Congratulations on a clean install. You'll love the panel output and how easy it makes keeping the batteries up. Of course you'll now have to go over the rig and minimize use. Things like phantom loads, LED's, and keeping close watch on your standard use and way of living. We also have about 560W of panels, a Morningstar MPPT controller, and plenty of wire size to reduce line losses. We find we can actually also run a 1 meter Hughes Net Internet dish and a few hours of TV use without having to run the generator.
Again, a great design and install. Best of luck with it.
