Can you help with this sizing calculation?
There are 191 SunPower Modules(SPR-E20-330-com), and each has 330W, So the total power DC KW = 63.03. The module has an open-circuit voltage=64.9V, a short circuit current = 6.52A, and a rated current=6.04A.
Open-circuit power generation with rated current = 64.9 X 6.04 = 74.87123 KW
After the low temperature at rated voltage calculation, the voltage at each module is 62.46V and rated current = 6.04, So the generated power = 72.05635 KW.
The preliminary design has an SMA inverter (STP-Core1 50-US S, 480V) with a maximum capacity of 75KW and efficiency = 97.5%.
As per the above calculation, I'm assuming this inverter (STP-Core1 50-US S, 480V) is undersized. I guess we will go for a larger size of the inverter.
I really appreciate any help you can provide.
