DC Surge protection in Solar Systems

[joede11]

Has it become common practice, although not required by the NEC, to install dc surge protection in solar systems

Seems that way to me. But lightning strikes are relatively common in TX. Installing surge suppression devices may not be standard practice in other parts of the country.

It's not common in California. I'd say almost never done.

Where is the dc SPD typically installed?

I was wondering where the surge is coming from?

Are you talking about a lightning arrestor?

Yes, but at 1000V or less there called SPDs
