I'm having issues with my new MPP solar LVX-6048 and haven't been able to find the solution in any of the other threads in this forum. It seems like whenever the inverter is using both the solar input and the AC input for something, that it causes a ground fault (the GFCI breakers in the subpanel that's powered by the inverter trip and my tesla wall charger shows that there's a ground fault). If I turn off the solar at the disconnect the ground fault immediately goes away, or if I unplug the AC input it immediately goes away. It also goes away if the inverter is in a mode that doesn't use the AC input for anything. The inverter seems to have an issue with using the AC input when it doesn't need to but that's another story (I currently have 10x as much solar coming in as power going out to the loads yet both the inverter panel and the app show that it's drawing from the AC input for some reason). I have tried jumping the AC input and output neutrals together but that didn't fix anything. Should I do the same for the AC input and output grounds? Any other potential solutions?
