212, Table B.2 on page 213
Connect the inverter grounding connections to a ground bus bar, to a single
„
ground point, or to a common grounding point (impedance ≤ 10 Ω).
The neutral conductor of the network shall be solidly grounded; however,
„
this conductor shall not be used to ground the inverter.
It is necessary to use a copper cable with 10 mm
„
the same wire gauge as specified in

ground protection to be in accordance with IEC61800-5-1 since the leakage
current is greater than 3.5 mA AC.
