Photovoltaic system Surge Protection
PROSURGE® SPV series employ high energy Metal Oxide Varistor (MOV), and constructed with our patented thermal protection and arc extinguishing technology which ensure safe disconnection while faulty current or abnormal voltage happened.
They are recommended for used on the dc-side of the DC-AC inverter, and PROSURGE® SP series on the ac-side to protect AC mains power supplies. The number and location of SPV SPDs on the DC side depend on the length of the cables between the PV array and inverter.
These series include single pole, Y connection and V connection for various applications in worldwide Photovoltaic systems, while the Y connection configuration is consisting of three protective paths for both Common mode & Differential mode protection, and the V connection configuration has two protective paths for Common mode protection.
The SPV SPD should be installed as close as possible to the inverter if the length is less than 10 meters. If it is greater than 10 meters, two SPDs are necessary, and one should be located in the box close to the PV array, another is located in the inverter area.
PROSURGE® SPV series are fully comply with UL1449 5th edition as Type 1ca SPDs, and Class II/T2 SPDs per IEC/EN 61643-11/31.
Prosurge SPV series DC surge protective devices are also widely used for Electromobility, protect the charging infrastructure and electric vehicles from lightning and surge damage.
