Is putting a lightning arrestor to protect my panels a good idea? See the picture

The MidNite's SPD looks very different, but if they do the same thing i am all set

Looks like a fine line between lightning attractor and redirector. Then there’s plain luck.

Looks like a different type of SPD but still similar to Midnite. The Midnite has a 100kA rating vs the 40kA which may not be important. That's how much current it can handle from what I gather.

Is that the exact unit you have? I'm assuming that Un and Uc have to do with the max system voltage and clamping voltage.

Just confirm that its ground terminal is hooked up to a ground or it won't do anything.
