Hi all,

This is my simplistic wiring diagram for a to be solar system.

I feel like I need to do something with the earth, but not sure as the sunsynk videos don't really say.

And with the earth being from the grid neutral, but the neutral now being disconnected during a power cut.

Anyone got any ideas?

Or anything else I have missed?

Updated to show inverter earth rod for off grid running, and rewire of ups earth wiring.

Any thoughts?
