Modularity Takes Center Stage: Sigenergy and Frost & Sullivan Outline the Next Phase of Energy Storage

Sigenergy has partnered with leading consulting firm Frost & Sullivan to release the White Paper on Modular Energy Storage, which provides in-depth insights into emerging trends, technologies, and application scenarios for modular systems across both residential and commercial sectors.

As market awareness grows and technology continues to mature, modular energy storage is rapidly becoming the new industry standard. In the report, Sigenergy is featured as a key case study and is recognized for its pioneering modular architecture and strong market performance.

Modular Systems: Redefining the Future of Energy Storage

The report outlines the limitations of traditional energy storage solutions, such as rigid architecture, complex deployment, and poor scalability. In contrast, modular energy storage systems offer flexible configuration, faster installation, and enhanced safety, making them increasingly attractive to installers, EPCs, and end users alike.

In the commercial and industrial (C&I) sector, Sigenergy is recognized as one of the first companies to adopt a fully modular, stackable architecture. By enabling battery-pack-level optimization and seamless system expansion, Sigenergy’s solution enhances operational control, minimizes the impact of individual faults, and significantly simplifies operation and maintenance.

Built-In Safety: Fire Protection at the Pack Level

Safety is a core consideration in system design. The white paper emphasizes that modularity not only enhances deployment efficiency but also enables finer-grained safety strategies.

Sigenergy’s C&I modular system, SigenStack, features embedded fire protection at the individual battery pack level — a key innovation in the field. Each 12 kWh battery module includes a six-layer safety mechanism, combining temperature sensors, internal fire suppression, aerogel insulation, decompression valves, high-temperature-resistant insulating pads, and smoke detectors.

This design enables fault isolation at the module level, prevents thermal propagation, and allows the system to move from passive protection to proactive risk mitigation, representing a significant advancement over traditional cluster-based architectures.

Fast Deployment, Low Maintenance, and Scalable Growth

The white paper also addresses the high installation and maintenance costs traditionally associated with C&I energy storage. Sigenergy’s modular solution overcomes these challenges with plug-and-play connectors and simplified on-site stacking. Each system can be deployed in under an hour, without cranes or complex wiring.

Each 12 kWh module supports flexible system configurations, from 50 kWh to several hundred megawatt-hours, enabling customers to scale capacity based on real-world needs. The system is IP66-rated for outdoor use, maintenance-free, and hot-swappable within two hours, minimizing downtime and maximizing serviceability.
