pvlib.inverter.sandia_multi(v_dc, p_dc, inverter)[source]

Convert DC power and voltage to AC power for an inverter with multiple MPPT inputs.

Uses Sandia’s Grid-Connected PV Inverter model 1.

Parameters

  • v_dc (tuple, list or array of numeric) – DC voltage on each MPPT input of the inverter. If type is array, must be 2d with axis 0 being the MPPT inputs. [V]

  • p_dc (tuple, list or array of numeric) – DC power on each MPPT input of the inverter. If type is array, must be 2d with axis 0 being the MPPT inputs. [W]

  • inverter (dict-like) – Defines parameters for the inverter model in 1.

Returns

power_ac (numeric) – AC power output for the inverter. [W]

Raises

ValueError – If v_dc and p_dc have different lengths.

Notes

See pvlib.inverter.sandia() for definition of the parameters in inverter.
