If you are in possession of hourly measured data of an operating system, with the Inverter Output energy as well as the Array Energy parameters (measured with good accuracy) , this tool allows to compare the Inverter efficiency defined for your device, with the experimental data.

Moreover you can adjust your Inverter Device Specifications in two ways:

- either by performing an automatic best fit on the data,

- or by dragging the reference points with the mouse in order to "visually" obtain the desired characteristics.

You are advised to save the inverter data with another name for your specific measured project,  and you will then be able to use it when performing the comparison simulations.
