Dehn (DG M YPV SCI 150) SPD for combiner.

[kibi]

Hi

The title is a bit of a mouthful, but I am wondering if the SPD mentioned in the title would provide adequate protection for my small system that I am designing.
The Dehn SPD is going to go in the combiner box. The combiner won't see more than 70V from the array (for now) and a Classic 150 is planned downstream of the combiner.
The remote status signalling contacts of the Dehn is a feature that really appeals to me.

Many thanks.
