I have a ground mounted array. 5 strings of PV. I'm putting DC isolators from Signature solar out near the panels.
I understand I must isolate the positive and negative wires of each string.
Using this:
I also have dc breakers just before the inverters like this:
Is this satisfactory ? Do I need anything else on the PV side of things ? I am thinking this gives 2 ways to shut off the high voltage DC if you need to work on the inverter. Also how are these DC isolators mounted in the field ?
Thanks for any help. This is my first system .
