@ericastar76 very cool stuff sisters. Looking forward to your "up and running" announcement. FYI : your copper (if you have copper) cold water line is the best ground you'll find and possibly easiest to attach a ground wire to.
unfortunately grounding to a copper cold water line doesn't always meet code requirements. My roof solar (15.64kw) generation system required 2 copper ground rods and the cold water ground and in addition my gas lines had to be bonded/grounded to the copper cold water line - after all of that I was almost expecting them to mandate a chemical ground rod :O
