MPPT or DC-DC converter

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

Its operation and parameters are similar to those of the inverter (in fact, the inverter is an MPPT-AC converter):

  • 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 European efficiency.
  • Behavior type at power overload or outside the voltage window.

Like the inverter, the simulation process accumulates detailed specific energy losses during operation (inefficiency, under-threshold operation, power overload, outside voltage requirements, etc.).
