Photovoltaic surge protection for residential installation
For low power PV applications, i.e. residences and small offi ces, it is necessary to consider surge protecting the AC output of the Inverter that connects directly into the electric power grid as well as the DC input side of the Inverter fed by the PV modules.
PV surge protection for industrial and public building
Medium to large power PV systems can be installed on industrial and service facilities. In order to avoid very costly downtime and lost productivity resulting from a direct or indirect lightning strike, it is critical, and in some cases mandatory, to install surge protection at key points within your facility and its vital power and communication networks.
