Problems solved by technology
These photovoltaic module arrays will have problems (open circuit or short circuit) in a certain row or a certain photovoltaic module in a certain row due to installation reasons, especially after a period of use, especially large-scale photovoltaic power stations. Even hundreds of thousands of photovoltaic modules (several megawatts to tens of megawatts) are composed. If each of these multiple photovoltaic modules is monitored, the circuit is too complicated and the monitoring cost is high. If no monitoring is performed at all, even a few or even You don’t even know that hundreds of photovoltaic modules are not working, which will affect the efficiency of power generation

The invention discloses a photovoltaic module array monitor display, which comprises a photovoltaic module array, a single chip microcomputer, comparators, diodes, light emitting diodes, transistors and resistors. The photovoltaic module array is formed by a plurality of rows of photovoltaic module integrated modules, therefore, the voltage of each row of photovoltaic module integrated modules is detected, the test points can be greatly reduced, and the number of the serial-connected photovoltaic modules in each row of photovoltaic module integrated modules is 10 to 30; after a fault is found in each row, the photovoltaic modules of the photovoltaic module integrated modules are checked one by one. According to the photovoltaic module array monitor display provided by the invention, the power generation condition of each row of photovoltaic modules in the photovoltaic module array of a photovoltaic power station can be monitored, the fault can be accurately and quickly found; the photovoltaic module array monitor display also has the characteristics of reliable performance, low manufacturing cost and the like. Through the application of the monitor display, the power generation condition of each row of modules in the photovoltaic power station can be clearly seen, so that the power generation efficiency of the photovoltaic power station is improved, and the maintenance cost is reduced.
Description
technical field [0001] The invention belongs to the technical field of photovoltaic module power generation, and in particular relates to a photovoltaic module array monitoring display. Background technique [0002] Solar power generation can effectively reduce environmental pollution and create a clean environment. At the same time, solar energy is an inexhaustible and inexhaustible clean energy. Now solar power generation has been widely used all over the world, and large and small solar photovoltaic power stations have also emerged. Since the voltage of a single photovoltaic module is not high and the power is relatively small, solar photovoltaic power stations are usually composed of several photovoltaic modules connected in series to meet the voltage requirements to form a row, and then paralleled to meet the power requirements. Component array composition. These photovoltaic module arrays will have problems (open circuit or short circuit) in a certain row or a certai...
