Ok so if you've read my previous post you know that I'm all messed up.
I'm not going to get into it all again so I'll just get right to the point.
My previous inverters, trandformerless ungrounded system, in the installation manual stated that you needed a grounding electrode. My interpretation of this is a continuous uncut wire between the grounding rods and the inverter. I know theres some exceptions to this but for the sake of what I'm getting at we'll ignore exceptions.
My new inverters the sunnyboy 7.7 transformerless, ungrounded, independent mttp trackers or whatever they are. The installation video only shows it being connected to the ground wire for the ac side. And it only refers to the grounding as Equipment grounding conductor. The difference between a EGC vs a grounding electrode is that a EGC can have splices in it just provided its sized correctly and the splices are made correctly? Am I correct in saying this?
Because I'm running up against 2 things , one being I can provide a grounding electrode by driving new rods and just running from there to the inverter. Uncut unspliced ect. However, if I do this, do these ground rods need to be bonded to the existing ac grounding system? If so can this bonding conductor have any splices in it?
Obviously I'd rather just use the ground wire coming off the ac side and be done with it. But it seems like over the last 8-10 years the standards have changed and it's very confusing. I know I had talked to my electrical inspector about this b4 and he definitely said that with my previous inverters that required a grounding electrode conductor that it needed to be uncut from the rods to the inverter but like I said the new one say EGC... any help would be great thanks.
