The temperature zone subdivision control alternating current and direct current electric water heater uses photovoltaic electric energy as much as possible to reduce the use of city power. The temperature zone subdivision control alternating current and direct current electric water heater comprises a direct current power supply circuit, an alternating current power supply circuit, a temperature sensor and a controller. The direct current power supply circuit and the alternating current power supply circuit both are connected with the electric water heater and used for supplying power source to the electric water heater. The temperature sensor which is arranged in the electric water heater and connected with an input end of the controller is used for detecting the water temperature in the electric water heater and converting a temperature signal to an electrical signal to input to the controller. Controlling ends of the controller are connected with the direct current power supply circuit and the alternating current power supply circuit, and according to the electrical signal sent by the temperature sensor, the controller controls the direct current power supply circuit and the alternating current power supply circuit to independently work in two respective preset ranges of threshold.
