Default First figures

Here are a few figures, noted this after noon (second day) during very cloudy weather :
  • Power out : 122 W
  • Total production : 1.719 kWh
  • Day production : 1148 Wh
  • Network tension : 233 V
  • Network current : 0.88 A
  • Network frequency : 49.98 Hz
  • Network impedance : 0.3 Ohm
  • PV Tension : #1 212 V / #2 197 V
  • PV Current : #1 0.4 A / #2 0.3 A
Maximum values :
  • Out AC : 677 W - 3.394 A - 238 V
  • Entry 1 : 421 W - 1.835 A - 279 V
  • Entry 2 : 396 W - 1.877 A - 260 V
I have 25 panels. One of inverter's entry has a string of 12 and the other a string of 13. Each entry has an independent tracker, maximizing current production from PV.

Next, the daily/monthly/yearly productions...
