seems like if I want to have AC input to charge batteries with grid power I need to remove the NG bond screw in my panel and use the AC input on different phases to keep a ground and the inverters happy. If I want to be completely off grid with no AC input for charging I need to install the NG bond screw in the panel and also add a earth ground but in either case I would leave the connection between the AC in neutral and AC out neutral. Would I be safe to use my main water line to connect a ground clamp to so that I have an earth ground? If I do it this way and decide to go back to using grid power for charging would I need to remove the ground going to water line so i don't have two grounds?

If I want to run completely off grid with no AC input I remove the neutral jumper wires, add the N-B screw back to my panel then what do I do for a ground? Does it just become floating like a generator or should I still ground it to my house? If I still need to ground it can I just get a ground clamp amd connect it my my water main next to the other ground clamp that is for the house?"
