Problems solved by technology

[0002] Most of the existing photovoltaic energy conversion uses the cooperation of solar panels and power storage equipment to convert light energy into solar energy. Many devices on the board are complex and prone to abnormal changes in voltage and temperature, which will affect the conversion of electric energy, and if it takes a long time, it will reduce the service life of the equipment and even cause a fire
[0003] Most of the existing manual inspection and voltage display are used to observe photovoltaic equipment, which is not only time-consuming and labor-intensive, but also easy to miss. Photovoltaic power generation is often located in places with relatively long sunshine hours and relatively high temperatures, which can easily cause over-temperature and over-voltage phenomena. Some cannot intelligently and scientifically monitor the temperature and voltage parameters of photovoltaic equipment from time to time

Abstract

The invention provides an on-line monitoring system used for photovoltaic power generation. The system comprises an electric power reservoir integratedly connected to a solar panel. The electric power reservoir comprises an electric energy converter and a current condenser connected to the electric energy converter. The electric energy converter is connected to a voltage detection unit. The current condenser is connected to a temperature detection unit. Compared to the prior art, by using the system of the invention, a voltage and a temperature of the electric power reservoir can be constantly monitored so that a work parameter is in a monitoring scope and an adverse phenomenon caused by an excessive parameter is effectively prevented. From remote control and wireless transmission, collected data can be fed back to operation personnel of a control terminal in a second so that real-time monitoring can be reached, an abnormity can be discovered timely and measures can be adopted timely.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic industry equipment, and relates to an online monitoring system for photovoltaic power generation. Background technique [0002] Most of the existing photovoltaic energy conversion uses the cooperation of solar panels and power storage equipment to convert light energy into solar energy. The high complexity of many devices on the board is prone to abnormal changes in voltage and temperature, which will affect the conversion of electric energy in the slightest, and will reduce the service life of the equipment over time, and even cause fires. [0003] Most of the existing manual inspection and voltage display are used to observe photovoltaic equipment, which is not only time-consuming and labor-intensive, but also easy to miss. Photovoltaic power generation is often located in places with relatively long sunshine hours and relatively high temperatures, which can easily cause over-temperature an...
