AEG SolarCube Pro Modbus registers (AS-BBL08 / HYXi HALO): what works and what only stores

The AEG SolarCube Pro (AS-BBL08) has an RS485 port that speaks Modbus, locally and without an account, but we found no register document that matches this unit. This is the register map we built ourselves and checked register by register against the unit: how to connect, which registers work, how to control charge and discharge, which registers store a value and do nothing, and which block you never write. The whole map is also available as a CSV download.
