Steady red light means you are charging the battery with non-solar energy - eg the plug charger we provided with the starter kit.
If you have the solar panel connected you should hold a piece of paper or your hand briefly in front of the solar panel. The solar battery will then calibrate itself and the 'red eye' will disappear. The Changers solar battery distinguishes between renewable solar power from the panel and conventional power from the grid. When you are charging with power from the grid the ring flashes red.
