Sonnen Buddy

Boost your sonnen experience with a more detailed, real-time view of your energy flow — and the ability to change your system configuration directly from the app, using your installation's built-in API. That includes charge events, and much more.

The live view complements the "my sonnen" app you already know by adding utilization of your PV panels, battery, and inverter. You provide your panel capacity, and the app reads your system's limits — including battery capacity, battery max input/output, and inverter max output. By calculating and displaying utilization right in the app, you can easily spot bottlenecks in your energy flow.

Set up schedules (charge events) to charge your battery from the grid — for example at night — or prevent battery discharge, all through a simple, intuitive interface. Change the operating mode, enable weather forecast charge management, and more.

Sonnen Buddy Premium unlocks capabilities for users who want even more control:

• Favorite schedules — apply your favorite schedules with a single tap. • Customizable real-time data — build your own view from the full range of data points your sonnenBatterie exposes. • Home screen widget — keep an eye on your schedules right from the home screen. • Lock screen widget — see your battery charge at a glance. • Manual mode — take direct, granular control for advanced use.
