# Core Real-Time Calculations

## Overview

The *Core Real-Time Calculations* is a Certified Product Point Template for [PV Inverters](/product/docs/pv-inverter) which defines required normalized real-time performance calculations that scale, or transform several of the points in the [*Core Real-Time Data template*](/product/docs/core-real-time-data-solar-farm) (e.g. the collection “raw” points expected on all solar inverters). 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 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](/product/docs/edge-buffer)
- **Online Expressions:** Algebraic or logical manipulations of input data done on the central Bazefield data engines (typically on a [storage node](/product/docs/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](/product/docs/storage-node).

Details on the Point Names, Descriptions, and Types are below.

| EVENT-NotGenerating | If it's daytime and the inverter is not generating, and it's not due to low irradiance. | Calculation (Interval Exp.) | 300 s |  |  |
