Micro-inverters are devices that enable the conversion of direct current to alternating current from one or more PV modules. Unlike standard string inverters, which are placed further away from the modules, for example, on a wall in the service room, micro-inverters are fitted directly underneath the PV module. This minimises losses as less DC wiring is required, and it cuts out the cost of DC circuit protectors which are needed for string inverters. Such configuration significantly improves the installation’s safety as the maximum DC voltage that flows through the system is that of a single module. In addition, there is no need for any protection on the DC side. Micro-inverters are connected in parallel to one or three phases of AC wiring that leads directly to an AC switchboard.
