* IT, Delta-IT: When using in these systems, the grounding conductor monitoring must be deactivated and
an additional grounding connected to the inverter.
** EN 50438: does not apply to all national appendices of EN 50438
IEC 62109-2: This standard requires that either the multifunction relay in the inverter is used as fault
indicator or that the inverter is connected to Sunny Portal and that the fault alert is activated in
Sunny Portal.
NRS 97-2-1: This standard requires a separate label attached to the AC distribution board which
indicates the AC-side disconnection of the inverter in case of a grid failure (for further details, see
NRS 97-2-1, Sect. 4.2.7.1 and 4.2.7.2)
RD 661/2007, RD 1699:2011:Contact the Service for restrictions in specific regions(see Section 13,
page 55).
