GAK for PV systems on residential buildings

PV Next generator junction boxes for inverters MPP trackers are used to protect the DC side of a photovoltaic system. The generator junction boxes protect the inverter against overvoltages and thus fulfil the European directive CLC/TS 51643-32. In addition, these products offer the option of protecting the system against reverse currents and the option of combining strings in order to save cables during installation.
