66�1 Overview
SMA inverters do not have an integrated RS485 interface.
However, the following RS485 interfaces can be retrofitted
to SMA inverters:
•
Special RS485 piggyback card (by Solare Datensysteme GmbH)
•
Original SMA RS485 piggyback card (by SMA)
Both piggyback cards can be installed in "Sunny Boy" inverters (except for 3000/4000/5000TL-20
next generation) or
"Sunny Mini Central" by SMA. The SMA RS485 data module is required for the SMA -20 and Tripower
inverters.

Only use with Solar-Log™ devices.
Piggyback mixed mode
Inverters with special RS485 piggybacks and original SMA piggybacks or data modules can be used
together.
A diagram for wiring in SMA combined mode can be found in the appendix.
SMA Bluetooth mode
The Solar-Log™ BT model is compatible with Bluetooth enabled SMA inverters. The Solar-Log™ BT
models allow mixed mode operation (Bluetooth with RS485). Up to 7 SMA inverters can be connect-
ed.
Note
Refer to the chapters in the Installation Manual when exchanging SMA inverters.
