Core Real-Time Data

Overview

The Core Real-Time Data is a Certified Product Point Template for PV Inverters which defines the standardized, minimum set of telemetry (e.g. time series points) Bazefield recommends for real-time monitoring of all solar inverters. The measurements in this template are at the Alternating Current (AC) level. These points ensure consistent data collection, improve interoperability across assets, and enable accurate reporting and analysis across your portfolio.

This point template provides a reliable baseline of real-time data expected from each PV Inverter modeled in Bazefield. The purpose is to:

  • Ensure consistent naming and normalization of critical telemetry available on all makes and models of PV Inverters

  • Streamline configuration for SCADA or historian data ingestion

  • Support cross-site and cross-technology data normalization

Template Definition

The Core Real-Time Data template contains standard data streams for inverter SCADA data, including key AC electrical measurements. Details on the Point Names, Descriptions, and Types are below.  The Core Real-TIme Data template specifically holds all the critical “raw” data expected from all solar inverter SCADA systems.  For solar inverters, the core-real time data points are often provided directly from an Modbus TCP interface provided by the OEM of the solar inverter.

Minimum Requirements

In most modern solar inverters, there will be a significant number points available beyond this list which are vendor or SCADA specific.  This list represents the minimum, common list of critical data often available in ALL vendors and SCADA systems.  Many of the points below are used directly in Bazefield core functionality, or core performance calculations.

Optional for common additional data streams/sources
