Solar newbie, 2 questions on grouding and series vs parallel
Hi, I'm installing the Renogy 400W premium kit off-grid with 2000W inverter. Couple questions...
1. For grounding the inverter, is it okay to connect to my home's existing ground wiring, or do I need to have it on its own ground rod?
2. Series vs Parallel: The 400W kit diagram shows the panels connected in series, yet I have seen many references in Renogy videos that series connections are for 24v systems. Mine is 12v. So the info is a bit confusing. If I connect my 4 panels in series, is that suitable for my 12v system?
Thanks in advance!
