- Read with FC03; 32-bit values are most significant word first.
- Energies at 0x1700 are split into a low part in Wh and a high part in MWh; the signed powers at 0x1720 are always W/var.
- Not in this map: the legacy energy block at 0x1500 (kept for old Nemo 96HD software) and the setup parameters (0x2000 onwards).
