Over a three-month period, Salecker developed and enhanced battery management and API security features in the evcc-io/evcc repository. He implemented SOC-based charging controls and grid charging setup for Solis Hybrid S devices, enabling granular energy management through Go and YAML configuration. Salecker also introduced token-based authentication for myStrom chargers and meters, strengthening API security and improving onboarding with updated configuration templates. In addition, he delivered active battery control enhancements, allowing inverter overrides and new battery modes to optimize reserve and grid charging. His work demonstrated depth in embedded systems, device configuration, and backend development, addressing complex integration challenges.
In March 2026, delivered a major enhancement to active battery control in evcc, enabling overrides of inverter settings and introducing new battery modes to improve battery reserve management and grid charging. Implemented in the evcc repository with Solis Hybrid S integration via commit b10c9e74578852d80f3e4cb5ec92a87e1d06b157 ('Solis Hybrid S: better active battery control support (#27796)'). This upgrade enhances energy management reliability, reduces manual configuration overhead, and strengthens grid responsiveness. No major bugs fixed this month. Overall impact: improved energy autonomy, better grid charging behavior, and a foundation for future battery-management features. Technologies/skills demonstrated: inverter-level control, battery-mode design, integration work with hardware profiles, and detailed commit traceability.
