4 Product Overview
SMA Solar Technology AG
Operating manualSTP15-25TL-30-BE-en-1718
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. SMA ShadeFix is enabled by default. The
time interval of SMA ShadeFix is usually six minutes. This means that the inverter determines the
optimum operating point every six minutes. Depending on the PV system or shading situation, it may
be useful to adjust the time interval.
Surge Arrester Type II
Surge arresters limit dangerous overvoltages. Surge arresters of typeII can be retrofitted.
QonDemand 24/7
The inverter can supply reactive power by means of QonDemand24/7 covering the entire unit
circle around the clock.
IntegratedPlantControl
The inverter can display the Q(V) characteristic curve specified by the grid operator by means of
IntegratedPlantControl without measuring on the grid-connection point. The inverter can
automatically compensate equipment installed between the inverter and the grid-connection point
after having activated the function (for information on the system configuration refer to the Technical
Information "Integrated Plant Control" at www.SMA-Solar.com).
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.
4.4 LED Signals
The LEDs indicate the operating state of the inverter.
LED Status Explanation
Green LED glowing Feed-in operation
If an event occurs during feed-in operation, an event mes-
sage will be shown in the communication product (see
Section10.1, page55).
flashing The conditions for feed-in operation are not yet met. As
soon as the conditions are met, the inverter will start feed-
in operation.
