Anyone aware of something like this? Just talking in terms of perhaps choosing the main components and it would output the results in terms of uptime under certain load, etc.

Perhaps even a bill of materials of common parts that need to be installed along with the main ones. 

Thank you

Also looking from Software that one can use to draw a schematic or similar. Anyone ? It does not have to be software specific for renewable energy, just to draw the electrical circuit showing the grid side, switches, flow of the live and neutral cable, fuses etc.  

Morne look at ProfiCAD or Visio

For a professional level of software have a look at www.accasoftware.com 

Lots of very interesting videos on Youtube.

I get what the OP is looking for and I have never found anything that is geared towards PV systems.

Ideally you want something that has a list if Inverters, Batteries, Panels and Electrical boxes that you can place on a sheet and then connect the wiring.  At this point I have found it's easier to just use Photoshop and use device drawings that are on the Net and then set up Multiple layers in Photoshop.   DC wiring and AC wiring Layers will make removing one set of wiring to examine another set much easier.
