I have been working on installing my 2000W Renogy Inverter Charger in my build and I am having issues grounding it. When connected to shore power, my AC outlet tester reads that everything is wired correctly. When on my house battery power, my outlet tester says that there is an open ground. I have the inverter ground from that little nut inside to the chassis and I have my inverter neutral going to the chassis as well but for some reason I am getting this error. Renogy told me to switch from utility mode to battery mode but this did not fix the issue. I know it has the automatic neutral and ground transfer but I'm wondering if my inverter might just be broken? Any help or suggestions would be appreciated. I tested my dad's RV when not on shore power and it was grounded so I know there is a way to ground completely but I don't know what that is.
