In this Solar Gate Opener Installation features our heavy duty single swing gate opener kit along with the keypad, electric gate lock and solar upgrade kit. The solar upgrade kit consists of extra batteries and solar panel to give the automatic gate opener more power and better longevity without the sun. With a keypad the solar gate automation will last for approx 3-5 days with average usage, but with the solar upgrade kit this is extended to approx 7-10 days. The solar gate opener is compatible with a locking device as seen in the photo. This Lock is fully automatic with the electric gate opener. It also comes with a manual release key for ease of access for maintenance. This solar electric gate opener is completely stand alone requiring no external power to operate!
