MPPT or DC-DC converter

In PVsyst, the MPPT or DC-DC converter device - if present - is considered as part of the Regulator.

Its operation and parameters are quite similar to the Inverter ones (in fact, the inverter is a MPPT-AC converter), i.e:

  • DC-DC converter: Nominal Fixed Input voltage,
  • MPPT converter: Minimum and maximum MPP tracking voltages,
  • Both : Absolute maximum input voltage,
  • Power threshold,
  • Efficiency profile according to power,
  • Maximum and eventually European efficiency,
  • Behavior type at power overload or outside the voltage window.

As for inverter, the simulation process accumulates detailed specific energy losses during operating (inefficiency, under threshold, power overload, outside voltage requirements, etc).
