PSV(UL certify) Series

Nowadays, Photovoltaic systems range from small, rooftop-mounted or building-integrated systems with capacities from a few to several tens of kilowatts, to large utility-scale power stations of hundreds of megawatts, and in the meanwhile the potential impact of lightning events increases with Photovoltaic systems size. Where lighting occurrences are frequent, unprotected Photovoltaic systems can suffer repeated and significant damage to key components. This results in substantial repair and replacement costs, system downtime and the loss of revenue.

Properly installed surge protective devices (SPDs) will minimize the potential impact of lightning events. PRIME POWER SOLUSTIONS PSV 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. These series are of 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.

Usually, sensitive electrical equipments of photovoltaic system like AC/DC Inverter, monitoring devices and Photovoltaic systems array should be protected by PV surge protective devices (SPD).
PRIME POWER SOLUSTIONS PSV series are recommended for used on the dc-side of the DC-AC inverter, and PRIME POWER SOLUSTIONS PSV series on the ac-side to protect AC mains power supplies. The number and location of PSV SPDs on the DC side depend on the length of the cables between the Photovoltaic systems array and inverter. The PSV 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 closeto the Photovoltaic systems array, another is located in the inverter area.
