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.

Choose region(s) to apply DC electrical
|Choose the inverter(s) to be used in DC electrical|
|Choose a combiner from the library. This will disappear if a string inverter is selected|
|Strings per combiner. This will disappear if a string inverter is selected|
|String size - String size used in the table in the region. This will autopopulate|
|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|

IS AC electrical equipment supported?
Not at this time
Will this show the DC electrical routing
DC electrical does not show the routing of the DC wires.
