Smart AI storage control proactively optimizes your battery charging. Instead of charging the storage to its maximum right at sunrise, the algorithm distributes the load strategically throughout the day.
Why do we use this control?
This function solves three central challenges of modern PV systems:
- Avoiding curtailment losses: In the event of active power limitations (e.g., the 60% rule), the AI keeps storage capacity free to capture the midday peak instead of losing it.
- Economic optimization: In markets with market-value remuneration (e.g., Austria) or negative exchange prices, feed-in is minimized by prioritizing battery charging during these favorable phases.
- Battery preservation: The battery spends significantly less time in the stressful 100% charge state, which increases its lifespan.
The process in three phases
- Morning (Safety Buffer): It ensures that a basic reserve for self-consumption (e.g., breakfast) is available or being charged.
- During the day (Dynamic Optimization): Charging is stretched or paused to leave room for the high-yield midday sun.
- Evening (Target Charge): The controller ensures that the storage is optimally filled by sunset to cover the night.
Compatibility & Combination
- Modular use: The function also works without a dynamic electricity tariff and offers benefits with any electricity plan.
- Teamwork with tariff optimization: If you use a dynamic electricity tariff, both AIs work together: the new function controls the solar energy, while the existing controller recharges cheap grid power when needed.
Frequently Asked Questions
- Why isn’t my battery charging at midday?
The AI is likely pausing the charging process to make room for the generation peak or to reduce feed-in at a later time when market values are low.
- Will my battery still get full?
Yes. The algorithm calculates the charging process so that the goal (full storage in the evening) is achieved, taking the weather forecast into account.
- Does this help against the 60% cap?
Yes, that is exactly what it is for. The storage serves as a buffer for energy that would otherwise be lost above the capping limit.
