  • Version 001.004.001 
    • Contents of the Release: Bug fixes and Enhancements
    • Release Date: February 2019
    • New Features:
      • Redesigned replay system for enhanced performance and stability.
        NOTE:  The redesigned replay feature is not compatible with the previous replay  feature.  After updating the firmware, the MATE3s will delete any existing replay files from the SD card.  The new replay feature currently supports seven days of replay data.
    • Bug Fixes:
      • Fixed multiple issues that caused calibration values to be incorrect and out of range.
      • Fixed CRC calculation issue that could cause failure of certain OPTICS RE messages and of uploading replay files.
    • Enhancements:
      • Added Event LED notification for charge controller (CC) ground fault (FM100 models only).
      • Added exclamation mark fault indicator next to CC icon on the Home Screen for:
        - Arc fault (FM100-300VDC-AFCI model only)
        - Ground fault (FM100 models only)
        - Rapid shutdown / input fault
      •  Removed support for previous AC Coupling feature (the ROCB version, not the relay version).
    • Known Issues:
      • Calibration. When updating from 1.4.0, please check your calibration settings to make sure they have not changed and that they are in range.
      • 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.
  • Version 001.003.001  
    • Contents of the Release: Bug fixes and Enhancements
    • Release Date: August 2018
    • Bug Fixes:
      • Fixed an issue that could cause the Wizard to incorrectly set voltages and currents in Radian E model inverters.
      • Fixed an issue that could cause the battery voltage calibration factor to exceed the upper limit.
      • Fixed an issue where the generator would not start unless the inverter was in 'On' mode only.  Now the inverter can be 'Off', 'Search', or 'On'.
      • Fixed an issue where 'Generator Total Run Time' hours in OPTICS RE did not match what the MATE3s displayed.
    • Enhancements:
      • Removed RoseWater server selections.

  • Version 001.003.000
    • Contents of the Release: Bug fixes and Enhancements
    • Release Date: June 2018
    • Bug Fixes:
      • Fixed issues with MATE3s connectivity to OPTICS RE that would cause connections to drop, large data spikes to appear, data stream and ModBus communication to go down periodically, DHCP enable/disable to not work correctly, and inverters getting deselected in OPTICS RE.
      • Fixed issues with the internal Web page not loading, and conformed internal Web page version number to the firmware release version number for consistency.
      • Fixed issue that caused a large number of on-site change events to post.
      • Fixed issue that caused a firmware update error to appear in Event History.
      • Fixed issue that caused FLEXNet-DC "Charge Parms Met" event to not post.
      • Fixed issue that caused saved settings of Upper Voltage Limit value of 256 and 258 to produce 0 and 2 respectively when restored.
      • Fixed issue that could cause Setup Page Hold and Delay Settings to be off by a factor of ten.
      • Fixed issue that could cause the AC Input LED to not light when AC input power is present.
      • Fixed issue that could cause the GMT timestamp to be improperly set on certain startup conditions.
      • Fixed issue that could cause very large numbers to appear in AC Input Current.
      • Fixed issue that could cause distortion of characters in the LCD.
      • Fixed issue that could cause a mismatch of settings for AC Amps between the status screen soft key and the Inverter AC Input and Current Limits settings.
      • Fixed issue that could cause settings to revert to pre-load of a GIP file when MATE3s is power-cycled.
      • Fixed issue that could cause settings changed locally on charge controllers (or while the charge controller was not connected to OPTICS RE) to not properly update OPTICS RE.

      • Fixed and improved replay functionality.
      • Fixed an issue the might disable the update soft key when a FM-100 is in the same system as a non-FM charge controller.
