Latest Patents

One of Xiaodong Mei's latest patents is the "Safety detection device and method of grid-connected inverter." This invention provides a safety detection device applied in a photovoltaic inverter system, which includes a voltage detection circuit, a filter circuit, a comparison circuit, and a controller. The voltage detection circuit is designed to detect voltage between a specific point and the ground, or between the first terminal of any phase of the three-phase power grid and the ground. The filter circuit filters out the alternating current component of the detected voltage while retaining the direct current component. The comparison circuit compares this direct current component with a preset voltage value and transmits the result to the controller, which determines whether the alternating current side at the output terminal of the inverter has normal insulation.

Another notable patent is the "Central-string inverter device." This device includes a container housing multiple string inverters arranged in two rows on opposite sides. An intermediate duct is formed between these rows, with air outlets on the side walls and air inlets on the other sides or the bottom wall of the container. Pulling structures corresponding to the string inverters are also integrated into the design, allowing for easy installation and removal.
