Abstract:
1. A solar energy control system comprising: a storage battery; a solar energy operated absorption board connected to the battery for charging the battery; a load connected to the battery for receiving a working voltage from the battery; a controller comprising a microprocessor and a communication interface connected to the microprocessor, wherein the microprocessor is connected to the absorption board to detect the voltage of the absorption board and judging a time for day or night to control the absorption board to charge the battery according to the detected voltage; a first ZigBee module; a second ZigBee module connected to the communication interface; and a monitoring device connected to the first ZigBee module, the monitoring device monitoring a status of the microprocessor and sending control instructions to the microprocessor through the first and second ZigBee modules and the communication interface, wherein when the voltage of the absorption board detected by the microprocessor is high, the microprocessor judges that it is daytime and controls the absorption board to charge the storage battery, and at the same time the microprocessor prevents the storage battery outputting voltage to the load; when the voltage of the absorption board detected by the microprocessor is low, the microprocessor judges that it is nighttime and controls the storage battery to provide a working voltage to the load.
