[Voc at -10°C with 1500Vdc central inverter]

Thank you unilhexio for both tips, very helpful.

The Albedo Settings is all i needed.

In my database there was no 1500Vdc modules. Then i've create some new ones, based on the market, and the simulations worked.

 

You can change the minimum temperature for absolute voltage in 'Albedo - Settings' dialogue.

In other term, if you are using a 1500 Vdc inverter, it would be more suitable to use 1500 Vdc PV modules...

[Voc at -10°C with 1500Vdc central inverter]

Hello,

I was trying to use a central inverter with the DC voltage concept around 1500Vdc.

During the system definition, PVsyst showed the message: "The array Voc at -10°C is greater than the absolute system voltage allowed for this module (i.e. V=1000V)".

Because of that i couldn't go any further in the simulation.

So, that's my question: the Voc at -10°C isn't a irrealistic value for some sites? I mean, the specific site is located in the brazilian northeastern, there, the minumum temperature is around 10ºC (positive), never less than 0°C.

There's a way to adjust this parameter to 5ºC, or 10°C, (i'm still being much conservative about operation), or make the simulator consider these instead -10°C in the operational conditions without modifying the module model?
