New Austin Remodel sample

ChiefArchitect posted pretty cool Austin remodel plan and the layout. https://www.chiefarchitect.com/products/samples.html#projects-austin

 

After playing with it a bit, noticed an issue with "Solar diagram" and just letting them know. This diagram has many mistakes... I know it never meant to be real...

 

But in case you are interested:

- Solar panels are wired in series, and those series are wired in parallel, where VOC [voltage at open] of a panel x number of panels should not exceed max DC input on an inverter. So if your inverter max DC input voltage 240v and a [72 cel] solar panel produces 41v - You can have a max of 6 panels [or better 5] per series. Adding "up to 20" together could produce super high voltage.

- "Parallel Consolidator" can serves as [Combiner] for these parallel strings. Multiple groups let say of 6 panels output combined together. Not needed if you only have one string.

- A "Charge controller" is what charges the batteries  and Alternative Current L1 and L2 never comes anywhere near those batteries, rather only connect to the inverter.

- An inverter what produces the AC current, feed by DC  [or AC] and decides when to charge the batteries or consume thus powers a charge controller. 

- A battery bank would only get + and - from the charge controller. [may need a disconnect or a fuse]  

- An AC neutral leg is not the same as - terminal from the solar strand.

I believe it is more like this:

 

ground is earthen ground.

Or like this: a neutral (gray) never goes anywhere near DC circuits, thus DC negative (blue) was added.

Grounding should be the shortest path IMHO, also some disputes are there.

This is the diagram from a solar permit I drew recently. P.S. I am not an expert in either electricity or solar layout, but I did consult with one.
