DC Surge Protection
Surge protection is available for common applications such as telecommunication, cell tower site, photovoltaic/solar and off grid application.
Solar Photovoltaic- SET
The PV sets are pre assembled protection solutions in IP65 installation housing. All surge arresters in the PV sets have temperature-monitored high-capacity varistors with optical fault warning and dynamic disconnect device.
PV-SET 1000 DC protects a photovoltaic string or a string input at the inverter between L+, L- and the ground/PE.
PV-SET 1000 DC/AC provides optimum protection to an inverter, since the pre-assembled solution protects the DC input and the AC outputs from surge voltages.
PV-SET 5ST/600DC is designed for the protection of an inverter.
