IT, Delta-IT:
When using in these systems, the grounding conductor monitoring must be deactivated and
an additional grounding connected to the inverter.
**
AS 4777:
If DRM support is specified, the inverter may only be used in conjunction with a Demand
Response Enabling Device (DRED).
EN 50438:
does not apply to all national appendices of EN 50438
IEC 62109-2:
This standard requires 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
