Automatic DC safety switch for photovoltaic installations. In case of fire or AC power loss on the inverter side, it automatically disconnects PV panels, effectively removing high DC voltage and ensuring the safety of firefighters and maintenance personnel.
✅ Supports up to 5 strings
✅ Automatic disconnection of PV panels when AC power is off
✅ Complete isolation between PV modules and inverter
✅ Fast response time – compliant with international safety standards
✅ High protection level – IP66
✅ Equipped with MC4 connectors for quick and safe installation
✅ Multiple switches possible for lower voltage (e.g. <120V))
✅ For rooftop and ground-mounted PV systems
✅ Safe DC disconnection during fire or AC outage
✅ Maintenance and service of PV installations
