Power Failure Detection Device – New Standard for Energy Storage Switching
05/13 2026
Guangdong Renepoly Energy Technology Co., Ltd. has launched its self-developed power failure detection device, designed for uninterrupted energy storage systems. The device integrates sub-millisecond power failure detection and intelligent islanding control, enabling instant local response and physical isolation during grid anomalies. Critical loads experience seamless power switching, providing a highly reliable solution for coordinated grid-connected and islanded control.
Technology Highlights
Sub-Millisecond Response: Dual-core 240 MHz controller with voltage detection algorithm delivers local islanding signals in under a millisecond—no communication required.
Shock-Free Operation: Three-phase voltage and current monitoring with intelligent closing logic ensures smooth grid connection without inrush current.
Seamless Switching: Automatically isolates loads during grid faults and reconnects precisely after recovery, guaranteeing uninterrupted operation of critical loads.
Applications & Advantages
Modular design with 12–24V wide-range supply and RS485/Ethernet interfaces enables integration with on-site controllers and virtual power plants. Compared with traditional PCS+STS solutions, the device offers faster response, lower hardware cost, and simpler architecture. Suitable for PV storage, hybrid energy systems, data centers, semiconductor production lines, and hospital ICUs.
Outlook:
With large-scale deployment, Renepoly is now offering scalable engineering-grade seamless switching solutions, inviting industry partners for collaboration and verification.
