Why have you kept the dc voltage rating of inverter similar to ac voltage rating? Isn't these two should be set according to the inverter dc/ac ratings?
You are actually not wrong! There is also a bigger mistake here, the 6.6 for DC is in V and the 6.6 for the AC is in kV. I don't know why ETAP didn't give an error here! The inverter DC rating can't be 6.6V :'D Let me explain how to get the DC rating in general: The DC rating is selected based on the maximum open circuit voltage. This can be done by taking the PV panel array open circuit voltage and multiplying it by a correction factor from the NEC based on the minimum temperature occurring in the location because as temperature goes down, the voltage increases. Finally, the inverter DC input rating will be equal to this value.
I have referred to datsheet for inverter ratings( have rough idea of system voltage to be around 1000 VDC). I am setting up DC input more than start voltage required as per datasheet. Although I have the VOC for PV panels, will try to go by how you suggested. Thank you. I have one more question, what about the DC power rating. Should it be set equal/more/less than the PV panel KWp output? For now, I am just letting ETAP back-calculate it as per the inverter's KVA rating.Although, I have read it should be set similar to PV panel power rating.Considering losses, can it be less than the pv panel output? This is kind of confusing me. And by any chance, have you covered protection-coordination studies for grid connected solar pv system? If yes, could you please share the link for the same? Thank you for the good work. 😊
Me encantó 😊esta pequeña muestra de Sistema fotovoltaico, cuánto cuesta el curso? PD: Sus videos tienes subtítulos en español, como aquel video que acabo de ver aquí?
Gracias. Yo no hablo español bien :) I think the subtitles are generated automatically by UA-cam. Unfortunately on my website, I don't have any subtitles :(
dear sir can we use Etap software In Hydro power plant In Generation sector or it can be link with scada system For Generation management system? kindlay make a lecture on how we can use Etap in Generation sector

Thank u soo much sir for this video, saved me a lot of stress, u just earned yourself 1 more subscriber💯
You are welcome 🙏 I am happy that the video was helpful for you.
Very informative and simple , love from PAKISTAN
Thank you brother ❤
love it mate. I have bought three of your courses so far.
All the videos are amazing....thanks.....if u make for relay cordination than its very helpful..
Sure I will brother :)
thank you so much sir.
love from Pakistan.
You are welcome brother ❤🙏
superb tutorial 👍
Thanks sir for this nice tutorial . please do tutorial in switching optimization as much as possible
Salam. thank you very much for the video. do you have any video regarding reverse power flow problem for this kind of system ?

Can the PV run in DC load flow and short circuit?
Sir, can we reduce distribution losses by placing PV array ????
Hello sir, is it possible to simulate DC-coupled PV system in etap?
I will keep it in my mind, I saved a screenshot for your comment for future lessons
@@EngrAhmedMahdy Thank you sir

kindly discuss about different source plant to same load, ex., power from GRID and power from DG source or other source to same load
can you export pictures to PVs?
Yeeahhh... This is what I wanted.
I am happy that the video was helpful for you :)
hi sir, my etap dont have PV library, coul you share it, thanks
Hello sir, what about inverter harmonics!! How can I add it and!!
dear sir can we use Etap software In Hydro power plant In Generation sector or it can be link with scada system For Generation management system? kindlay make a lecture on how we can use Etap in Generation sector
Thanks sir
Welcome! :)
thanks a lot ahmed
You are welcome sir 👍🤗
Error 212: Source Gen base kV inconsistency with nominal kV. First value: 1259.52 kV, second value: 10.500 kV
How is this error corrected, please?
Please, give me the full name of this series using Etap? And is it for free ?
You can find the playlist on the channel named as Complete 2020 ETAP Course
