5.4.2 Maximum daily demand
EGO700 provides the function of the maximum amount needed, can record the
most value of the amount needed on that day, can obtain through communication.
Once the time crosses the day, the maximum daily demand of the previous day will be
cleared 0.
5.4.3 Maximum monthly demand
EGO700 provides month maximum demand function, can record the demand of
that month the most value, can obtain through communication. Once the time crosses
the month, the maximum monthly demand of the last month will be cleared 0.
5.5 Electric energy
The active and reactive input and output power of EGO700 can accumulate up to
99999999.9kWh, and display one decimal place. When the accumulation reaches the
highest value, it will automatically flip.
5.6 History of electricity energy
EGO700 provides the historical electric energy of the latest 31 days, the
historical electric energy of the last 12 months and the historical electric energy of the
latest 10 years. The data saved is the total active electric energy.
5.7 Harmonic
EGO700 can measure the complete 63 times voltage and current harmonics and
their total harmonic content THD, total even harmonic content TEHD and total odd
harmonic TOHD. The harmonic data is given according to the percentage data of the
fundamental wave, with a decimal number, that is, the value of the fundamental wave
is fixed as 1000, which means it accounts for 100.0% of the effective value of the
fundamental wave, and the rest!
Total harmonic content THD refers to the sum of the higher harmonics except the
fundamental wave,press the following formula to calculate

i
indicates the harmonic order
i
X
indicates the percentage of the effective value of each harmonic
to the effective value of the fundamental wave
n
indicates the highest harmonic order, here should be 63
