Sep 1, 2025September 2025 (evcc-io/evcc): Delivered Huawei LUNA2000 Maximum Charge/Discharge Power Configuration, adding configuration template parameters to set max charge and discharge power for Huawei LUNA2000 devices. This enables finer energy flow control, improved battery management, and safer operation when integrating Huawei storage solutions. The change enhances energy optimization and reliability for solar/storage deployments by allowing explicit power limits. No major bugs fixed this month; focus was on feature delivery, integration readiness, and groundwork for broader device-specific configurations.
