The intelligent AI battery control optimizes your battery charging in a predictive manner. Instead of charging the battery to its maximum capacity immediately at sunrise, the algorithm strategically distributes the charging process throughout the day.
Why do we use this control system?
This feature addresses 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 capacity available in the battery storage to absorb the midday peak instead of losing that energy.
- Economic optimization: In markets with market-value-based remuneration (e.g., Austria) or during negative spot prices, grid export is minimized by prioritizing battery charging during these favorable phases.
- Battery preservation: The battery spends significantly less time in the stressful 100% state of charge, which increases its service life.
The process in three phases
- Morning (Safety buffer): It is ensured that a base reserve for self-consumption (e.g., breakfast) is available or is being charged.
- During the day (Dynamic optimization): Charging is stretched or paused to leave room for the high-yield midday sun.
- Evening (Target charging): The control system ensures that the battery storage is optimally filled by sunset to bridge the night.
Compatibility & Combination
- Modular use: The feature also works without a dynamic tariff and offers advantages with any electricity tariff.
- Teamwork with tariff optimization: If you use a dynamic tariff, both AIs work together: the new feature controls solar energy, while the existing control system recharges low-cost grid power when necessary.
Frequently Asked Questions
- Why is my battery storage not charging at midday?
The AI is likely pausing the charging process to leave room for the generation peak or to reduce grid export during low market values at a later time.
- Will my battery storage still be full?
Yes. The algorithm calculates the charging session so that the goal (full battery storage in the evening) is achieved while taking the weather forecast into account.
- Does this help with the 60% cap?
Yes, that is exactly what it is designed for. The battery storage serves as a buffer for the energy that would otherwise be lost above the capping limit.
