How do I create a block based around an inverter enclosure?


To learn more about block creation, visit our help article on creating a block: What is Block Creation?

  1. In the SunDAT panels, select Block Creation.  Then select the tab: Electrical Block.
  2. In the drop down menu for selecting Electrical Block type, choose the Inverter Enclosure.  The inputs for creating an inverter block will appear below.
  3. Choose "New" in the first drop-down menu and then give your new combiner block a name in the next input.
  4. Go to the Choose a table drop-down menu and select the table you want to use in the block.
  5. Go to the Choose an Inverter Enclosure and select the inverter enclosure that is based on the inverter you are using for the project.  If you do not see an inverter enclosure you want, you will need to create one in the Equipment Library.  After selecting your inverter enclosure, the Block details information will begin to populate.
  6. In the Choose a Combiner, select the combiner you want to use.  
  7. In the Strings per combiner, input the number of strings that will be going into the combiner box.
  8. Next, set up what the block will look like by specifying the number of tables in a row(tables in the north-south direction) and column(tables in the east-west direction).  
  9. Specify the spacing between tables with the North-South Gap and East-West Gap.  Note: when putting in the table spacing, it is locked in.  This means if a GCR is set to 40%, when a layout is run, the spacing has to use the same GCR.  If you want to do a PV layout run with 35% GCR, then you will need create a new block with that spacing.  So, a recommended practice is to put the spacing into the Block Name like GCR percentage.
  10. If advance spacing is needed or a skew is needed, check the Advanced block configuration and fill in the information for additional spacing and/or skew.
  11. When ready press the Create button and you will see your combiner block appear in SketchUp. 
  12. Press OK in the message box and now your combiner block is available to run PV layouts.
