6.6 Measurement Precision
Any kind of measurement always depends on the accuracy. The measurements
taken by the Sunny Boy are required for its operational control and the control unit of
current to be fed to the grid. The reproducibility of measurement values is conceived
for there requirements. A maximum measurement error is conceived for an ambient
temperature
ϑ
U
of 25 °C. Other temperatures must be evaluated with respect to the
inaccuracy resulting from these different temperatures.
