Abstract
The utility model discloses an alternating/direct current dual-power distribution box which comprises a distribution box. The interior of the distribution box is provided with a photovoltaic controller. The power input end of the photovoltaic controller is connected with a battery which is disposed at the exterior of the distribution box. A direct-current bus is connected to the power output end of the photovoltaic controller. The direct-current bus is connected with a direct-current connection interface which is used for supplying a direct current to a direct-current load. The direct-current bus is also connected with an alternating-current bus through a photovoltaic inverter. The alternating-current bus is connected with the commercial power and alternating-current equipment. A solar photovoltaic cell and the commercial power are employed as dual-power input, and a direct-current system, which is formed through an arranged photovoltaic controller, directly supplies uninterrupted direct-current power to a household direct-current load, thereby reducing the conversion loss of electric energy. Meanwhile, a direct current supplies uninterrupted alternating-current power for the alternating-current bus side through the photovoltaic inverter, and the uninterrupted alternating-current power is supplied to the household alternating-current load. The surplus electric quantity can be conveyed to a commercial-power public grid and supplies uninterrupted direct-current and alternating-current power for a family, thereby reducing the cost of electricity.
