Hi,
We are building a carport structure for solar panels. I understand this falls under a "separate structure" for NEC grounding. I am thinking to use a 8ftx5/8" ground rod. My question is, do I need 2? Not following code on that easily.
Next we are getting called by plan check for the listing of our panels calls out "series fuse rating 20A". As of right now we have SMA string inverters that do not have fuses for strings. Plan checker says it will violate warranty on panels if series string fuses are not installed. Any thoughts on this? He needs a letter from the panel manufacturer saying they are not needed and he has never been provided that.
Thanks again!
