New Construction Sol-Ark 15K

I have been busy with the house, but the solar project is moving along. Sol Ark is installed next to the two panels. The non Sol ark panel is mostly 220, non essential...dryer, oven etc. The main panel runs 90% of the house. 320 amp service. From a good suggestion here, I added a transfer switch that takes the Sol Ark out of the loop and the main panel goes straight to grid. If the Sol Ark goes down or has a software issue and my wife is home alone, push the transfer and go straight to grid, work on the inverter issues later. A couple of pictures.


Pretty excited, Duke comes out next week to inspect and then we have power to the house. Ordering panels next week, doing an install on the standing seam roof.

Nice! That looks great.
 
I have been looking at the signature solar 455 watt solarever panels, but several people have suggested looking at San Tan Solar. They have unused JA solar 405W panels for $162 that are kind of intriguing. I will start with 12-14 on the roof. Anybody use these panels? Signature Solar has some nice metal roof clamps that should work very well. Ground mount will eventually go in the back yard. I will always fight some shading from trees, but it is the nature of my property.

New construction - don't you need arc fault breakers?

When I was doing residential, Indiana did not require arc fault breakers. Its been a few years I wonder if it is required now? I think we are still on 2008 NEC.

Great looking system! You've designed something very similar to what I'm planning for a new house later this year, in Maine. The idea of bypassing the inverter to go straight to grid if necessary is exactly what I have in mind. Would you mind posting the brand and model of transfer switch you used? Thanks!

It looks like a fancy, expensive, stainless steel transfer switch-whatever brand it is.

I installed a transfer switch with my install for much the same reason as OP, but I used a GE version $635 from Home Depot https://www.homedepot.com/p/GE-200-...ency-Power-Transfer-Switch-TC10324R/100150463
