Energy is made available in hundreds of watt-hours (var-hours) in double
16-bit register, and for this reason, one must divide them by 10 when
calculating values of particular energy from registers, ie:
Imported active energy = (register 4038 value x 65536 + register 4039 value) /10 [kWh]
Exported active energy = (register 4040 value x 65536 + register 4041 value) /10 [kWh]
Reactive inductive energy = (register 4042 value x 65536 + register 4043 value) /10 [kVarh]
Reactive capacitive energy = (register 4044 value x 65536 + register 4045 value) /10 [kVarh]
Apparent energy = (register 4046 value x 65536 + register 4047 value)/ 10 [kVAh]
Device status register (address 4050, R):
Bit 15 – „1” – damage of the non-
volatile memory Bit 7 – „1” – the interval of averaged
power is not elapsed
Bit 14 – „1” – lack of calibration or
erroneous calibration Bit 6 – „1” – frequency for THD
calculation beyond intervals
- 48 – 52 for frequency 50 Hz,
- 58 – 62 for frequency 60 Hz
Bit 13 – „1” – error of parameter
values Bit 5 – „1” – voltage too low for
frequency measurements
Bit 12 – „1” – error of energy values Bit 4 – „1” – too low voltage of phase L3
Bit 11 – „1” – error of phase
sequence Bit 3 – „1” – too low voltage of phase L2
Bit 10 – current range „0” – 1 A~;
1” – 5 A~ Bit 2 – „1” – too low voltage of phase L1
Bit 9 Bit 8 Voltage range Bit 1 – reserved
0 0 57.7 V~
0 1 230 V~ Bit 0 – state of relay output „1” – On,
„0” - off
