Description
Technical field
The present invention relates to exchange component technology field, particularly to a kind of intelligent low-pressure exchange assembly.
Background technology
Photovoltaic module now is used mostly group string inverter or Miniature inverter generates electricity by way of merging two or more grid systems.Compared to tradition
Group string inverter, Miniature inverter can provide the MPPT of component level so that assembly can run under shade and have height
Fault-tolerance, therefore can improve considerable generated energy, cuts down certain design and installation cost simultaneously, and provides independent assembly
Detection, integrated ground and increase security of system.And use the assembly of Miniature inverter, the generating of its monolithic photovoltaic module
Amount can't affect this group and go here and there the generated energy of other assemblies, has ensured the gene-ration revenue of client.But single watt of Miniature inverter one-tenth
This is much higher compared to for group string inverter,
And the shortcoming of Miniature inverter exchange assembly is: single watt relatively costly.
Additionally the shortcoming of conventional group string inverter exchange assembly is:
1, MPPT and the generated energy monitoring of component level cannot be provided；
2, a certain block assembly in group string goes wrong (damage or shadow occlusion), can affect this group and go here and there the sending out of other assemblies
Electricity situation；
3, have high-tension electricity, safeguard, installation cost higher；
Summary of the invention
For solving the problems referred to above, the invention provides a kind of intelligent low-pressure exchange assembly, both there is Miniature inverter exchange
Assembly advantage, has again the exchange kit form of the feature of conventional group string inverter exchange single watt of low cost of assembly.
In order to overcome deficiency of the prior art, the invention provides the solution of a kind of intelligent low-pressure exchange assembly,
Specific as follows:
A kind of intelligent low-pressure exchange assembly, including some exchange assemblies, described exchange assembly includes inverter, described inversion
Device directly snaps fit onto in the rosette of exchange assembly；The inverter of described exchange assembly is by the DC voltage of institute's connected components, electric current
Be converted directly into alternating voltage, the mode of electric current exports, and there is not the process boosting to line voltage；Exchange assembly with string
The mode of connection is attached；The inverter that this exchange assembly is used can regulate and control each exchange voluntarily according to the frequency of accessed electrical network
The grid-connected frequency of assembly.
The effect of the present invention is as follows:
1, the present invention is a kind of exchange kit form that can directly snapped fit onto by inverter on assembly junction box；
2, the DC voltage of institute's connected components, electric current are converted directly into alternating voltage, electric current by the inverter of this exchange assembly
Mode export, there is the process of line voltage of boosting to；
3, being attached in series of this exchange assembly, and because this inverter does not have and boosts to electrical network
The process of voltage, the exchange component count needed for the most grid-connected group of string need to select according to grid-connected voltage；
4, the inverter that this exchange assembly is used can regulate and control each exchange assembly voluntarily according to the frequency of accessed electrical network
Grid-connected frequency, therefore this exchange assembly can use in worldwide；
5, (damaging or shadow occlusion) when a block assembly of same group of string goes wrong, the remaining component of this group string can carry
Up voltage, reduces electric current, so that this group string exchange assembly can normally generate electricity by way of merging two or more grid systems.
Accompanying drawing explanation
Fig. 1 is the structural representation of exchange assembly；
Fig. 2 is the operating diagram of intelligent low-pressure exchange assembly.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described further.
As shown in Figure 1 and Figure 2, the intelligent low-pressure exchange assembly of the present invention, including some exchange assemblies 1, described exchange assembly
Including inverter 2, described inverter directly snaps fit onto in the rosette 3 of exchange assembly；The inverter of described exchange assembly is by institute
The DC voltage of connected components, electric current are converted directly into alternating voltage, the mode of electric current exports, and do not exist and boost to line voltage
Process；Being attached in series of exchange assembly；The inverter that this exchange assembly is used can be according to being accessed electricity
The frequency of net regulates and controls the grid-connected frequency of each exchange assembly voluntarily.
When a block assembly of same group of string goes wrong, the remaining component meeting booster tension of this group string, reduces electric current.
Described problem includes damaging or shadow occlusion.
Advantages of the present invention:
1, the present invention is a kind of exchange kit form that can directly snapped fit onto by inverter on assembly junction box；
2, the DC voltage of institute's connected components, electric current are converted directly into alternating voltage, electric current by the inverter of this exchange assembly
Mode export, there is the process of line voltage of boosting to；
3, being attached in series of this exchange assembly, and because this inverter does not have and boosts to electrical network
The process of voltage, the exchange component count needed for the most grid-connected group of string need to select according to grid-connected voltage；
4, the inverter that this exchange assembly is used can regulate and control each exchange assembly voluntarily according to the frequency of accessed electrical network
Grid-connected frequency, therefore this exchange assembly can use in worldwide；
5, (damaging or shadow occlusion) when a block assembly of same group of string goes wrong, the remaining component of this group string can carry
Up voltage, reduces electric current, so that the Energy Maximization of this group string.
In the way of accompanying drawing illustrates, the present invention is described above, it will be understood by those of skill in the art that the disclosure
It is not limited to embodiments described above, in the case of without departing from the scope of the present invention, can make a variety of changes, change and replace
Change.
