Resumen de: WO2026148753A1
An inverter layout method, system, and apparatus. In the solution, photovoltaic module groups are first grouped on the basis of position information of photovoltaic modules in a power station, and a distance between any two photovoltaic modules in the same photovoltaic module group is less than a first predefined distance; and the photovoltaic modules in the same photovoltaic module group are connected in series and/or in parallel, and then connected to a same inverter. Since each photovoltaic module group comprises a plurality of photovoltaic modules, and the distance between the photovoltaic modules in the same photovoltaic module group is short, the plurality of photovoltaic modules can be connected to a single inverter, such that the same inverter inverts into alternating current direct current output by the plurality of photovoltaic modules. Thus, the present application allows for automatic inverter layout based on a position of each photovoltaic module, ensuring relatively short distances between photovoltaic modules connected to a single inverter, and allowing for proper inverter allocation and high layout efficiency while reducing inverter configuration costs.
