Abstract

The invention discloses a voltage filtering type solar energy inverter system based on residual electric quantity detection. 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 and a voltage acquisition circuit which are respectively connected with the storage cell, a DC filtering circuit and an inverter unit which are respectively connected with the DC voltage stabilizer, and a single-chip microcomputer connected with the voltage acquisition circuit. According to the system, an output DC voltage can be processed through the DC filtering circuit, the DC voltage after processing is more stable, electric quantity of the storage cell can be detected, so the electric quantity of the storage cell can be timely known, and damage to an electric appliance because of the over-low electric quantity of the storage cell in a use process can be avoided.

Description

technical field [0001] The invention relates to an inverter system, in particular to a voltage filtering solar inverter system based on remaining power detection. 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. Co...
