Application Note: SolarEdge Fixed String Voltage,

The total power produced by the string is now 9x200W+40W = 1840W. Since the inverter still needs to maintain an input voltage of 400V, the input current to the inverter will now be 1840W/400V = 4.6A. This means that the DC bus current must be 4.6A. Therefore, the power optimizers of the 9 un-shaded modules will have an output of 200W/4.6A = 43.5V.
