Onboarding a Solar Site and a Weather Station to EnOS

This tutorial uses the example of a solar site and its internal weather station device to introduce how to use EnOS Onboarding Tool to connect sites and devices to EnOS Cloud via an EnOS Edge gateway.

Scenario

In solar sites, monitoring weather conditions is a common business scenario. Weather stations provide real-time readings of meteorological parameters such as temperature, humidity, wind speed, wind direction, rainfall, air pressure, and radiation at the site in real time. For solar sites, meteorological data provides important information for power forecasting, daily maintenance, and alarm overhaul, and is one of the guarantors of maximum power generation and revenue of solar projects.

Connecting the the weather devices to EnOS Cloud via EnOS Edge gateway is a convenient way to send instructions and control status to the devices remotely. Unattended, meteorological parameters can be sent directly to EnOS Cloud for display, storage, analysis and alerting through EnOS Industry Application Common Building Blocks to ensure the efficient operation of solar sites.

Tutorial Objectives

This tutorial enables you to:

• Onboard a solar site, a weather station via an EnOS Edge gateway using EnOS Onboarding Tool.

• Build the topologies of the site and its devices.

• Configure the connection of the devices and EnOS Edge.

• Map the measurement points of the devices to the measurement points of the EnOS models.

Prerequisites

• The operations in this tutorial use Site Onboarding. Therefore, ensure that the account has access to this menu. Contact the application administrator if needed.

• Onboarding Tool allows you to assign permissions to different roles for the different steps of Site Onboarding. This tutorial assumes that the onboarding process is performed entirely by the same role. Therefore, ensure that the account role has operation permissions for all processes on Site Onboarding. If necessary, contact the application administrator to obtain operation permissions. For more information, see Assigning Onboarding Process.

• Ensure that the current OU can create solar sites, weather station devices, and EnOS Edge gateway devices, and ensure that the associated business objects are assigned the appropriate model, manufacturer, and model. Contact your system administrator if necessary.

• Ensure that topology rules are in place that allow weather station devices to be assigned in solar sites. Contact your system administrator if necessary.
