The inverter parameter database provided below is a combination of performance parameters from manufacturers’ specification sheets and experimental data measured at recognized testing laboratories, including field tests at Sandia. In each row, the source for the parameters displayed was provided, in some cases resulting in multiple entries for the same inverter type. Additional parameters of use to PV system designers, but not explicitly used in our performance model, were also included in the database. Vdcmax and Idcmax are the upper limits for dc voltage and current as defined by the manufacturer. MPPT-Low and MPPT-High define the lower and upper voltage limits within which the inverter tracks the maximum-power point of the PV array. Acceptable ambient temperature extremes and the weight of the inverter are also provided.
The parameters were used for validation of Sandia’s model for grid-connected photovoltaic inverters.
