About
Special PiggyBack (RS485)
Communication Between SMA Inverter and Solar-Log™
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. Please refer to the inverter manufacturer’s manual for additional information. The interface card is to be installed by qualified personnel only. Important Notice: Solare Datensysteme GmbH is not liable for damage arising from connecting the PiggyBack to the inverter.
