NOTICE

Please ensure that you are downloading the correct version number. Each download contains a ReadMe text file that details the:

• Firmware Version Number
• Contents of the Release
• Release Date
• Additional useful information

Once downloaded, verify that the ReadMe text file contains the proper information regarding your Radian product. 

• Version 001.006.067 for GS8048A and GS4048A (Puerto Rico only)
  • Contents of the Release: Enables grid support settings specific to PREPA
  • Release Date: August 2018
  • Additional Information: This update enables the GS8048A and GS4048A to load the new PREPZ1R2.GIP file which sets the inverter to the grid support settings required by the Puerto Rico Electric Power Authority. The ZIP file includes both the firmware and GIP files; be sure to update the firmware before attempting to load the GIP file. 
    NOTE: Inverters installed outside of Puerto Rico do not require this update. An update to this firmware version must be performed with a MATE3s system display with 001.003.001 firmware or greater.
    
    
• Version 001.005.004 for GS7048E and GS3548E
  • Contents of the Release: Bug Fixes
  • Release Date: April 2014
  • Additional Information: Changed "Reconnect Delay" setting to not be affected by a Reset to Factory Defaults command, Corrected intermittent issue where a "Loose DC Neg Terminals" error could falsely be reported upon power-up, Changed operational limits of GridZero mode to start offsetting at 2 amps AC, cease offsetting at 1 amp AC and to require that the AC Input maintains a small amount of current to power the loads while offset is occurring

• Version 001.005.004 for GS8048A and GS4048A
  • Contents of the Release: Bug Fixes

  • Release Date: February 2013
  • Additional Information: Improvements to Auto Power Factor Correction to automatically correct power factor to grid or generator when source waveform is distorted by reactive loads, Improvements to AC Input transition to reduce arcing of AC input transfer relay (extending the transfer speed, particularly if reactive loads are present), Improved coordination between Master and Slave relay operations, Implemented individual power module limits where if “Module Select” is set to either “Right” or “Left” (dictating only one power module is to be used) then the “maximum” current limits for charging and selling are reduced by 50%, Fixed issue with AC Current Exceeds Max nuisance warnings by including 1 second hysteresis.
