Release Notes

New Features and Enhancements

  • Firmware upgrades during site visits is now optional for inverters that were already commissioned and not connected to an Energy Meter. 
    - After connecting to the inverter using SetApp, if a new firmware version is available you may decide to delay the upgrade to a later time by tapping Skip Upgrade. 
    - Note: SolarEdge recommends upgrading inverter firmware whenever a new version is released
  • The SolarEdge Sense Connect feature is now supported on Three Phase Commercial Inverters and Three Phase Inverters with Synergy Technology, with DSP1 1.20.xxxx and DSP2 2.20.xxxx  
    - Sense Connect enhances system safety through early detection and prevention of potential electric arcs at the connector level* due to improper connections or possible malfunctions resulting from wear and tear

    * S-Series (S1200) Power Optimizers only 
     
  • For ROW (i.e. all regions outside of Europe and North America), the ability to toggle the inverter fixed string voltage between 750V and 850V  is now supported via SetApp for the SE33.3K, SE66.6K and SE100K commercial inverters
    - Enables improved design flexibility with fewer strings, less cables/fuses and reduced BoS costs
    - Relevant for installations connected to the S1200 Commercial Power Optimizer, and only for specific inverter part numbers 
    - Read this App Note to learn how to toggle the inverter fixed string voltage
  • For European countries, the FCR-D-Down capability was added for Three Phase Commercial Inverters with SE DSP. Controlled and managed by Grid Services.  


Known issues and limitations

  • Three Phase Inverters with Synergy Technology (up to 120kW): Resetting the inverter during the Pre-Commissioning stage will shut down the system if the inverter is solar powered and a power bank is not connected
    Workaround: If a reset is required, reconnect the power bank before resetting
