STC Conversion
Functions
PV parameter setting function (α, β, κ)
・ Complying to IEC 60891 and JIS C8914/8919/8940
・ Conversion by measured Irradiance, Module temperature
Note) No conversion to AM1.5 by spectrum
PV Module Parameter Settings: (α, β, κ, Rs, module size)
Parameter setting save capacity: 70 settings
Automatically calculates STC conversion from the irradiance measured by sensor unit
pyranometer/reference cell and module temperature and display on graph.
・ Use fixed irradiance and module temperature values setup prior to measurement when
sensor unit is not connected.
