New: inverter offline alerts. If your inverter stops sending data, Lumeron now lets you know in the app and by email, so you can reconnect quickly and keep your savings on track. This release also improves solar forecast accuracy (especially for shaded or more complex systems) and includes general reliability and stability fixes.
