Description

technical field [0001] The invention relates to the technical field of photovoltaic modules, in particular to a photovoltaic module fault diagnosis device and method based on maximum power point calculation. Background technique [0002] The function of the photovoltaic module is to convert solar energy into electrical energy, and store it in the battery, or drive the load to work. However, with the use of micro-inverters, the current source of the photovoltaic module can be directly converted into a voltage source of about 40V, which can be used to drive electrical appliances in our lives. At the same time, photovoltaic modules are constantly innovating. Since photovoltaic modules are called made in China in the industry, they should be created in China, and then there are upgraded and innovative products of photovoltaic modules, such as photovoltaic ceramic tiles and photovoltaic color steel tiles. These products can directly replace traditional Building material tiles al...

However, long-term operation of photovoltaic modules is prone to various operational failures

[0004] At present, the fault diagnosis devices used for photovoltaic modules on the market are often complex in structure, low in use value, unable to detect the power of photovoltaic modules in real time, and cannot report to the police in time, and the fault handling effect is poor. The detection speed is slow, unable to meet the needs of today's use, low performance and poor promotion in the field of peers
