As to the photovoltaic grid-tie inverter, the input end is connected to the photovoltaic component and the output end is connected to the power grid. The component has only positive and negative poles, and it is not easy to wire incorrectly. Since the component is a certain distance away from the inverter, it is required to add an extension cable. The correct connection method is that the photovoltaic connector has a female connector on one side and a male connector on the other side, so that the positive and negative directions will not change. However, some green hands will also make the two connectors of the extension cable the same. If the power inverter is connected, the positive and negative poles will be reversed.
