Hello,
Could you say what is the methodology for calculating the minimum voltage for MPP??
I add print screen for calcuation made by PVSol for Fronius ECO 27 and LONGi HPH 320 (both products from build-in database)
Why the min MPP is so low?
My reasoning:
Tvoc = -0,286
deltaT = 70-25 = 45
45*(-0,286) = ~ -13%
Vmpp = 33,9
Vmpp at 70°C = 33,9 - (33,9* 0,13) = 33,9 - 4,41 = 29,49
20*29,49 = 589,8
Calculation from Fronius Solar Configurator:
