The connection with Solax inverters has been updated since 17 September 2025. Did you already have a Solax connection before this date? If so, please add your inverter again in the app. This will ensure that everything is updated correctly.
Good to know: your old data will remain stored via the previous connection. You cannot delete this yourself at this time. New data will be automatically linked via the new connection.
