  • Version 001.004.006 
    • Contents of the Release: Bug Fixes 
    • Release Date: January 2021
    • Bug Fixes:
      • Fixed an issue that could cause the MATE3s to erroneously report inverter
        firmware version mismatch errors and incorrectly shut down the inverter when
        the mismatch report occurred.
    • Known Issues:
      • Satellite modems.  Systems using a satellite modem may lose connectivity to OPTICS RE.
      • Connection to OPTICS RE.  If your MATE3s does not connect to OPTICS RE 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 version 001.004.000, please check your calibration settings (particularly for FN-DC) to make sure they have not changed and that they are in range.
