Max Open Circuit Voltage

[Mark]

Ho is this possible below if you have 9 x Jink0 590Watt BDV panels installed. The VOC of these panels is 52.9Vdc and multiplied by 9 gives you 476.1Vdc, and not 519Vdc as per PVSol below:

Dear Mark,

Thank you for your inquiry.

Open-circuit voltage is temperature-dependent. This temperature dependence is defined by the temperature coefficient, which can be found on the module data sheets.

The configuration limits take into account a minimum temperature of -10°C, as encountered in temperate latitudes.

If you are planning a system in subtropical or tropical regions, you can adjust the lower and middle of the three temperature limits upwards. For example, if the outdoor temperature in Namibia fluctuates only between 9°C and 34°C throughout the year, you would set the lower temperature limit to 5°C and the middle limit to 20°C:
