Adjustable Parameters
You can change the following parameters for voltage and frequency monitoring with a communication product (e.g. Sunny Explorer) ( > Changing Operating Parameters).
The voltage specifications are based on the line-to-neutral voltages. If the set values are present as line-to-line voltages, these have to be converted to line-to-neutral voltages. |
