+====== Victron MultiPlus 3000: Firmware v502 to v558 Changes ======
+Updating from firmware v502 to v558 introduces critical stability improvements and regulatory compliance features.
+===== Key Improvements =====
+==== Generator & AC Input (v556) ====
+Improved Stability: Significant enhancements to system stability for Charge and PowerAssist when connected to generators.
+Weak AC Input: In many cases, the system can now maintain a stable connection to generators without needing the "Weak AC" setting enabled, allowing for higher charge currents.
+==== Regulatory Compliance (v556) ====
+German §14a EnWG Support: Integrated support for German power grid regulations.
+Power Limiting: When the AUX 2 input is closed, the system limits battery charging to 4.2 kW. This is a default setting in current VEConfigure versions.
+==== VRM & Bug Fixes (v558) ====
+Remote Switch Fix: Resolved an issue where the Inverter/Charger control switch would disappear from the VRM Portal dashboard.
+Stability: General bug fixes and performance optimizations accumulated since v502.
+===== Upgrade Precautions =====
+^ Step ^ Action ^
+| 1 | Backup Settings: Firmware updates reset the unit to factory defaults. Save your config via VEConfigure first. |
+| 2 | ESS Users: You may need to remove the ESS Assistant, set Grid Code to "None," and then re-add the Assistant after the update. |
+| 3 | Verification: Manually re-check battery charge voltages (Absorption/Float) and current limits after restoring your settings. |
+Note: Always use the latest version of VictronConnect or VEFlash to perform the update.
+Do you need help with the specific wiring for the AUX 2 input to meet the German grid requirements, or are you ready to backup your configuration?
