String configuration assistant (-SX model)
The -SX inverter model measures each individual string current. When the function
operates, it detects reverse string currents, blown fuses and current deviations in the
measured strings. The standard and -S models can detect a reverse total input
current.
In the -SX model, string monitoring measures the current in each string and
compares it to the average current of selected strings. The feature generates a
warning when the current in one of the strings deviates from the average. You can set
the threshold value with the string configuration assistant. You can use this feature to
give a message of strings with low performance to the PV plant operator. The string
monitoring function is not enabled by default.
