The Core Monitoring KPIs template contains calculations for Inverter performance and production data. Details on the Point Names, Descriptions, Types, Expressions (if applicable), and Interval (if applicable) are below. Note: Calculation Models allow for more than single line expressions, see Calculation Models for the entire syntax.
