Sungrow Deploys Philippines’ First MW-Level Rapid Shutdown Project, Advancing Solar Safety

Sungrow, a global leader in PV inverter and energy storage solutions, has successfully implemented the Philippines’ first MW-level rapid shutdown project, marking a major advancement in solar safety technology. The project, a commercial and industrial (C&I) photovoltaic (PV) installation in Quezon District, Metro Manila, utilizes Sungrow’s SG125CX-P2 and SR20D-M PV rapid shutdown solutions.

Part of an 8.58 MWac installation by PHINMA, the deployment will supply sustainable energy to a logistics park and warehouse, ensuring both operational efficiency and enhanced safety measures. As a pioneering project, it sets a new standard for solar safety in Southeast Asia and reinforces Sungrow’s commitment to innovation in the region.

Enhancing Safety in High-Density Solar Installations

With many rooftop PV systems located in densely populated areas, the risk of fire hazards due to high DC voltage is a growing concern. To mitigate such risks, the National Fire Protection Association (NFPA) introduced rapid shutdown requirements in the 2017 National Electrical Code (NEC), prompting governments worldwide to adopt similar safety regulations.

The newly installed system at the logistics park spans a 200,000-square-meter manufacturing facility that operates 24/7. Given the high-density urban setting, implementing rapid shutdown technology was critical to ensuring compliance with safety standards and reducing risks associated with emergency voltage control.

Sungrow’s SR20D-M Rapid Shutdown Solution

Sungrow’s SR20D-M rapid shutdown device (RSD) features a 20-second shutdown time, adhering to UL1741/3741 safety standards. Additionally, the system’s AFCI (Arc-Fault Circuit Interrupter) technology detects and shuts down arcs within 0.2 to 1.5 seconds, minimizing fire hazards. The project, backed by FM Global insurance, ensures maximum reliability and compliance with local distribution utility (DU) safety requirements.

With over 6,000 Sungrow rapid shutdown devices installed, the system offers key benefits, including:

• Seamless integration with Sungrow’s PV inverters for a unified control system.
• 25-year warranty, guaranteeing long-term durability and efficiency.
• Bypass mode functionality, ensuring minimal disruption in case of faults.
• Easy installation, eliminating additional communication cables and simplifying system maintenance.

Driving Renewable Energy Growth in the Philippines and Southeast Asia

The rapid shutdown project aligns with the Department of Energy (DOE) Philippines’ Green Energy Auction Program II (GEAP II), an initiative aimed at expanding the country’s renewable energy capacity. The deployment of Sungrow’s RSD proceeded without disruptions to warehouse and logistics operations, maintaining business continuity while ensuring adherence to safety regulations.

Beyond the Philippines, Sungrow is strengthening its presence across Southeast Asia, with additional MW-level projects integrating its RSD technology in Thailand and Malaysia. The company’s commitment to advancing solar safety and innovation positions it as a key player in the region’s transition to secure and sustainable energy solutions.
