The Core Real-Time Calculations template contains calculations for inverter state and environment conditions. Details on the Point Names, Descriptions, Types, Expressions (if applicable), and Interval (if applicable) are below. Note: Scale Equations and Online Calculations are evaluated in Real-Time.

EVENT-NotGenerating | If it's daytime and the inverter is not generating, and it's not due to low irradiance. | Interval Calc | {If($[@EVENT-DaylightHours]==1 && $[@EVENT-Generating]==0 && $[@EVENT-NonGenDay-LowIrr]==0,1,0)} | 300 | |
MaxCapacityAvailable | Max power available if the inverter is available (IEC Operation State 2,3,4,5) then equal to the rated power attribute. | Scale Equation | |||
