PROFILE
Alex Ferrara
Alex developed core battery emulation and inverter communication features for the dalathegreat/Battery-Emulator repository, focusing on Sungrow SBRXXX CAN protocol implementation and runtime battery model configuration. Using C++ and embedded systems expertise, Alex designed end-to-end CAN message mapping, Modbus RTU over CAN support, and dynamic protocol handling for multiple battery models. The work included protocol refactoring, temperature data integrity improvements, and web UI enhancements for model selection. By validating data handling and optimizing backend logic, Alex enabled reliable monitoring, broader inverter compatibility, and scalable deployments. The engineering demonstrated depth in protocol implementation, firmware development, and maintainable code structure throughout the project.

Oct 1, 2025October 2025 monthly summary for the Battery-Emulator project. Delivered the core Sungrow SBRXXX CAN protocol for battery emulation and inverter communication, establishing the foundation for Sungrow inverter compatibility. Implemented end-to-end CAN message definitions with serial number generation, scheduling, and mapping logic to translate battery data into Sungrow protocol format. Completed a targeted refactor to improve simplicity and readability, and performed focused bug fixes within the feature (notably adjusting the 0x504 message sign for current). Removed an unnecessary 1.5s interval to optimize timing, reducing complexity. Overall, this work positions the project for thorough testing and eventual production use, enabling smoother integration with Sungrow inverters and paving the way for downstream features.
