Very interesting real-time and general info can be seen via the mobile app connected to our PV inverter.
The current value of the grid voltage is 235.9 V
The national standard here is 230 V but in our house it is always above the standard, sometimes even hitting 242 V, and that unfortunately is within the allowed deviation of +-10%.
The grid frequency is also a bit higher, also within the allowed deviation.
Sliding on the chart on the bottom of the app screen allows to see the hour of the beginning of the yield.
