High surge protection level: Effectively protects against surges up to 3.2 kV, adequate for most solar energy systems.
Wide voltage range: Designed for up to 1000 V DC, making it suitable for photovoltaic systems of various sizes – from residential to industrial solar plants.
Fast response (< 25 ns): Rapid response to surges reduces the risk of equipment damage, providing quick protection for sensitive systems.
CE certification: Confirms product safety and quality, important for the European market.
Compact design and easy installation: Suitable for installation in electrical panels with a DIN rail system, ensuring convenient setup and maintenance.
1-year warranty: Provides coverage against manufacturing defects, giving the user additional peace of mind.
Cons

Only for solar energy systems: The device is specifically designed for photovoltaic (solar) systems, so it may not be suitable for other electrical network protection needs.
Limited durability in extreme conditions: While effective against typical surges, additional protection may be required in areas with frequent and intense lightning strikes.
Limited resistance to very high surge voltages: Although the maximum protection level is 3.2 kV, certain industrial and commercial settings may require a higher protection limit.
The surge arrester is an ideal solution for protecting solar energy systems from surges. It not only effectively protects sensitive equipment from lightning and electrical disturbances but also ensures stable operation with a rapid response to dangerous voltage spikes. It is a reliable, certified, and easy-to-install protective device suitable for both home solar plants and industrial solar projects.
