- 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. Extension of 1 to inverters with multiple, unbalanced inputs as described in 2.
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.
power_ac (numeric) – AC power output for the inverter. [W]
ValueError – If v_dc and p_dc have different lengths.
pvlib.inverter.sandia()for definition of the parameters in inverter.
