batcontrol -- Smart Control for PV Battery Storage

Anyone running a photovoltaic system with battery storage knows the challenge: the manufacturer’s built-in software decides when to charge and discharge – often without considering fluctuating electricity prices or actual self-consumption. batcontrol is an open-source alternative that puts the system owner back in control. Currently focused on Fronius inverters, it integrates with Home Assistant and optimizes charge and discharge cycles based on current market data and weather forecasts. Additional connectivity is available through evcc and MQTT.

bisQuITbox actively contributes to the development of batcontrol. The project thrives on a growing community – feedback, bug reports and contributions are welcome. Source code and further information are available on GitHub.
