimize consumption profiles with Sigen AI, the intelligent energy management assistant

The result is a complete, scalable, and interconnected system that simplifies design, enhances efficiency, and provides full control over energy usage.
