This automatic dual-axis solar tracker controller uses a high-precision sensor to detect sunlight direction. A microcontroller processes the signal and controls relay assemblies to drive the platform motors, completing the sun tracking process. Features include a high-wind leveling function (requires optional air speed sensor) and automatic reset on cloudy days or at night. An English LCD displays parameters, which can be set using the onboard keys or the included infrared remote. This controller is designed for use with a two-degree-of-freedom platform. Compatible platform motors are 12V or 24V DC brush motors, with a current draw per motor of less than 15A (each axis is pre-configured with a 10A fuse). Limit switches are required on all four directions of platform movement. Material: Plastic Color: White and Black Package Contents: 1 x Main Controller, 1 x Remote Control, 1 x Wind Speed Sensor
