Personally, if you are using 10gauge solar cable, I would just run another 10gauge insulated cable and connect it up to the ground of your home system somewhere convenient.. ideally near where the solar charge controller and inverter is located so you can have similar cable lengths / resistances. Doesn't really matter if it "meets code" or not, because your system doesn't meet code anyway.So I should run a bare copper wire from the panels to the grid supplied ground or to the inverter? my mppt does not have a ground connection.
