Questions in inverter module database and output ac power of a solar inverter.

Hi there,

I am doing a research project on Solar PV plant modelling. I got the excel file of inverter parameters at sam.nrel.gov/sites/default/files/sam-library-cec-inverters-2015-6-30.csv

Certain queries I have, please answer if possible.

1. Where can I get AC Output power (Pac) generated by the inverters?


2. What is PDc0?

3. Is Vdcmax given in excel file the same as
VDC described in SANDIA Inverter model?


Thank you in advance.


Sincerly,
Nisarg.

Dear Nisarg,

The parameters in the CEC inverter library are for the Sandia inverter model, and you can find descriptions of the model parameters in the model's documentation, which is listed on the Performance Model documentation page:

sam.nrel.gov/performance

The library lists the rated AC power output of the inverters. You can run SAM to calculate the inverter AC power output for the inverter installed as part of a photovoltaic system.

Best regards,
Paul.
