SPD small off grid system?

Adrian R · Sep 16, 2023

Hello everyone!

I need SPD with 2 poles on the pv side of the charge controller for smaller offgrid system. On the pv side: max Voc is 36vdc and other systems are max Voc 105-110vdc, what can you recommend?

Thank you!

Contact watts247.com or sigsolar and see what they have to offer.
What is your purpose? I’m assuming lightning arrestor?

Two MidNite solar SPD 115Vs? I run the 600v models - one for each string. You can see them as the enter the building at the top center here:

So, if I have Voc 110v on Midnite Classic, don't I need a 150V SPD for example? Instead of 600v SPD? Or did I get something wrong?

Another vote for the Midnite SPD's. Here's a link to several documents that you read to help you understand which one you need.
