* AS4777.3: If DRM support is specified, the inverter may only be used in conjunction with a Demand
Response Enabling Device (DRED).
CEI0-21: only permitted with external decoupling protection.
C10/11:2012: only possible if the three-phase line-to-line voltage is 400V.
IEC61727/MEA: applies only to the STP9000TL-20.
EN50438: does not apply to all national appendices of EN50438.
IEC62109-2: This standard requires that either the multifunction relay in the inverter is used as fault
indicator or that the inverter is connected to SunnyPortal and that the fault alert is activated in
SunnyPortal.
NRS97-2-1: This standard requires a separate label be attached to the AC distribution board to
indicate the AC-side disconnection of the inverter in case of a grid failure (for further details, see
NRS97-2-1, Sect. 4.2.7.1 and 4.2.7.2).
