Solar charge and discharge controller

The utility model provides a solar charge and discharge controller, comprising at least one touch key, a conversion circuit, and an execution circuit. Each touch key is used for outputting an electric signal upon reception of a touch action. The conversion circuit is used for converting the electric signal output by the touch key into a digital signal. The execution circuit is used for receiving the digital signal and sending a function control signal based on the received digital signal. According to the solar charge and discharge controller provided by the utility model, the touch sensitive type key is used as the controlling device so that the sealing performance of the controller is improved and the controller is enabled to have an improved severe environment resisting capability. Therefore, the life of the controller is prolonged.
