Abstract

The invention discloses a double-voltage output photovoltaic junction box. The double-voltage output photovoltaic junction box comprises a junction box body and a junction box cover arranged at the top of the junction box body, an output line is arranged on one side of the junction box body, a solar assembly leading-out line inlet connected with a solar battery pack is formed in the bottom of the junction box body, a voltage selection pulling switch is arranged on the junction box cover, and a first binding post, a second binding post, a third binding post, a fourth binding post, a positive pole power output hole post and a negative pole power output hole post are arranged in the junction box body. The first binding post is connected with the negative pole power output hole post through a metallic conduction strip, and the fourth binding post is connected with the positive pole power output hole post through a counter-charging-preventing diode. An isolation voltage switching plate is arranged between the second binding post and the third binding post in a sliding mode and electrically connected with the voltage selection pulling switch. The double-voltage output photovoltaic junction box has the advantages that two voltages can be selectively output, the structure is simple, and use is convenient.

Description

technical field [0001] The invention relates to a solar photovoltaic component power output device, in particular to a dual-voltage output photovoltaic junction box. Background technique [0002] With the progress of society, more and more people choose to travel close to nature, such as outdoor tourism and camping. In outdoor camping, the most troublesome thing is the power problem. Since modern life is inseparable from various computers, mobile phones and other mobile terminals, once the equipment is out of power, it will bring great inconvenience to the journey and make the journey lacking. fun, or sometimes need help, and the device is dead and there is no way to contact the outside world. Therefore, it will become very important to equip convenient and reliable power supply equipment on the way of camping. Solar photovoltaic power generation is loved by more and more camping enthusiasts because of its safety, reliability, portability, and ability to generate electrici...
