4.2 Type Label
The type label clearly identifies the product. The type label is located on the back of the product.
You can read off the following data from the type label:
• Device type (Type)
• Serial number
• Hardware version (Version)
• Device-specific characteristics
You will require the information on the type label to use the product safely and when seeking customer
support from the SMA Service Line. The type label must remain permanently attached to the product.
4.3 Multifunction Relay
You can use the multifunction relay for various purposes:
Error message required by standard
In some countries, signaling of errors is required by standards, e.g. IEC 62109-2.
This requirement can be met in one of two ways:
• Operate the multifunction relay in the operating mode Fault indication (FltInd) and
connect a display to the multifunction relay that signals an error or the undisturbed
operation of the inverter.
• Activate the error alarm in Sunny Portal (see the Sunny Portal user manual at
www.SunnyPortal.com for information on receiving error alarms via Sunny Portal).
This requires the inverter to be registered on Sunny Portal.
Operating mode of
multifunction relay
(Mlt.OpMod) Description
Fault indication (FltInd) The multifunction relay controls a display device which,
depending on the type of connection, signals either an error or the
undisturbed operation of the inverter.
This operating mode is set by default.
Self-consumption
(SelfCsmp) The multifunction relay switches the loads on or off depending on
the amount of power available from the PV array. If a battery is
integrated in the system, the multifunction relay will still switch the
loads on or off depending on the amount of power available from
the PV array, not from the battery.
Control via communication
(ComCtl) The multifunction relay switches loads on and off according to
commands transmitted by a communication product.
Battery bank (BatCha) The multifunction relay controls the charging of external batteries
depending on the amount of power available from the system.
