SMA ShadeFix

The inverter is equipped with the shade management system SMA ShadeFix. SMA ShadeFix uses
an intelligent MPP tracking system to determine the operating point with the highest output during
shading conditions. With SMA ShadeFix, inverters use the best possible energy supply from the PV
modules at all times to increase yields in shaded systems.
The time interval of SMA ShadeFix is usually 6 minutes. This means that the inverter determines the
optimum operating point every 6 minutes. Depending on the PV system or shading situation, it may
be useful to adjust the time interval.

Arc-Fault Circuit Interrupter (AFCI)

The type label of your inverter indicates whether your inverter has AFCI.
The arc-fault circuit interrupter is activated by default and can be deactivated on the user interface.
If the inverter is equipped with AFCI function, it supports AFPE (Arc-Fault Protection Equipment) for
arc detection and interruption. The AFPE protection covers the PV modules and DC cables of the PV
system connected to the DC input terminals of the inverter. A detected electric arc causes a brief
interruption of the feed-in operation.
An event message is entered on the user interface when an electric arc is detected. After a waiting
period of 10 minutes, the inverter starts automatically and checks whether the electric arc is still
present. If the electric arc is still present, the inverter disconnects from the utility grid again and the
process is repeated. After 5 electric arc detections per day (24h), the feed-in operation of the
inverter must be activated via direct or remote access via the user interface of the inverter.
The AFPE detection has 24 channels and one input port per channel.

SMA Smart Connected

SMA Smart Connected is the free monitoring of the product via the SMA Sunny Portal. Thanks to
SMA Smart Connected, the operator and qualified person will be informed automatically and
proactively about product events that occur.
SMA Smart Connected is activated during registration in Sunny Portal. In order to use SMA Smart
Connected, it is necessary that the product is permanently connected to Sunny Portal and the data
of the operator and qualified person is stored in Sunny Portal and up-to-date.
5.4.7

Fast stop function

The fast stop function is a digital input on the inverter via which the inverter can be disconnected
from the utility grid. It can be triggered by means of an external potential-free contact (break
contact or make contact). It can be configured whether the disconnection from the utility grid should
take place when the contact is open or closed.
The fast stop function is deactivated by default and must be activated in the inverter.
