This document lists the changes made to the MATE3 firmware from version 
003.017.001 to version 3.19.1, which rolls up the changes from 3.19.0.
 

Model Number: MATE3

Firmware version: 003.019.001 

Includes: Enhancements and bug fixes 

Release date: April 2019

 
********************************************************************************
                                3.19.1 Changes
********************************************************************************

New Features:

- None.


Enhancements:

- Improved replay functionality.


Bug Fixes:

- Fixed an issue where the internal web page displays values for AGS Load Start
  and Load Stop as ten times (x10) their actual value.

- Fixed an error that could cause intermittent incorrect CRC errors, which in
  turn caused issues with replay (file corruption) and Optics connectivity.

- Fixed an issue where the scaling of the high and low battery cut off 
  (HBCO/LBCO) delay times are ten times (x10) their displayed value.


Known Issues:

- Time Zones on the Mate3 include UTC-02:30 and UTC+10:30 in order to support
  DST through Optics. Setting the Mate3 to one of these time zones can have unpredictable results.

- Local Time updates: If you change the local time, date and time zone on the
  Mate3, the change will not appear in Optics until you power-cycle the Mate3.
  If you change the time zone via Optics, the local time, date and time zone
  will appear promptly in the Mate3.

- Issues causing the MATE to freeze after the lock button is pressed, freeze on 
  the splash screen, or enter a reboot loop when the splash screen is reached 
  are caused by corruption or failure of the NAND flash. These systems must be 
  sent to OutBack for service.  

- Upgrading from version 2.x.x can cause issues. To upgrade older firmware,
  follow these steps:

  1. Save the Mate3 configuration to the SD card BEFORE updating to new FW
  2. Update to new FW (will format internal flash memory for v.3.x.x)
  3. Update again with new FW (will copy screen files and WEB HTML files)
  4. Restore the configuration from the SD card



********************************************************************************
                                3.19.0 Changes
********************************************************************************

New Features:

- Added support for fractional time zones

- Added feature to synchronize System Name between Gateway and Optics

- Added feature to show the Mate3 IP addresses assigned through DHCP on both the
  Mate3 and in Optics



Enhancements:

- Improved replay functionality.

- Changed Mate3's 'Charge Termination Control' Default to OFF

- Changed Mate3 AGS Default to OFF




Bug Fixes:

- Fixed issues with Mate3 connectivity to Optics that would cause connections
  to drop, large data spikes to appear, and DHCP enable/disable to not work
  correctly

- Fixed an issue that would cause repeated "Firmware Mismatch" error messages to 
  appear in the Optics Event History

- Fixed an issue that would cause repeated "Time Zone Error" messages to appear 
  in the Optics Event History
  
- Fixed spurious Sell Current values by displaying all sell current below a  
  certain threshold as '0'

- Improved inverter firmware version reporting by disabling inverter FW version 
  matching validation while updating the inverter FW

- Improved consistency of values and icons in the Off-Grid and Back-Up MATE3 
  Home screens

- Redesigned the replay functionality for improved stability and scalability

- Fixed an issue that could cause an incorrect scale factor to be used when 
  calculating AGS Load Start kW and AGS Load Stop kW

- Fixed an issue that could cause incorrect inverter firmware or model mismatch 
  between master and slave inverters 

- Fixed issue that would cause slave inverter modes to not follow master mode

- Fixed several issues that could cause incorrect bar graphs or data spikes for 
  load or generator kWH on Optics

- Fixed issue that would show 0 volts AC in the AC Voltage Calibration screen 
  for Radian model E (export) inverters

- Fixed incorrect HBCO and LBCO delay times

- Fixed an issue that caused the Home Screen for Grid-Tied to not show the total 
  energy buy amount

- Fixed several DHCP issues that could cause DHCP to return one IP address for 
  multiple gateways on one network or to not correctly update IP addresses 
  obtained through DHCP

- Fixed an issue that could cause the Main Processor to indefinitely reset the 
  Ethernet Processor, which would in turn prevent connection to Optics



Other Changes:

- Removed FTP as it provided no benefit to users but could act as a security 
  vulnerability


  
Known Issues:

- Replay may not work on some systems. We are continuing to redesign replay
  for stability and functionality but may have a little more work to do to
  get it solid.

- Time Zones on the Mate3 include UTC-02:30 and UTC+10:30 in order to support
  DST through Optics. Setting the Mate3 to one of these time zones can have unpredictable results.

- Local Time updates: If you change the local time, date and time zone on the
  Mate3, the change will not appear in Optics until you power-cycle the Mate3.
  If you change the time zone via Optics, the local time, date and time zone
  will appear promptly in the Mate3.

- Issues causing the MATE to freeze after the lock button is pressed, freeze on 
  the splash screen, or enter a reboot loop when the splash screen is reached 
  are caused by corruption or failure of the NAND flash. These systems must be 
  sent to OutBack for service.

********************************************************************************
3.17.1 changes:
********************************************************************************

- Fixed an issue that could cause the Wizard to incorrectly set voltages and 
  currents in some inverter versions. 

- Fixed an issue that could cause the battery voltage calibration factor to 
  exceed the uppper limit.


********************************************************************************
3.17.0 changes:
********************************************************************************

New Features:

- Added support for SA-compliant inverters
 
- Added support for the new OutBack FlexMAX 100 charge controller


Bug Fixes:

- Fixed issues with Mate3 connectivity to Optics 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.

- 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 inconsistent display of generator hour meter.

- 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 Mate3 is power-cycled.

- Fixed issue that could cause settings changed locally on charge controllers
 (or while the charge controller was not connected to Optics)
  to not properly update Optics.

- Fixed issue that could cause AC Input Limits to display at 4x the actual 
  setting for up to three minutes before the display updates to show the correct
  value.

- Fixed issue in the Profile Wizard that caused the scroll value to roll over
  from 60 to 0 without allowing the user to scroll back to 60, so the user would
  have to scroll from 0 up to 60 to effectively scroll back one. 

- Fixed an issue that caused incorrect values to appear for input and output
  current and power for an FNDC. 

  
Enhancements:

- Updated internal Web page links to point to the new OutBack Power Web site
  resources.

- Improved replay functionality.

- Added support for data streams for FXR inverters.

- Improved some event history messages in Optics.

- Disabled Update key if no SD card is present or the SD card does not have a
  firmware image file. This prevents the inverter from shutting down in 
  preparation for an update when no update is available in the SD card.
  
- Improved FXR support to discern between Grid (AC1) input and GEN (AC2) for 
  reporting to Optics.
  
- Improved resolution of AC current settings and value display for FXR/Radian to
  two decimal places.

  

Other Changes:

- Removed "PF Priority" from the Multi-Function Parameter screen as it is no
  longer supported.
  

  
Known Issues:

- Unreliable data replay functionality. 
  Replay stores data on an SD card if the Mate3 becomes disconnected from 
  Optics. On reconnection, the Mate3 uploads the data to Optics. We have improved
  the replay functionality, but some users may see a gap in the backfilled data,
  graphs, and event history on Optics. If you see this situation, please notify 
  OutBack customer support.

- Issues causing the MATE to freeze after the lock button is pressed, freeze on 
  the splash screen, or enter a reboot loop when the splash screen is reached 
  are caused by corruption or failure of the NAND flash. These systems must be 
  sent to OutBack for service.  

Known Limitations:

- No Updates
