Description
Technical field
The utility model is related to field of photovoltaic technology, more particularly to a kind of solar photovoltaic inverter.
Background technology
Photovoltaic generating system is the electricity generation system that electric energy is directly converted solar energy into using solar cell, is characterized in
Reliability height, service life length, free from environmental pollution, energy Independent Power Generation can be incorporated into the power networks again.
The critical piece of photovoltaic generating system includes solar cell array, batteries, charging-discharging controller, inversion
Device.In the case where there is light conditions, solar cell array absorbs luminous energy, and converts light energy into electric energy；Batteries store the sun
The electric energy of energy battery array conversion；Charging-discharging controller can prevent the overcharge or overdischarge of batteries；Inverter is responsible for
By converting direct-current power into alternating-current power, alternating current be able to can also be connected to the grid with independently-powered.
At present, existing photovoltaic combining inverter is generally low power device, the direct current for output that photovoltaic is confluxed
DC/AC conversion is carried out through overcurrent vreaker after stream filtering, then is connected to the grid by AC circuit breaker after carrying out ac filter, so
Grid-connected current harmonics amount is big, and poor reliability has a strong impact on the power network quality of power supply.
Utility model content
A kind of solar photovoltaic interconnected inverter of confession provided for the drawbacks described above of prior art, the utility model, its
Not only increase energy conversion efficiency, and stable and reliable operation.
In order to achieve the above object, the utility model provides following technical scheme：
A kind of solar photovoltaic inverter, it is characterised in that including：Cabinet, boost module and inversion module, direct current protecting
Device and harmonics device, the boost module and the inversion module are inside cabinet, the boost module and the inversion
Module is equipped with fin, and the direct current protecting device is arranged on the DC side of inversion module, and the harmonics device is arranged on inverse
Become the AC of module.
Wherein, it is additionally provided with thermovent on the cabinet both sides, the thermovent causes gas to enter the cabinet and successively
By the fin.
Wherein, the thermovent is symmetrical arranged.
The beneficial effects of the utility model are：A kind of photovoltaic that the utility model that the utility model is provided is provided
Inverter, substantially increases the heat dissipation capacity of fin, improves the overall transformation efficiency of photovoltaic generation, has increased and decreased photovoltaic generation system
The overall generated energy of system.
