Wizard - Inverter sizing

The wizard offers several ways to choose the inverters of the system depending on the settings selected in the Project settings.

• If the choice of the module is primary with respect to the inverter

The module has already been selected, if the power is defined by designer is showing the result of research into the database, the inverters are compatible with the grid of the PV system chosen. All models proposed creates a solution verified of the system. Among the proposed solutions, those with optimal utilization are represented by the color green solutions, those who exploit shortly the inverter are represented in yellow and those who exploit overly the inverter are represented in red.

If the power is defined by the layout of the system It will be possible to have an arrangement of strings of the system with different orientations and string lengths, so the program will seek the best arrangement of strings on the inverters based on the Number of inverters in the system. The distribution of strings on inverters requires that each MPPT will have a homogenous PV array for string length.

The designer should therefore individually choose each inverter of the system between those that are compatible with the photovoltaic field in input to each inverter. If the photovoltaic fields are equal to each other, it will be possible to specify the Same inverter model for each fields

Research in database can be made by searching among the favorites or by specifying an inverter manufacturer.

The double click on a row containing the model of the inverter, opens a window that displays all of the technical data of the inverter.

• If the choice of the inverter is primary with respect to the module

If you want to choose primarily the inverter, the program requires the definition of the number of inverters you want to use. The power of the system will still be equally divided on the number of inverters. The window also displays the list of inverters compatible with the request power, the search is performed within the database of inverter of the program.

Among the proposed solutions, those with optimal utilization of the inverter are shown with the green solutions, the solutions who under-uses the inverter are shown in yellow and those who exploit overly the inverter are represented in red.

The limits of sizing on power of inverter can be configured in the project properties.
