Mr. Zhang accentuated that harnessing Huawei's cutting-edge Smart PV Technology seamlessly combines digital and power electronics innovations, will significantly reducing hazardous incidents caused by unstable control systems, improper installation, and other factors, thereby ensuring a safer and more reliable rooftop PV experience for all.

The Huawei’s Smart String-Level Disconnector Technology (SSLD-TECH), enabling active DC disconnection and precise string-level isolation to ensure safety and reliability for power plants. Huawei FusionSolar emphasized on active safety whereby the AI-powered arc fault circuit interrupter (AFCI) arc fault locations within modules and discern electrical arc noise, effectively mitigating false alarms and detection gaps to ensure safety for customers.

Nevertheless, Huawei FusionSolar’s Smart Module Controllers are equipped with the module rapid shutdown function. Each module is linked to an optimizer to monitor its output, and in emergency situations, the rapid shutdown can be trigged by a power grid outage, disrupted communication with a remote emergency switch, or manually initiated via the DC switch, ensuring personal, electrical, and property safety.
