High-Voltage Surge Protection for Photovoltaic Systems
Photovoltaic arrays and their associated DC cabling can be exposed to transient overvoltages caused by lightning effects and electrical switching events. The Lovato SG2EDGK10M3R is designed for installation on the direct-current side of photovoltaic systems, where it helps limit transient voltages before they can reach sensitive equipment such as inverters and associated power electronics.
Its combined Type 1+2 protection, 1100 V DC rating, 20 kA nominal discharge current and 40 kA maximum discharge capability make the SG2EDGK10M3R suitable for coordinated PV surge protection. Replaceable cartridges, visual status indication and a remote signalling contact also simplify inspection and maintenance throughout the installation's service life.
Typical Applications
- Photovoltaic DC power installations.
- Commercial and industrial solar PV systems.
- PV combiner and string boxes.
- DC distribution equipment for solar installations.
- Protection of photovoltaic inverter DC inputs.
- High-voltage PV systems operating up to 1100 V DC.
