Abstract

The invention discloses a solar inverter power supply. A solar photovoltaic cell and a commercial power complementation unit are connected with an intelligent charging and discharge control unit respectively. The intelligent charging and discharging control unit is connected with a lead-acid battery which is connected with an inverter power supply. The commercial power complementation unit comprises a first unit, a second unit, a third unit and a fourth unit, wherein the first, second and fourth units are formed by connecting commercial power and the intelligent charging and discharging control unit through a transformer; and the third unit is formed by directly connecting the commercial power and the intelligent charging and discharging control unit. Solar energy is adopted as a power supply, so that energy sources are saved, and environmental protection is realized. The inverter power supply reaches an advanced world standard, the photoelectric conversion efficiency of the inverter power supply reaches 15 percent, and the efficiency of an inverter is also over 90 percent. The solar inverter power supply has pure waveforms, a small harmonic component, the distortion degree of less than 1 percent, high anti-overload capability, high short circuit protection capability, high efficiency, a high energy-saving index and a high environmental protection index.

Description

technical field [0001] The invention relates to an inverter power supply. In particular, it relates to a solar inverter power supply with high photoelectric conversion rate and high inverter working efficiency. Background technique [0002] Solar energy (solar Energy) generally refers to the radiant energy of sunlight.
