Description

Technical Field

[0001] The invention relates to the technical field of solar photovoltaic power generation, in particular to a photovoltaic power station. Background Art

[0002] A photovoltaic power station is a facility that uses photovoltaic panels to convert solar energy into electrical energy. Direct current is converted into alternating current through an inverter and can be used for grid connection or energy storage. It has the advantages of being clean and sustainable, but it also faces the challenges of intermittency and high initial investment.

[0003] Traditional photovoltaic power stations directly convert sunlight energy into direct current (DC) through solar panels, and then convert DC into alternating current (AC) through inverters so that it can be connected to the power grid or used by users. Solar panels are composed of multiple photovoltaic cells, which generate current when exposed to light. The inverter not only realizes the conversion from DC to AC, but also has the maximum power point tracking (MPPT) function to ensure that the maximum power is obtained from the solar panels. The inverter is also responsible for synchronizing with the power grid, providing multiple safety protection measures, and monitoring the operating status of the system to ensure the efficient, safe and stable operation of the entire photovoltaic power station. However, it is difficult to add a power supply socket on the side of the control box when the above-mentioned photovoltaic power station outputs current, resulting in maintenance and repair personnel needing to carry additional portable power supplies or extension cords when performing operations, which increases the complexity and inconvenience of the operation. The temporary use of extension cords or portable power supplies will cause the line layout to be messy, increasing the risk of electric shock and fire. At the same time, when wiring over long distances, temporary power supply solutions will lead to reduced power transmission efficiency and increased line losses, thereby affecting the performance and efficiency of the entire device.
