The energy meter is returned in 64 bits.
Query for the display of measured values in kWh in 32 bits and in Wh in 16 bits:
Important This version is for applications that cannot directly process 64 bit meters or
can only process them with difficulty. Each meter is assigned its own exponent byte. The
16 bit Wh meter can accept values between 0 and 999.

MSB
The exponent byte has the following coding:
0B
OV
OV = Overflow or invalid
UV = Underflow
Example of a 16 bit value:
MSB = 2, LSB = 100, EXP = 0
Value = 612
