    Dear all,
    Please let me know about interfacing (RS485) up to 10 Sunny boiy (5000-US … ) converters.
    The information in the installalltion manual is not containing any useful information.
    The dealer here was not even aware of the existence of the monitoring feature.
    Do you provide any RS485 to Ethernet or WiFi Interfaces to get the raw data 7

      Walter, for the older US PV inverters, the RS485 piggyback card allows for daisy chaining the inverters. However, you need the discontinued Sunny Webbox to gather the SMA Data I from the RS485 bus to view and store. You may be able to find the Speedwire piggyback card for you inverters (SWPB-US-10), but they are restricted to specific Firmware versions. These cards provide data over Ethernet cables, but in SMA’s Data II+ format, so would not be “raw” data to be used directly, but could be sent to Sunny Portal. Please contact SMA service (1-877-697-6283) if you need more information about the supported firmware versions for the Speedwire Piggyback cards.
