Cascading Temperature Inverter

The Cascading Temperature signal on Inverters represents the ambient temperature for that specific inverter.

The ambient temperature is found by using a cascading order of data sources. If data does not exist for the primary source, the next data source will be used, and so on. The default behavior will prioritize the reference met masts configured on the inverter. For more information, see Remarks.

The order of the data sources can be configured per inverter. It can include any source of ambient temperature data. Please contact Greenbyte support to get help with the configuration.

Technology

Solar

Remarks

The default order of Irradiance data sources:

  1. Primary reference met mast(s)

  2. Secondary reference met mast(s)

  3. Tertiary reference met mast(s)

  4. Average ambient temperature of all met mast(s) on-site

  5. SolarGIS data

    Note

    SolarGIS is a marketplace add-on that adds ambient temperature data based on meteorological models.

Equation

The default data source order method works like this:

Cascading_Temperature_Inverter_-_Equation.png

Where:

Tca

is the Cascading ambient temperature

Tmetmast,primary

is the Ambient temperature from the primary reference met mast, or an average if several met masts are set

Tmetmast,secondary

is the Ambient temperature from the secondary reference met mast, or an average if several met masts are set

Tmetmast,tertiary

is the Ambient temperature from the tertiary reference met mast, or an average if several met masts are set

Tsite

is an average of the Ambient temperature taken from all met masts at the site

Tsolargis

is the Meteorological ambient temperature data from the SolarGIS add-on
