* To find out about restrictions in certain regions, contact the SMA Service Line.
** This standard stipulates that a special label be attached to the AC distribution to draw attention to the AC-side
disconnection of the inverter in the event of grid failure (for more details, see NRS 97-1-2, Sec. 4.2.7.1 and 4.2.7.2)
*** In order to meet the requirements of this standard, use of the fault indication relay must be activated in the inverter or there
must be a link to Sunny Portal with the fault alert via e-mail activated.
