The AllEarth Gen 4 Solar Tracker, the latest addition to the AllEarth dual-axis tracker family, uses GPS and wireless technology to follow the sun throughout the day, producing up to 45% more energy than fixed systems. Gen 4 key features include an electrically powered motor with a sleek design and incomparable efficiency. The Computer Control system is updated with new power monitoring features, allowing power generation and mode status to be checked with ease. Gen 4 is a self-powered, grid-tied system which allows it to keep following the sun even when the grid is down, because the tracker draws energy from the panels and stores it in a small battery.
