7.4.4 Precision of Measured Value Acquisition
Acquisition of measured values is always more or less imprecise. The measued values
acquired by the Sunny Boy 3300TL are required for its system management and con-
trol of current to be fed into the grid. This is why measured values of the Sunny Boy
3300TL must be reproducible. The maximum error of measured value acquisition is
specified for an ambient temperature T
U
of 25°C. A temperature coefficient failure
must be accounted for with other ambient temperatures.
