Apr 1, 2025April 2025 — Implemented a critical Sungrow Charger Enable State and Phase Switching Bug Fix in the evcc repository. The changes address incorrect handling of the enabled state and phase switching, update the status mappings, and introduce a new enabled field to track operational status. Phase switching was simplified by removing unnecessary enable/disable calls, reducing race conditions and misconfigurations. The work is tied to commit 6aa6e27cb403e76bc1c57fe56e1aa9e5473b9a67 and resolves the issue (#20857). Overall, this delivers increased reliability for Sungrow charging, improved observability, and safer automation in EV charging workflows.

Mar 1, 2025March 2025 monthly summary for evcc (evcc-io/evcc). Focused on Sungrow inverter integration for improved energy optimization and reliability. Delivered two changes: (1) Inverter Battery Management Improvements replacing forced-mode with a max discharge cap to maximize solar utilization and reduce unnecessary battery discharge; (2) Inverter Battery Mode Reliability Fix ensuring the inverter returns to normal battery mode with maximum charge power applied (default 1060). These changes enhance business value by improving solar energy capture, extending battery life through prudent management, and increasing system reliability. All work aligned with Sungrow hybrid integration and is tracked via commits.
