Independent solar power generation controller, solar power generation system, and method

Abstract

The invention relates to an independent solar power generation controller, and the controller is used for a solar power generation system, and controls a solar power supply device to work in a state of maximum power, so as to outputs a corresponding control signal and an output voltage to a storage battery according to the state of a solar cell panel. The controller comprises a main circuit, a sampling circuit, a microprocessing control circuit, an MOS tube drive circuit, and a power circuit. The microprocessing control circuit is connected with a main circuit through the MOS tube drive circuit, and the MOS tube drive circuit comprises a backflow prevention MOS tube. When the input end voltage of the microprocessing control circuit is lower than an output end voltage, the MOS tube drive circuit is controlled to open the backflow prevention MOS tube NMOS-in for backflow prevention. When the input end voltage of the microprocessing control circuit is greater than the output end voltage, the MOS tube drive circuit is connected, and the microprocessing control circuit is enabled to control the main circuit for charging the storage battery.

Description

Technical field [0001] The present invention relates to a high-efficiency solar power generation system combined with the Internet of Things, in particular to an independent solar power generation controller that can realize high-efficiency conversion of solar energy, and can realize remote real-time monitoring and display of users during use by Internet of Things technology. Smart solar power system with daily power generation changes. Background technique [0002] The energy consumption structure dominated by coal, oil and natural gas has made environmental pollution problems increasingly serious. Coupled with the exhaustion of non-renewable energy sources, the development and utilization of green and environmentally friendly renewable energy sources and optimizing the energy structure have become the common demands of all countries and people around the world. Among the many alternative energy options, solar energy is an ideal green energy that fits the sustainable development...

Problems solved by technology

[0005] As a further improvement, most of the current solar power generation systems use face-to-face button screens for human-computer interaction, which has caused great restrictions on human actions, and it is difficult to monitor the charging situation in real time, and some power generation controllers do not even have Human-computer interaction makes it difficult for users to intuitively know the current working status; although some solar power generation systems can realize remote monitoring of charging conditions, they cannot establish a corresponding database to provide users with power generation information for a long period of time
