Radian Inverter PREPA Parameters

Post by TerraAlta2020 » Mon Jan 20, 2020 12:01 pm

Good afternoon:

We are trying to finalize in the PREPA parameters set up for an install in PR and we are having some doubts with the AHJ parameter requirements.

(Background: We have an installation of (1) Radian Inverter , Two (2) FM 100 , 32ea 340 watts PV modules and 22.8 kWh battery bank.- Latest firmware installed on all Outback components)

Both Radian Inverter (8048a) and Mate 3S have the latest firmware (as recommended by Outback Tech support during this case discussion particularly for the inverter (v1.6.70)) . In addition we loaded to the inverter the PREPA (Puerto Rico Energy and Power Authority) parameters contained on ZIP file PREPZ1R2 from your resources page.

The situation that we are having is that in order to comply with PREPA the following must be the parameters on the system (See attachment PREPA Parameters)

Upon loading the Outback GUI file for PREPA we issued a pdf report and the following parameters were obtained (See attachment Inverter Parameters)

If you can notice the parameters for frequency are as required but the ones for voltage do not match.

We tried to change the voltage parameters to align those with our local requirements but could not do it particularly on the over voltage ones (OV1 and OV2).

We are also including the Inverter Parameters Report file pulled from the Mate3S for your reference and support on this case. Also you can refer for more details to case #142920 with Tech Support.

Please advise on next steps as this is the only topic pending to close the loop with the agency.

Thanks in advance,

Eduardo Delgado

The PREPA settings should match the requirement, we'll look into that. I would recommend one of two things:

1) Try uploading the GIP file again, perhaps something happened in the process? OR
2) If you would like to quickly fix this, try looking at APP NOTE: Go to Page 6 under To Enter the Grid Support Menu You can access these settings and CAN change these. It should let you change it to the values you need.

Hi Gwendoly:

Thanks for your response.

We tried loading the GIP file several times with the same results as described before. In addition , we followed the procedure on the APP Note shared and could not change the OV parameters as stated on the message. At this moment we ran out of alternatives after following the procedures and calling tech services with the case number shared in the main message.

Please , let us know if there are additional steps that we must take to address this issue.

Saludos

If you look at the requirement again, it says % of nominal voltage. So 45% of 120 = 54V . 120% of 120V is 144V. The settings are correct.

Agree!!!!. I misunderstood the numbers (voltage instead of %).

Case closed!!!

Thanks for your support!!!

We recommend to add a column to include PREPA set of parameters on the Excel spreadsheet.

Thanks for your support!!!!

Agreed! I've already updated it, it should be on the website starting yesterday.
