    • Release Date: August 2021
    • Bug Fixes:
      • Fixed an issue that could cause phase loss and slave inverter shut down.
      • Fixed an issue that could cause MATE3S to lose event log entries between power cycles.
      • Fixed an issue that could block Home Screen navigation when SD card is being detected.
      • Fixed an issue that could cause MATE3S to report events with wrong timestamps in OpticsRE.
      • Fixed an issue that could set FNDC relay calibration out of bounds.
      • Fixed an issue that could set incorrect values in the profile wizard for FXR and GS inverters.
      • Fixed an issue that could cause MATE3S to report incorrect register settings when mode is either GridTied or GridZero.
    • Known Issues:
      • Satellite Modems. Systems using a satellite modem may lose connectivity to Optics.
      • Connection to Optics. If your Mate3s does not connect to Optics after updating the firmware, and you're sure your network connection is strong and stable, try running the firmware update again. This will trigger rebuilding certain internal files that may help clear the connectivity problem.
      • Calibration. When updating from 1.4.0, please check your calibration settings (especially for FNDC) to make sure they have not changed and that they are in range.
    • Enhancements:
      • Flash SD card icon every 1 second to indicate SD card busy state.
      • Improved data integrity between MATE3S and downstream devices.
