We estimate generation from weather data (MJ/m² → kWh) using system defaults and apply system efficiency, temperature derating, roof orientation and tilt, and inverter clipping. In the case of multiple roofs, the contribution of each array based on its position and power is aggregated; inverter clipping is then applied to the total if applicable.

You need to provide the inverter serial number and API token in the Inverter settings, then use the in-app "Test Connection" to validate. The API token can be found at www.foxesscloud.com (old version). You may be prompted to log into the new version, but there's no access to the API key there. Once logged in, click on User (head icon in top right) > User Profile > API Management > Generate API key.
