Communication between SMA inverter and Solar-Log™

Special PiggyBack (RS485)

The special PiggyBack (RS485) is an inexpensive alternative to the standard SMA PiggyBack (RS485). It can only be used with the Solar-Log™ and requires 4-pin wiring. The device is supplied with power from the Solar-Log™ unit and therefore needs to have the proper connecting cable with a sufficient wire diameter and length. It is suitable for use with all SMA inverters, unless a data module, Quick module or Speedwire* is being used.For more information, see the inverter’s manual. The interface card is to be installed by qualified personnel only. Solare Datensysteme GmbH and Solar Data Systems, inc. are not liable for damage arising from connecting the PiggyBack to the inverter.

*In many countries, the designation ""Speedwire"" is a registered trademark of SMA Solar Technology AG.
