Solar uninterrupted power system based on serial peripheral interface (SPI)

Abstract

A solar uninterrupted power system based on a serial peripheral interface (SPI) relates to the technical field of new energy control and application. A circuit of the solar uninterrupted power system comprises a solar controller, a conversion switch circuit, a voltage stabilization, contravariant and a charging integrator, wherein the solar controller is connected with a maximum power point tracking (MPPT) main control chip, the conversion switch circuit and the voltages stabilization, contravariant and the charging integrator are both connected with an inverter main control chip, and the MPPT main control chip and the inverter main control chip are effectively combined through SPI communication to achieve the purpose of intelligent and integrated management. The system removes connection of internal equipment, the MPPT main control chip and the inverter main control chip can work independently without interference to enter self preset communication fault modes when the SPI communication is in fault, and the novel solar uninterrupted power system which is safe, energy-saving and green is supplied for users.

Description

technical field [0001] This application relates to the technical field of new energy control and application, in particular to an SPI-based solar uninterruptible power supply system. Background technique [0002] With the increasing shortage of traditional energy sources, such as oil, coal, natural gas and other resources, it is impossible for human beings to start a new large-scale war for plundering energy. Then the development of new energy application technology has become an urgent need for scientific and technological personnel in various countries, and solar energy is an important part of new energy. In addition, various important equipment, such as personal computers, servers, finance, stock exchanges and other important places, have required safety requirements for power consumption, making the demand for UPS (uninterruptible power supply) and EPS (emergency power supply) also develop rapidly, but UPS (Uninterruptible Power Supply) or EPS (Emergency Power Supply) ...

AI Technical Summary

Problems solved by technology

The system mainly realizes the detection and monitoring of the system through the power regulation manager 6. When the power regulation manager 6 is damaged, the system will be in an unmanaged state, which will lead to a series of problems, such as interruption of power supply, new energy unreasonable use of

[0004] In addition, in the prior art, the integrated multi-channel power supply system requires internal connection of hardware, and generally requires manual operation to ensure uninterrupted power supply of electrical equipment and maximize the use of solar power.
