AcuRev 1310 Modbus Map · version 1.00
AcuRev 1310 DIN-Rail Power Meter Users Manual · version 1.2.11, 2026-10

AcuRev 1312 (single phase), 1313 (three phase) and 1314 (three phase with neutral CT). Accuenergy publishes this manual as the AcuRev 1300 manual too; the SunSpec block from 0x1045 carries the AcuRev 1300 register names.
FC03 reads, FC10 writes; values are big endian, high word first. Floats are IEEE 754.
Real-time powers and demands are in kW, kvar and kVA; energies are counts of 0.01 kWh (kvarh, kVAh).
Writing energies, resets and most settings needs the communication revise authority (0x20A) after the password (0x20B).
Date/time stamps of peaks, max/min values and records (3 registers, YY MM DD hh mm ss), the TOU program, alarm settings and event logs are in the manual and not in this map.
The SunSpec common and meter models are also published from 0x1000 and from 50000; see the SunSpec maps for their layout.
