Smart PV Rapid Shutdown Device & AFCI Device smart RSD

Smart PV Rapid Shutdown & Safety Protection

The EO-PVMS-RSD Series is a smart PV safety protection device designed for high-voltage photovoltaic systems. Its dual-port design allows one device to manage two PV modules, helping reduce system cost while providing module-level safety protection and monitoring.The device integrates module-level rapid shutdown, AFCI arc-fault protection, data monitoring and PLC communication into a compact IP68 enclosure.When a shutdown signal is triggered, the PV output voltage can be rapidly reduced to a safe level, helping improve safety during system maintenance, emergency response and firefighting. PV Rapid Shutdown Device

Key Features

Module-Level Rapid Shutdown
Rapidly reduces PV output voltage to a maximum of 1 V in the shutdown state. Manual shutdown triggering helps improve maintenance and emergency safety.
AFCI Arc-Fault ProtectionSelected models provide module-level arc-fault detection for series and parallel arc faults, helping reduce the risk of PV system fire caused by electrical arcing.
One-to-Two DesignOne RSD device supports two PV modules, providing a compact and cost-effective solution for module-level rapid shutdown.
Module-Level Monitoring Collects key PV operating data, including voltage, power, energy generation and temperature, enabling more detailed system monitoring.
Long-Distance PLC Communication Uses bidirectional power line carrier communication with a maximum cable loop length of up to 1,600 m.
High Voltage & Outdoor Protection Designed for PV systems with a maximum system open-circuit voltage of 1,500 Vdc. The IP68 / NEMA Type 6P enclosure provides protection for demanding outdoor PV environments.
Flexible Installation Designed for installation on PV mounting rails. MC4 and QC4 compatible connectors are available, with cable lengths customizable according to project requirements.

Typical Application

The EO-PVMS Series can be used in utility-scale and commercial PV systems where rapid shutdown, module-level safety protection and PV monitoring are required.Typical applications include:

• Commercial & industrial PV systems
• Utility-scale solar power plants
• Rooftop PV systems
