Regularly inspect the surge arresters and the enclosure to ensure continued protection and system integrity.
What to consider before purchase
Verify that your inverter supports 4 MPPT inputs
Ensure the installation location is suitable for a wall-mounted enclosure
Confirm that the 100A capacity meets your system's current requirements
Check local regulations regarding the installation of outdoor electrical switchgear
Usage recommendations: For optimal performance and safety, perform a visual inspection of the surge protection indicators periodically. If an arrester has reached its end of life, replace it immediately with a compatible Dehn component to maintain system protection.
