SOLAR GUARDIAN Smart Safety and Automatic Restart for PV Systems

Smart Safety and Automatic Restart for PV Systems SOLAR GUARDIAN The SOLAR GUARDIAN has been especially developed as a safety device for direct current (DC) photovoltaic installations. The DC switch is used to disconnect the connected strings of the installation in case of an emergency situation (for example in case of fire or overheating). In case of AC line interruption of the building, the SOLAR GUARDIAN automatically shutdowns the DC lines of the PV system thanks to the electronic board. The DC disconnect switch(es) is(are) automatically turned OFF if the AC power line is interrupted for...

Smart Safety and Automatic Restart for PV Systems SOLAR GUARDIAN Automatic OFF: The DC lines disconnect automatically if the AC line is interrupted for more than 3 seconds. Automatic ON: The DC lines reconnect automatically once the AC line is restored and stable for at least 5 seconds. Automatic OFF: DC lines disconnect and remain inactive after a manual remote command. Automatic ON: DC lines reconnect when the manual command is released, after verifying AC line status. Automatic OFF: DC lines disconnect if the cabinet temperature exceeds 100°C. Additional functions STATUS SIGNALING The electronic...

STRING BOXES

STRING BOXES DC STRING BOXES DIRECT CURRENT AC/DC STRING BOXES ALTERNATING AND DIRECT CURRENT AC STRING BOXES ALTERNATING CURRENT Discover more about our range of String Boxes MB Series. Visit our website or contact our technical team for further information.

The string boxes are made using specific components for the protection and wiring of a single string, two strings in parallel or two independent strings. Furthermore, it is possible to request customized configurations with wiring adapted to the type of PV system. Pre-wired string boxes with nominal voltage of 600 Vdc and 1000 Vdc are available, with overvoltage protection via type 2 Surge Protective Devices (SPD), overcurrent protection via fuse holders base (fuses included), and isolation via disconnect switches specific for DC-PV1 and DC-PV2 use categories (according to IEC EN 60947-3). The...
