3 Introduction
Each SOLPLUS inverter features a number of interfaces and communication ports via which the data
of the inverter can be read out. A total of approximately 300 inverter parameters can be read out.
The data provided by the inverter are divided into the following categories:
1 Yield and display values: These values represent the instantaneous values of the inverter.
They are actual values and display values that cannot be altered.
2 Setting values: These are values that can be set and altered individually. Depending on the
importance and meaning of the parameters, these values can be set by the final customer, the
fitter or the utility company. For security purposes, different password levels are incorporated.
