Nowadays, Photovoltaic systems (PV System) 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 PV system size. Where lighting occurrences are frequent, unprotected PV 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.

PROSURGE has developed a high performance but low cost solution for the industry of PV/DC power electronics, a surge protection module PVTMOV which is size optimization and space efficiency, will be easy integrated on printed circuit boards (PCB) and close to sensitive electronic element inside device, to minimize the potential impact of lightning events.

PCB Mount SPD Module for DC/PV Solar

PVTMOV is PCB solderable module, especially for inverters, PV combiner boxes, converters application etc.

PROSURGE® PVTMOV employ high energy Metal Oxide Varistor (MOV), and constructed with patented thermal protection and arc extinguishing technology which ensure safe disconnection while faulty current or abnormal voltage happened. It is generally known that the metal oxide varistor (MOV) is an ideal component for limiting surge voltage and current as well as for absorbing energy, but MOV may go into thermal runaway and result in short circuit due to sustained abnormal voltage (TOV) or end of life, that may cause fire hazard and significant losses to customer. Prosurge® surge protection modules have comprehensively improved the safety performance and proven to be excellent fail-safe and self-protected protective devices because of patented technology.
