Estimated Potential Power (Inverter)

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

Note

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

Technology

Solar

Remarks

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

Note

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

For more information about cut-in, see Irradiance-Cut-in.

This can be availability signal and performance signal, then depending on the following metadata:

  • Availability Irradiance Cut-In (W/m2) (Device metadata 15)

  • Performance Irradiance Cut-In (W/m2) (Device metadata 16)

Equation

Where:

Pp

is Potential power estimated.

P

is Power AC.

I

is Solar Irradiance Reference.

cut-in

is either Availability Irradiance Cut-In or Performance Irradiance Cut-In.

Pprevious

is Power AC from the first historically encountered 1h period with data from previous days.
