Grounding and Off-Grid System
So I’m building a 100% off grid system in hopes of fueling my EV with it. I have encountered one last hurdle that I can’t seem to find the answer to or just haven’t been able to wrap my head around.
First of all my system consists of; 9 Canadian solar panels that are 320 watts each at 45 VoC for the 1st array (i intend to get more panels, as soon as I can for the 2nd array). The inverter is an EG4 12000xp v2 and the battery is the EG4 wall mounted indoor 314ah. The AC output from the inverter goes straight over to a Hubell Nema 14-50 receptacle using 6 awg cable with the L1,L2,N,G. I have a 8 gauge wire connecting the battery/conduit box to the ground buss bar in the inverter. I also have 6 gauge bare copper wire connecting all the panels together, over to a junction box where it switches to an 8 gauge thhn cable that runs down to the inverters ground buss bar.
The question is, can I then run a separate wire from the panels down to a ground rod and consider the system grounded that way? Or does the ground rod need to be connected directly to the inverter’s grounding buss bar for it to ground the system?
Sorry for the long post that I’m making even longer now but the is my first set up and needed some clarification on this since most of the videos I’ve watched don’t even bother with the grounding and the ones that do, don’t go into much detail for it. Thank you so much for your help.
