Die Wahl des Solarwechselrichters

Aufgrund der Vielfalt an Gebäuden wird dies zwangsläufig zu einer Vielfalt an Solarmodulinstallationen führen. In order to maximize the conversion efficiency of solar energy while taking into account the beautiful appearance of the building, this requires the diversification of our inverters to achieve the best way of solar energy. Konvertierung. The most common solar inverter methods in the world are: centralized inverters, string inverters, multi-string inverters and component inverters. Now we will analyze the applications of several inverters.

The component inverter is to connect each photovoltaic component to an inverter, and each component has a separate maximum power peak tracking, so that the component and the inverter are better matched. Usually used in 50W to 400W photovoltaic power plants, the total efficiency is lower than string inverters. Since it is connected in parallel at the AC, this increases the complexity of the wiring on the AC side and is difficult to maintain. Another issue that needs to be solved is how to connect to the grid more effectively. The simple way is to directly connect to the grid through an ordinary AC socket, which can reduce the cost and equipment installation, but often the safety standards of the grid may not allow it. In doing so, the power company may object to the power generation device being directly connected to the ordinary sockets of ordinary household users. Another factor related to safety is whether an isolation transformer (high frequency or low frequency) is required, or a transformerless inverter is allowed. DasWechselrichter
