Hi Zane: Newbie Here, but just wanted to say " 100 FREE SOLAR panels WOW" I just recently Installed 10- 120 watt solar panels on my work shop,, with a 880 amp batterie bank storage. Before I started I knew only the basics of electricity,but through the internet I got a great education. I can now run all my lights and tools ( except the large 220v tools) on the new solar system. And did all the work myself. I would recommend an mppt charge controller, or several in your case, as this would make your life much easier. I f you want to save some money, make your own combiner boxes, and crimp your own ends on the large gauge wires and even make your own lugs.
