With automatic shutdown at temperatures exceeding 100℃, it requires no setup, is compatible with any string inverter, and offers flexibility in positioning. The emergency switch unit allows for Manual Emergency Shutdown and responds to local or area grid shutdowns. - ![beny bfs a1 PV RAPID SHUTDOWN DEVICE SOLUTIONS]() ## How the solution works? PV RAPID SHUTDOWN DEVICE SOLUTIONS The diagram above illustrates a typical 2-to 1 configured BFS protected installation using four solar panels and two BFS-A1. One more thing on the rooftop is the connection of BFS-A1 and the button switch via a communication cable. ## FEATURES/ADVANTAGES - ![Beny BFS A1 A2 RSD Shutdown]() ****A complete RSD solution****     - Automatically shut down the panels upon detecting the inside temperature exceeding 100℃. - Automatically shut down the panels in the button switch box in case of AC power supply loss. - The firefighter can manually use the button switch to shut down the panels in case of an emergency. ## Case Study - ![rsd case 11]() Philippines with 1.2MW solar installation - ![rsd case 12]() Philippines with 1.2MW solar installation - ![rsd case 3]() Philippines with 200kwp solar installation - ![Festival Supermall Alabang Solar Rooftop 430322]() Festival Supermall Alabang Solar Rooftop 2.8MW - ![Festival Supermall Alabang Solar Rooftop1 430322]() Festival Supermall Alabang Solar Rooftop 2.8MW - ![Pampanga Philippines 1 3MW 1430322]() Pampanga, Philippines 1.3MW ## SPECIFICATION | Model | BFS-A1 | | | --- | --- | --- | | Maximum Input Voltage | 110V | 70V | | Maximum Input Current | 20A | 25A | | Maximum Power (Input 1 + Input 2) | 2200W | 1750W | | PV Input and Output Cables | 4.0mm² (12AWG) Cables + MC4 Connectors | | | PV Input Cables Length | 180mm | | | PV Output Cables Length | 1800mm | | | IP Protection | IP68 | | | Operating Temperature | -40°C to +85°C | | | Storage Temperature | -40°C to +85°C | | | Standard Compliance | EN 62109-1:2010, EN 61058-1:2018 | | | PV Connectors | 1500V MC4 Connector | | | DC Power Supply for Each RSD | | | | Voltage Range | 14V \~ 28V | | | Maximum Current | 15mA | | | Maximum Power | 0.2W | | | Power Supply Cables (Signal Cables) | 2×0.823mm² (18AWG) Signal Cables + Signal Connectors | | | Power Supply Cables Length | 1800mm | | | Mechanical | | | | Enclosure Material | Aluminum | | | Dimension | 118mm\*107mm\*28.4mm | | ## RELATED PRODUCTS - [![beny bfs a2 rapid shudown back]()
