Potential Power Estimated (Inverter)

Description

Potential power estimated for inverters is only calculated when irradiance is above the irradiance cut-in and no power data exists. The calculation will then try to get data points for the same interval the previous day until all data gaps are covered.

Estimated potential power should generally be used as a last resort when no other data is available.

Note

The previous data is averaged on an hourly basis. So if there are 2 gaps in 10 min resolution, the average of the other 4 values will make up the value. If no values are found for that hour, Greenbyte continues to search at the same time-interval the previous day.

The maximum time period to search for previous data is 30 days.
