6.4.4 Precision of Measured Value Acquisition
Acquisition of measured values always is imprecise within a certain margin. The
measued values acquired by the Sunny Boy 4200TL Multi-String are required for its
system management and control of current to be fed to the grid. This is why measured
values of the Sunny Boy 4200TL Multi-String must be reproducible. The maximum er-
ror 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.
