Discrepancy in Nominal AC Power

[Tina Dornbusch]

Hi, I am modeling a complex project using various different string lengths and solar optimizers. There are 48 inverter units (these are SolarEdge SE120s, so I am actually modeling 16 inverters with 3x 40kW units in each), and in the global system summary it accurately calculates 1920 kWac. However, in the report, the total power is noted as 1918 kWac. What is causing this discrepancy? Thank you!
