Embodiment

[0020] Such as figure 1 As shown, the solar inverter system based on the output voltage filtering process of the present invention is mainly composed of a solar cell group, a storage battery connected to the solar cell group, a DC voltage stabilizer connected to the storage battery, and a DC voltage stabilizer connected respectively It is composed of connected DC filter circuit and inverter unit.

[0021] Wherein, the solar cell group is used to convert solar energy into electric energy, and it needs to be arranged in a place with light when in use. The storage battery is used to store the electric energy output by the solar battery. The DC voltage stabilizer can process the output voltage of the battery, and the processed voltage is more stable. It is preferably realized by using the WYJ type DC voltage stabilizer produced by Shanghai Wenhua Power Equipment Co., Ltd. The direct current filter circuit can make the waveform output by the direct current voltage stabilizer more...

Abstract

The invention discloses a solar energy inverter system based on output voltage filtering processing. The system is characterized by mainly comprising a solar energy cell pack, a storage cell connected with the solar energy cell pack, a DC voltage stabilizer connected with the storage cell, and a DC filtering circuit and an inverter unit which are respectively connected with the DC voltage stabilizer, wherein the DC filtering circuit comprises a triode VT4, a triode VT5 and an amplifier P1. The system employs solar energy for power generation, solar energy resources do not dry up, and the solar energy resources are widely distributed, are green and environmental friendly and are suitable for wide popularization. According to the system, an output DC voltage can be processed through the DC filtering circuit, and the DC voltage after processing is more stable.

Description

technical field [0001] The invention relates to an inverter system, in particular to a solar inverter system based on output voltage filtering processing. Background technique [0002] At present, household electricity is generally supplied by the grid. However, in some areas where the grid is not erected or there are frequent power outages, there are great difficulties in domestic electricity consumption. With the development of inverter technology, it has become possible to use batteries to provide domestic electricity, especially in some areas with sufficient sunshine, using solar charging technology to convert solar energy into electrical energy and store it in the battery, and then convert the DC output of the battery when using electricity The AC power is used for household use, thereby solving the defect that the grid cannot be used for power supply. However, the conversion efficiency of existing inverter systems is too low to meet people's living needs. Contents o...
