Energy Meter energy calculation from power
(OP)
I have interfaced a smart energy meter IC (ADE7878) to a microcontroller. The datasheet of the IC can be found here, http://www.analog.com/media/en/techn..._7868_7878..... As per the datasheet, on page 50 total active power of each phase can be read from the registers AWATTHR, BWATTHR, and CWATTHR. My question is what parameters I should consider and formula I should use to calculate the kwh value ?

computed when the ADC inputs are at full scale. So will dividing the value obtained from the register by Pmax give me the actual wh value ?

I assume that your computer handles 64 bit unsigned, in that case there is ample room for the summation.
