*3.2. Micro-Inverters*

For the case of micro-inverters, the system improves over several aspects. The problem of partial shading is now solved due to the distributed MPPT. Micro-inverters allow the fitting inside the frame of the BIPV module, thus becoming a real MLC. This combination is commonly referred to as an AC module. Micro-inverters are still coupled to the AC grid, making them vulnerable to AC grid disturbances. This is a major drawback given that the MLC is not difficult to reach after installation. An overvoltage on the AC grid could, thus, lead to a shutdown of the entire BIPV installation without the possibility to repair. From a reliability point of view, the major drawback of micro-inverters is probably the large electrolytic capacitors that are required to buffer the power output ripple at twice the switching frequency [44].

In literature, only one example is found that reports the use of micro-inverters. This is the case for the Copenhagen International School in Denmark [87].
