8.9.9 Automatic String Performance Monitoring
Together with the StringMaster Pro, the CS inverter can
autonomously monitor the performance of each string
and compare it to the rest of the plant. If one string
underperforms (for example, because of dust deposits or
connector failures) compared to the others in that input,
the inverter will issue a warning on the home screen and
on both communications buses.
The performance warning is issued when:
1. The current of the failing string deviates more than [D]%
from the best performing string, AND
2. The current of the failing string is [T] Ampere less than
the best performing string, AND condition 1. and 2. are
true for at least [A] minutes.
[D] = String Deviation (Range: 0 – 100%)
[T] = String Threshold (Range: 0,5 – 30A)
[A] = Alarm Delay (Range: 0 – 1440 min)
Figure 8-27 shows the Performance Monitoring function
graphically.
