I have been reading/watching a lot of positive reviews of the Titan generator, and am wondering if any of you smart solar engineers have ever spec'd/priced out a custom built system the closely matches the Titan's capabilities? I just thought with all the high quality solar system components and batteries, that someone may have done this to see if they could build something similar or even better that the Titan for similar or less money. I would be interested and thankful for any information or suggestions on a custom build before I drop the money on a Titan which in itself fulfills most of my needs.
