Multi-Function Relay; Feed-In Management; Operating Parameters - SMA SUNNY TRIPOWER 15000TL Economic Excellence Installation Manual

SMA Solar Technology AG
4.5 Multi-Function Relay
The inverter may be equipped with a multi-function relay. The multi-function relay is an interface for
error messages or for controlling loads. Disturbances can be transmitted to a fault indicator. For this
purpose, the multi-function relay switches the fault indicator on and off. The multi-function relay can
control a load via a contactor. For this purpose, the inverter determines when the load is switched on
and off, depending on the operating parameters and measured values. You can configure the
multi-function relay for various operating modes (see manual of the multi-function relay available at
www.SMA.de/en).
Error message required by standards
In some countries, an error message is required by standards, e.g. IEC 62109-2.
In order to meet the requirements of IEC 62109-2, either the multi-function relay must be
used as a fault indicator and configured accordingly or a connection to Sunny Portal must
be available and the fault alarm must be activated in Sunny Portal (for information on fault
alarm via e-mail, see the Sunny Portal user manual at www.SMA-Solar.com).
4.6 Feed-In Management
The Sunny Tripower is reactive-power capable and can feed reactive power into the grid via the
setting of a default value for the displacement power factor (cos ϕ). Additionally, this inverter is also
equipped with advanced feed-in management functions, e.g. power limitation and dynamic grid
support. You can enable and configure these functions depending on the requirements set by the
network operator.
You can find detailed information on setting the parameters of these functions in the Technical
Description "Measured Values and Parameters" at www.SMA.de/en in the "Technical Description"
category for the respective inverter.
4.7 Operating Parameters
Various operating parameters control the functional performance of the inverter. Apart from the
country data set, the operating parameters of the inverter can only be adjusted using an
SMA communication product (information on the parameters can be found in the Technical
Description "Parameters and Measured Values" at www.SMA-Solar.com). You can adjust the country
data set before commissioning or within the first ten feed-in hours via two rotary switches in the inverter
(see Section 6.5.3 "Setting the Country Data Set and Language Using Rotary Switches" (page 47)).
