Abstract
The invention discloses a solar battery pack. The solar battery pack consists of a plurality of solar battery units and comprises a plurality of normally open electronic switches, wherein each solar battery unit is connected in parallel with the corresponding electronic switch; each normally open electronic switch comprises at least one controllable electronic valve piece; and each electronic valve piece comprises a normally open switch element, a sensor and a control valve. The normally open switch elements can be zero-crossing intelligent electronic switches. By using the structure, the solar battery pack has the advantages that: 1, a junction box is removed, so that cost is greatly lowered; 2, in an abnormal state, the intelligent electronic switches are used, and heating and loss are avoided, so that safety is improved, and the power generating loss of a solar component is reduced; and 3, the complexity of a component is reduced, and only wiring ports are required to be matched with the component, so that the heat radiating efficiency and performance of the component are improved.
Description
Technical field
the present invention relates to a kind of solar battery group.
Background technology
The structure of
solar components use at present is shown in accompanying drawing 2; Exist unusually in case the battery component of certain diode mapping position is inner; Diode will play the bypass effect, and the solar cell of this position of mapping can't be worked in this time, and the problem of bringing like this is; If have 10% to damage, thereby other discharge capabilities that also will be bypassed the waste cell panel of 90%.
owing to the self attributes of diode, diode may produce the problem of leakage current when the cell panel operate as normal.
in addition because the traditional bypass diode internal resistance of bypass is big, in being occurred under the unusual situation of mapping by the battery of bypass; When needing big current lead-through in the diode; Diode will produce huge heat, can produce two problems like this, the thermal loss of diode; The loss of solar power generation energy simultaneously, the generating efficiency that had both reduced solar cell has also increased the possibility that diode damages.
traditional components needs the terminal box of specialized designs diode use in order to consider this problem, and the appearance of terminal box has increased the complexity of solar components, causes the decline of battery component heat dispersion and the complicacy of structure simultaneously.The inevitable like this rising that has just caused cost.
Summary of the invention
the purpose of this invention is to provide a kind of solar battery group; When unusual situation appearred in solar battery group any local, solar battery group can partly be carried out short circuit unusually and kept other non-unusual parts still can operate as normal.
For achieving the above object, the invention provides a kind of solar battery group, this solar battery group is made up of a plurality of solar battery cells, and it also comprises:
a plurality of electronic switches of often opening; Each solar battery cell all is parallel with electronic switch corresponding with it; Each is often driven electronic switch and comprises a controlled electronics valve member at least; When solar battery cell voltage was undesired, said electronics valve member action of often driving electronic switch was with its corresponding solar battery cell bypass.
preferably, the said electronic switch of often opening is the zero-based electronic switch.
Preferably, the said electronics valve member of often driving electronic switch comprises
The normal open switch element, when closed with pairing solar battery cell bypass;
Transducer has and detects solar battery cell voltage;
control valve, with sensor to data inputs and be converted into and drive normal open switch element actuating signal.
preferably, this solar battery group adopts surface mounting technology.Middle control module, control module has the multi-channel output mouth in this;
solar panel, this solar panel can charge to lithium ion battery through middle control module, also can be through middle control module to each output port output electric energy.
preferably, this solar charger adopts surface mounting technology.
The present invention adopts above structure, has the following advantages:
1. the leakage problem when having solved the cell panel operate as normal has prevented to cause owing to leakage current the decline of solar components generating efficiency;
2. forgone Problem of Failure under a large amount of switch number of times of diode;
3. remove terminal box, greatly reduced cost;
4. under the abnormality, adopt intelligent electronic switch, zero heating, zero loss has improved fail safe and has reduced the solar components generation loss;
have 5. reduced the assembly complexity, only need on the assembly to cooperate Wiring port to get final product, thereby the radiating efficiency that improves assembly have promoted assembly property.
