Module inversion

Module inverter is to connect each PV module with an inverter, and each module has a separate maximum power peak tracking, so that the module can better cooperate with the inverter. It is usually used in photovoltaic power stations of 50W to 400W, and the overall efficiency is lower than that of string inverters. Because it is connected in parallel at the AC side, this increases the complexity of the connection at the AC side and makes maintenance difficult. Another problem to be solved is how to connect to the grid more effectively. The simple way is to connect to the grid directly through ordinary AC sockets, which can reduce costs and equipment installation. However, the safety standards of power grids around the country may not allow this. Power companies may object to connecting power generation devices directly to ordinary household users' sockets. Another factor related to safety is whether isolation transformer (high frequency or low frequency) is required or transformer free inverter is allowed. This inverter is most widely used in glass curtain wall.
