Overview
The Core Monitoring KPIs is a Certified Product Point Template for Weather Stations which defines normalized performance KPIs that provide first-principles performance metrics for all vendors of Weather Stations. The metrics here specifically leverage the raw data in the Core Real-Time Data template (e.g. the collection “raw” Modbus TCP points expected on all weather stations) for calculated Insolation and Temperature values.
The Core Monitoring KPIs template is particularly valuable for operators and analysts who need reliable and consistent data to optimize the performance of their solar inverters and weather stations. By providing a clear framework for these calculations, the template helps maintain accuracy and consistency in data collection and analysis.
Template Definition
The Core Monitoring KPIs is based on a five-minute aggregation layer, formed from inter-related interval expressions (see below).
Scale Equations: Algebraic or logical manipulations of input data done on the Bazefield edge buffer
Online Expressions: Algebraic or logical manipulations of input data done on the central Bazefield data engines (typically on a storage node). Similar to scale equations in purpose, but done in the centralized architecture.
Interval Expressions: Algebraic, logical, or advanced manipulations of input data done within a pre-define aggregation interval (e.g. 5 minutes, 10 minutes, 1 hour, etc). These are typically done centrally on a storage node.
Details on the Point Names, Descriptions, and Types are below.
