  • Modbus RTU over RS485, FC03 (and FC04 for input registers) reads, FC16 writes; big endian.
  • Powers and energies change scale with CT×VT: powers are 0.01 W (var, VA) below 5000 and 1 W from 5000; energies count 10 Wh up to 1000000 Wh depending on CT×VT (document notes 1 and 2).
  • Signs of the per-phase powers are separate registers (0 positive, 1 negative).
  • Changing settings: write 0x5AA5 to 0x2700, write the settings, write 0x5AA5 to 0x2700 again and 0x000A to 0x2600 to save; 0x000B to 0x2800 restores the defaults.
