Because of the large space requirements of the electrical phenomenon generators, PV surge arresters are especially vulnerable by lightning discharges during electric storms. These arresters ensures excellent performance solutions t with the international standards in order to ensure the reliability and efficiency of the photovoltaic system. PV surge arresters are not only installed by the house owners on their rooftop but also snobbish companies make than investments in shared systems, which are upright on large surface roofs, unused open areas or on traffic structures load.
