Overview
Standard battery systems typically discharge to cover household demand as soon as solar generation stops. However, under Dynamic Tariff Optimization, this is not always the most cost-effective strategy. If electricity prices are low now but forecasted to be significantly higher later, the system will temporarily pause discharging to reserve that energy for a high-price window.
Why is my battery not discharging?
When the system decides to hold battery power, the XENON UI provides specific "Intentions" to explain the pause:
Future Load Coverage: The system is saving energy to cover a high-cost consumption period later in the day. The UI will display the specific time interval when this consumption is expected to occur.
Grid Export Opportunity: The system is holding energy to discharge it into the grid later when feed-in prices are at their peak. The UI will indicate the expected discharge window.
Advanced Data & API
For technical monitoring, the API provides the Breakeven Price. This is the minimum price threshold required to make a discharge financially beneficial, accounting for efficiency losses.
