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 disturbance sensor.
For this purpose, the multi-function relay switches the disturbance sensor 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 Technical Description
"Multi-Function Relay and OptiTrac Global Peak" available at www.SMA.de/en).
4.6 Feed-In Management
The Sunny Tripower is capable of utilising reactive power 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.
