The multi-function relay is suitable for use in the following SMA inverters:
• SB 3000TL-21, SB 3600TL-21, SB 4000TL-21, SB 5000TL-21
• WB 3000TL-21, WB 3600TL-21, WB 4000TL-21, WB 5000TL-21
• SB 2500TLST-21, SB 3000TLST-21
• STP 8000TL-10, STP 10000TL-10, STP 12000TL-10, STP 15000TL-10, STP 17000TL-10
• STP 15000TLHE-10, STP 20000TLHE-10, STP 15000TLEE-10, STP 20000TLEE-10
Use the multi-function relay only for one of the indicated purposes. Any other use may result in
personal injury or property damage.
For safety reasons, it is not permitted to modify the product or install components that are not explicitly
recommended or distributed by SMA Solar Technology AG for this product.
The enclosed documentation is part of this product.
• Read and adhere to the documentation.
• Keep the documentation in a convenient place for future reference.
Application
(operating mode)
Description
Fault indication/FltInd The multi-function relay controls a display device which, depending on
the type of connection, either reports an error or the undisturbed
operation of the inverter.
Self-consumption/
SelfCsmp
The multi-function relay switches loads on or off, depending on the
power supply status of the plant.
Control via communication/
ComCtl
The multi-function relay switches the loads on and off via a
communication product.
Battery bank/BatCha The multi-function relay controls battery charging, depending on the
power supply situation of the plant.
Fan control/FanCtl The multi-function relay controls an external fan depending on the
temperature of the inverter.
Switching status grid relay/
GriSwCpy
The local network operator may require that a signal is transmitted as
soon as the inverter connects to the electricity grid.
The multi-function relay simulates the switching status of the grid relay
and trips a signal to the network operator.

2.2 Qualification of Skilled Persons
The work described in this document must be performed by skilled persons only. Skilled persons must
have the following qualifications:
• Knowledge of how an inverter works and is operated
• Training in how to deal with the dangers and risks associated with installing and using electrical
devices and plants
• Training in the installation and commissioning of electrical devices and plants
• Knowledge of the applicable standards and directives
• Knowledge of and adherence to this document and all safety precautions
2.3 Safety Precautions
Electric Shock
High voltages which may cause electric shocks are present in the conductive parts of the inverter.
• Prior to performing any work on the inverter, always disconnect the inverter as described in the
corresponding installation manual from any voltage sources on the AC and DC sides
(see inverter installation manual).
Burn Hazards
Some parts of the enclosure may get hot during operation.
• Do not touch any parts other than the lower enclosure lid of the inverter during operation.
Electrostatic Discharge
Touching electronic components can cause damage to or destroy the inverter through electrostatic
discharge.
• Earth yourself before touching any components.
• Avoid contact with components or plug contacts inside the inverter.

You can use the multi-function relay for various purposes:
The multi-function relay can be retrofitted, or installed in the inverter at the factory if specified in the
order.
Application (operating
mode)
Description
Fault indication/FltInd The multi-function relay controls a display device which, depending on
the type of connection, either reports an error or the undisturbed
operation of the inverter.
Self-consumption/
SelfCsmp
The multi-function relay switches loads on or off, depending on the
power supply status of the plant.
Control via communication/
ComCtl
The multi-function relay switches the loads on and off via a
communication product.
Battery bank/BatCha The multi-function relay controls battery charging, depending on the
power supply situation of the plant.
Fan control/FanCtl The multi-function relay controls an external fan depending on the
temperature of the inverter.
If the temperature of the inverter is 5°C higher than a specific
threshold set in the inverter, the fan starts automatically. If the
temperature of the inverter is 10°C lower than the threshold, the fan
stops automatically.
Switching status grid relay/
GriSwCpy
The multi-function relay switches simultaneously with the grid relay of
the inverter.
