DESCRIPTION
DC surge protective device protects against lightning surge voltages in the solar system (photovoltaic power supply system). These units must be installed in parallel on the DC networks to be protected and provide common and different modes of protection. Its installed location is recommended at both ends of the DC power supply line ( solar panel side and inverter/converter side), especially if the line routing is external and long.
High energy MOVs equipped with specific thermal disconnectors and related failure indicators.
