SolarEdge optimizers node for Node-RED

This is a node for Node-RED to scrape optimizer data from your SolarEdge cloud. You'll need your login data (username, password) and your site ID.

Installation

In your Node-RED directory:

npm install node-red-contrib-solaredge-optimizers

Usage

There are two nodes available with two different approaches to scrape data from the solaredge monitoring platform. Their usage will be explained below

solaredge-optimizer node

This node uses the data from the layout page of the solaredge monitoring platform. Here, only the power is available as parameter.

The following data has to be provided in the node to access the optimizer data:

• Username: Your username at https://monitoring.solaredge.com.
• Password: The corresponding password
• Site ID: The ID of your site.
• Time Interval:
  • Daily: Data of the current day
  • Weekly: Data of the current/last week

Optional inputs are:

• Time Zone Settings *: Choose the time zone of the output data timestamps:
  • UTC: Returns timestamps in UTC time
  • Local: Returns timestamps in local time zone
• Collect Additional Info: Scrapes the monitoring page for additional info such as description, type, serial number and manufacturer.
• Format For InfluxDB: Returns the data in a format so that it can be directly sent to an InfluxDB batch node from node-red-contrib-influxdb (tested for InfluxDB 2.0). An example flow is provided in examples/influxDbExample.json. Note: The Time Precision of the InfluxDb batch node has to be set to "Milliseconds (ms)"
• InfluxDB Measurement: In case Format for InfluxDB is checked, the name of the measurement.

The node will return the power in Watt for each inverter, string and optimizer in 15 minute intervals for the selected time interval.

solaredge-diagram-data-scraper Node

This node collects data from the diagram page of the solaredge monitoring platform for the current day.

The node needs the following inputs as required parameters:

• Username: Your username at https://monitoring.solaredge.com.
• Password: The corresponding password
• Site ID: The ID of your site.

Furthermore, optional parameters can be specified:

• Time Zone Settings *: Choose the time zone of the output data timestamps:
  • UTC: Returns timestamps in UTC time
  • Local: Returns timestamps in local time zone
• Collect Lifetime Energy: Scrapes the monitoring page for the lifetime energy at the time the node is triggered. Note: Lifetime data is not included in the diagram page and needs to be collected separately. Hence, lifetime energy returns only the current value and no time series data. Only for the selected component types lifetime energy will be returned.
• Format For InfluxDB: Returns the data in a format so that it can be directly sent to an InfluxDB batch node from node-red-contrib-influxdb (tested for InfluxDB 2.0). An example flow is provided in examples/diagramDataScraperInfluxDbExample.json. Note: The Time Precision of the InfluxDb batch node has to be set to "Milliseconds (ms)".
• InfluxDB Measurement: In case Format for InfluxDB is checked, the name of the measurement.
• Types: Select the type of components for which data shall be collected. At the time, this includes SITE, INVERTER, STRING, OPTIMIZER, METER, BATTERY
• Parameters: For each selected component type you can choose the parameters that shall be collected.

Sources / Credits

The scraping code from the layout page is based on this gist and translated from Python to JavaScript. The scraping for the additional information for the optimizer-node was inspired by the youtube video of meintechblog.de

Credits to @waltterli for finding a way to collect the data from the diagram page. This node would not exist without you :).
