ASCII Import - Irradiance >1000 read as error


Recommended Posts

I am getting the following error when I try to import an ASCII file with measured irradiance and ambient temperature data:

The line number xxxx is invalid:

The field number 4 is in error.

It registers this error for every line where the irradiance value is greater than 1000 W/m^2. This is in PVsyst v5.55 only. I am not having the same issue when using v6. However, it does appear that in v6, the values greater than 1000 are being averaged back down to 1000, as my daily and hourly insolation values, as determined by PVsyst after the import, are not matching the actual measured insolation values from the import. In some cases, they insolation values are nearly 25% lower than actual.
