Description

technical field [0001] The invention belongs to the technical field of photovoltaic power generation, and in particular relates to a photovoltaic wiring device, a power optimization system and a method, in particular to a photovoltaic module with a power optimization function, its engineering arrangement, and a corresponding power optimization method. Background technique [0002] A single solar cell cannot be directly used as a power source. To be used as a power source, several single cells must be connected in series or in parallel and tightly packaged into components. Photovoltaic modules (also called solar panels) are the core part of the solar power generation system and the most important part of the solar power generation system. [0003] At present, photovoltaic projects uniformly use a photovoltaic module mode for power optimization. From the perspective of module power monitoring and optimization, the monitoring accuracy is very low; if you want to complete the fi...
