5.6 Grounding of Inverter
Because of the transform-less design of the inverter, DC positive pole and
DC negative pole are not permitted to be grounded. A permanent destroy to
the inverter may follows if otherwise.
All non-current carrying exposed metal parts of the equipment and other
enclosures in the PV power system should be grounded (e.g., PV arrays frame and
inverter enclosure).
