Series Strings

[esteban_24]

Good morning,

 

My name is Esteban. I am user of PVSOl 2016. I am trying to simulate a real fothovoltaic plant. This plant has strings of 20 modules in series, but I couldn´t found the option in PVSOL to configure 20 modules in series, the value maximum possible is 14 modulues in series. I attached some images, the first one is the schema of real plant and the other is my simulation. How can I configure strings of 20 modules in series?

 

Thanks. Best Regards,

Dear Esteban,

 

the solution to your problem lies in the inverter you have chosen. The new model by RefsuSOL Inc has a smaller voltage range than the older model distributed by REFU Elektronik GmbH. When you choose the older model, you can connect the modules as you would expect.

 

See the screenshot:

 

Also, I attached a project that corresponds to the schematics of the older version of PV*SOL that you provided.

 

Kind regards,

Martin
