In countries like Germany, balcony-mounted solar panels are all the rage. But from breaker-masking to voltage mismatches, America’s grid isn’t ready for it—yet.
Neutral and Ground are bonded at the first point of disconnect, which provides two paths to ground in the event a ground is lost was my point. Not that there are somehow “two Earth’s”.
And that’s better than 3 Phase 230V in what way?
Lower voltage is less deadly.
Having a multi grounded approach provides multiple layers of safety for shorts.
Just to name a few.
If Voltage of AC is above 50V, it will break your skin and then the current and time kills you.

Multiple grounds? There’s only one ground. You’re walking on it.
120V/240V, Split-Phase – Center-tapped
120V/208V, 3-Phase – Wye
120V / 208V & 240V, High Leg – Delta
