SMA STP 15000TL-30 - Multifunction Relay

communication device and for a maximum of 4 inverters per SunnyPortal system. In large-scale PV
power plants, data transmission to the Internet portal SunnyPortal is carried out via the
SMAClusterController. You can access your SunnyPortal system from any computer with an
Internet connection.
Webconnect enables - for PV systems operated in Italy - the connection or disconnection of the
inverter to or from the utility grid and the specifying of the frequency limits to be used via
IEC61850-GOOSE messages.
RS485 Interface
The inverter can communicate via cables with special SMA communication products via the RS485
interface (information on supported SMAproducts at www.SMA-Solar.com). The RS485 interface
can be retrofitted and can be used in place of the SMASpeedwire/Webconnect interface in the
inverter.
Modbus
The inverter is equipped with a Modbus interface. The Modbus interface is deactivated by default
and must be configured as needed.
The Modbus interface of the supported SMA devices is designed for industrial use and has the
following tasks:
• Remote query of measured values
• Remote setting of operating parameters
• Setpoint specifications for system control
Grid Management Services
The inverter is equipped with service functions for grid management.
Depending on the requirements of the grid operator, you can activate and configure the functions
(e.g. active power limitation) via operating parameters.
SMA Power Control Module
The SMAPowerControlModule enables the inverter to implement grid management services and
is equipped with an additional multifunction relay (for information on installation and configuration,
see the installation manual of the SMAPowerControlModule). The SMAPowerControlModule
can be retrofitted.
Multifunction Relay
You can configure the multifunction relay for various operating modes. The multifunction relay is
used, for example, to switch fault indicators on or off (for information on installation and
configuration, see the installation manual of the multifunction relay). The multifunction relay can be
retrofitted.
