A versatile microprocessor based controller for solar tracking
A microprocessor-based solar tracking controller was designed and fabricated. In addition to
tracking, the controller is capable of acquiring photovoltaic and meteorological data from a
photovoltaic system and controlling battery/load. These features are extremely useful in
autonomous PV power systems installed in remote areas for system control and monitoring.
Solar tracking can be achieved in closed-loop and open-loop modes, and the controller can
provide either six PWM (pulse-width-modulated) signals for a three-phase, 50 Hz AC motor …
