Hi Ernie,
Thanks for the reply.
I have spec'd everything out and hopefully sized the Solar Panel properly for my demand and backup needs.
I come from the electrical world so I know some about Solar Panel systems but I am still learning.

grapesolar.com has some basic level info about solar panels and calculations if you are interested, don't know if I will use them or build my own.

I was just curious if anyone has done jobs like this and maybe has a "go to" product that is catered to this need.
