6.4 Grounding the Inverter
Due to the transformer-less design of the inverter, neither the DC positive
pole nor the DC negative pole of the PV string can be grounded.
6.4.1 Grounding System Overview
In this PV system, all non-current carrying metal parts and device enclosure should
be grounded (such as the PV array frame and inverter enclosure).
When there is only one inverter in the PV system, ground the PE cable.
When there are multiple inverters in the PV system, they can be multi-point
grounded. Connect PE cables of all inverters and the mounting metal frames of PV
array to the equipotential cable (according to the on-site situation) to realize
equipotential connection.
