Going to be a very simple setup, most likely two of my three panels, and MPPT charge controller and a nice deep cycle lead acid battery. The system only needs to run a few hundred watts of 12V DC hardware (lights and water pumps) so a simple charge controller + battery + panels setup should work. If I am able to get more panels and increase the size of the array I will reevaluate keeping the system off the grid and may opt for a grid tie in.
