Huawei Smart PV Safety Guidelines | C&I Safety Matters

Safety Always Comes First

Safety is the foundation of sustainable industrial development across the industry. We are dedicated to delivering comprehensive safety solutions that support your business at every stage

Why Is Safety Our Top Priority?

At C&I Fusionsolar, safety is more than a priority—it is a technical principle embedded in our solutions.
In complex C&I scenarios involving challenging firefighting conditions and densely packed personnel and assets, we prioritize safety to prevent incidents and injuries and protect employees, machinery, materials, and property.

The System-Level Active Safety

Enhanced safety is designed for DC (direct current), covering everything from small components and dependable cables to the trusted devices.

Module-level RSD ensures the reduction to safe voltage is achieved within 30 seconds.

Module-Level Isolation Detection enhances fault locating precision by 7 times.
Arc-Fault Protection expands detection range to 450 meters.

Industry-leading PV Ground-fault Protection shuts down the on-grid system within 15 ms during a ground fault.
Smart String Level Disconnection rapidly disconnects DC side faults in 15 milliseconds.
Smart Connector Temperature Detection monitors connectors and shuts down the system within 0.5s if an abnormal temperature is detected.

C2C Electrical-link Safety: Short Circuit
Prevention and Isolation

The electrical safety is rigorously guaranteed with protection
at every level, preventing short circuits.
