Abstract:

 One kind of solar energy power intelligent controller is designed in this paper， which uses a low-power single-chip microcomputer P87LPC767 as its control circuit core， low pressure sodium lamp（LPS） as its load. Under the control of P87LPC767， the direct current power converted from the photovoltaic array was stored effectively and used reasonably， possessing effects on both energy saving and environmental protection. The system can realize these functions， such as auto-control course of charge and discharge， open and short protected， over-current protected， over-voltage protected of the load， anti-reverse protected， over charge or discharge of battery protected， and it indications for the photovoltaic charging， battery status， load breakdown or various faults coming out. Finally， the experiments show that this intelligent controller system’s performance is stable.
