Abstract
The utility model relates to the technical field of junction boxes of solar battery assemblies, in particular to an intelligent junction box with three-path input. The intelligent junction box comprises a junction box, a bypass diode module is arranged in the junction box, three bypass diodes of three-path output of a protective assembly are arranged in the bypass diode module, the output of each path is connected with one bypass diode, a power optimizer with a three-path input end is arranged in the junction box, and the output of each path is connected with the power optimizer through the bypass diode. In the intelligent junction box, the current power optimizer with two-path input is changed into the one with three-path input, the current conventional solar battery assembly with only two-path output is also changed into the one with three-path output, and the inputs of three paths pass through the three bypass diodes respectively, so the intelligent junction box can reduce generating power loss caused by shadow shading and mismatched electrical performance of the solar battery assemblies; and the power optimizer can promote and control the generating power of each path of the solar battery assembly more delicately and accurately.
Description
Technical field
The utility model relates to the terminal box technical field of solar module.
Background technology
Because single solar module power output often is not enough to provide the power of actual demand, so they constitute solar cell array in the mode of series, parallel usually and meet design requirement.When choosing the solar module forming array, usually all can run into the power output that causes owing to the electrical parameter of each assembly of series and parallel is inconsistent behind the series and parallel less than single component power output sum, be referred to as mismatch loss.Simultaneously, when coupled in series,, can cause array to be operated in a certain state following time if electric current does not match, individual component is in reverse bias in the array, forms " hot spot ", does not match as if voltage when parallel connection, can cause array to be operated in a certain state following time, form in the array " circulation "." hot spot " and " circulation " all can make the individual component in the series and parallel connection be in the state of consumed power, and may undermine assembly life-span.The special solar cell array of working as can't be operated under the uniform illumination, and the mismatch loss of generation is just bigger.For the power of alleviating this moment descends, give bypass diode of a battery strings reverse parallel connection in each assembly or the assembly usually, stop an assembly or battery strings branch road to consume the electric energy of whole array.
Conventional terminal box, the electric current that solar module is produced comes together in the terminal box, and concentrated AC inverter or the direct-flow electricity utilization apparatus of outputing to, and three bypass diodes that conventional terminal box is equipped with are used to protect three string operating circuits of assembly.The power optimization device, promptly DC-DC power optimization utensil has and reduces solar module and block or do not match the generated output loss under the situation of electrical component performance at shade, and low current is converted into high electric current, further reduces the effect of the power loss of electricity generation system.
At present, existing company is used for solar photovoltaic generation system with conventional terminal box and power optimization device, its mounting means is directly to connect the power optimization device after conventional terminal box, but this mode is not combined as a whole the two, and its cost too high, do not have convenient, flexible property or the like.
The utility model content
Technical problem to be solved in the utility model is: need a kind of novel intelligent terminal box of exploitation, can optimize battery component more accurately, improve power generation performance.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of have three the tunnel and import intelligent terminal box; comprise terminal box; in terminal box, has the bypass diode module; have three bypass diodes of protection assembly three tunnel outputs in the bypass diode module; the output of every road connects a bypass diode; power optimization device with three road inputs is set in terminal box, and the output of every road connects the power optimization device by the bypass diode.
Also have the line of remittance Wiring module in the terminal box, the line Wiring module that converges is connected with the bypass diode module.
The beneficial effects of the utility model are: this intelligent terminal box, to have only two-way input power optimizer to change at present and have three tunnel inputs, and have only the solar module of two-way output also to change three the tunnel into present routine and export, three tunnel inputs are respectively through three bypass diodes, this intelligent terminal box can not only be reduced because shade blocks the generated output loss that does not match and cause with the solar module electrical property, and the power optimization device can promote and control each road generated output of solar module more careful, accurately.
