To add your SolarEdge solar inverter to the Energy App you need an API key and a Site ID. The API key is a password for the data of your inverter. The site ID is unique to your installation.

Requirements and functionality

  • To add the inverter, Energy+ and a SolarEdge inverter with an internet connection are required.

  • The API data is available in the Energy app per 15 minutes. It is not possible to view the live data as with the HomeWizard kWh meter or P1 meter.

  • The data is only read from the moment of linking, there is no historical data.

  • API connections are subject to external factors, such as changes, stability, speed and accuracy of third-party devices and services. The user agrees to understand that HomeWizard can in no way be held responsible for the availability and correct functioning of third-party APIs.

Create an API key

In most cases you can create an API key as a customer. Follow these steps to create an API key:

  • Go to and log in with your SolarEdge credentials.

  • Click on Admin in the top bar.

  • Go to the Site Access tab

  • Go to Access control tab

  • Scroll to API access at the bottom of the page

  • Click on the Checkbox to agree to the terms and conditions

  • Click the New Key button

  • Click on Save

  • Copy the full API key and Site ID in a response to this email.

If you cant find these settings in your monitoring portal. It could be that only your system installer has access. You can find the installer of your system in the SolarEdge web portal dashboard. You can request a API key with an email directly to your installer with the above instructions:
