Boost your sonnen experience by getting a more detailed real-time view of your energy flow and access to changing the system configuration (including charge events) directly from the app using your installations built-in API. The live view compliments the view you already know from the "my sonnen" app by adding utilization of your PV panels, battery and inverter. You provide the capacity of your panels and the app reads the limitations of your system including battery capacity, battery max input/output and inverter max output. By calculating and showing the utilization directly in the app, it makes it easier to spot bottlenecks in your energy flow. Setup schedules (charge events) for charging your battery from the grid e.g. at night or preventing battery discharge with a simple intuitive interface. Change operating mode or enable weather forecast charge management and a lot more. https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ ## Key features - Real-time energy flow view - PV panel, battery, and inverter utilization - System configuration adjustments - Charge event scheduling - Operating mode changes - Weather forecast charge management ## Pricing and in-app purchases Base price: Free. **Subscriptions** | Subscription | Price | Period | | --- | --- | --- | | Sonnen Buddy Premium | $22.99 | per year | | Sonnen Buddy Premium | $2.99 | per month | ## Recent user reviews (4 of 4) All indexed reviews: https://appshunter.io/ios/app/sonnen-buddy/id1627198189/reviews.md ### 4/5 — Great app *2025-11-13, version 1.02* Love the ease of this app to manage my Battery.
