String results


  • Vmp min: Vmp at minimum cells temperature
  • Vmp max: Vmp at maximum cells temperature
  • Voc min: Voc at minimum cells temperature
  • Voc max: Voc at maximum cells temperature
  • Imp: Imp input to MPPT
  • Isc: Isc input to MPPT

Checks

Comparing strings results to inverter specification:

  • ⚠️ Vmp min > Vmppt min
  • ⚠️ Vmp max < Vmppt max
  • ⚠️ Vmppt ≈ Inverter rated voltage
  • ⛔ Voc min > Vstart
  • ⛔ Voc max < Vmax DC
  • ⚠️ Imp < Imp MPPT
  • ⛔ Isc < Isc MPPT
