Florian Oehl developed a device template for the Marstek Jupiter C Plus battery storage system, integrating it into the evcc-io/evcc repository to expand the platform’s compatibility with solar-plus-storage deployments. He defined parameters for usage, Modbus communication, capacity, and maximum AC power, and configured rendering modes for PV and battery operation, enabling seamless management of battery storage alongside EV charging. The work focused on device integration and embedded systems configuration, utilizing YAML for template definition. By strengthening the device-templates framework, Florian accelerated future storage integrations and reduced integration effort for operators, contributing to broader market opportunities and streamlined deployments.
