Core Real-Time Calculations

Overview

The Core Real-Time Calculations is a Certified Product Point Template for Solar Farms which defines required normalized real-time performance calculations that scale, or aggregate several of the calculated points in the Core Real-Time Calculations template on the Inverter level. These points are required for the Bazefield installation to function properly across all core applications.

These calculations specifically translate OEM-specific signals into consistent indicators of operational state, availability, communication status, and event conditions. By abstracting vendor-specific complexities, the Core Real-Time Calculations enable unified fleet monitoring, reduce configuration overhead, and support consistent reporting and alarm management across Solar Farms with heterogeneous inverter technologies. This template is foundational for delivering reliable insights in mixed-portfolio environments.

Template Definition

The Core Real-Time Calculations is defined below.  Pertinent Expressions are provided for key calculations. Calculations are one of the following types:

  • 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.

Required for Bazefield Core Dashboard functionality

Optional for common additional data streams/sources
