1. 
   I've revised the macro "Inverter Sizing Information.lk" to make system sizing easier.

   Directory: APP\2015.1.30\runtime\macros\Flat Plate PV

How to use:

1. 
   Download and replace the original "Inverter Sizing Information.lk"
2. 
   In a Photovoltaic (detailed) system, after you've chose the "Location and Resource", "Module" and "Inverter". Now in the "System Design" Page, click "Macros" in the lower left corner, then "Inverter Sizing Information", then "Run macro".

Have a try, appreciate your feedback/suggestion.

1. The default settings are 9 modules per string and 2 strings in parallel.
At this moment, the revised macro can help you judge whether the default settings are appropriate (most of the time, it's not...). And provide the allowable range of the modules per string/strings per inverter. Then you need to change them by hand.
2. Now I'm going to improve this, this macro should change the settings (modules per string/strings per inverter) automatically for you.
3. Will share with you guys once I'm done.
