Applicable to SunDAT Pro


Overview

Prerequisite: Region(s) with completed layouts.

In order to start with DC electrical, a Design Hierarchy has to be created.  A Design Hierarchy is the configuration fo the  electrical equipment starting with the region and going all the way to the string.  This article will explain how to generate a Design Hierarchy by first setting the parameters and inputs, followed by computing potential configurations, and then generate the select configuration as a Design Hierarchy.

Description
1

Choose region(s) to apply DC electrical

2
Choose the inverter(s) to be used in DC electrical
3
Choose a combiner from the library.  This will disappear if a string inverter is selected
4
Strings per combiner.  This will disappear if a string inverter is selected
5
String size - String size used in the table in the region.  This will autopopulate
6
Max DC/AC Ratio
7
Use Inverter Max DC as Limit toggle
8
Use Full Combiners toggle.  This will disappear if a string inverter is selected
9
Compute button - creates different combinations of the number of inverters needed for the region(s) based on inputs above.  A new window, Inverter Combinations, will open where you will choose your configuration.  
10
Selected combination - The selected combination after the combination has been selected from Inverter Combinations will appear here.  Once a selected combination is in this box, you can generate a Design Hierarchy.
11
Generate button - generates a design hierarchy based on the selected combination.  After clicking, you will be taken to Design Hierarchy
12
Reset button - clears all the inputs
