PV Next generator junction boxes for inverter MPP trackers are used to protect the DC side of a photovoltaic system. These junction boxes protect the inverter against overvoltages and thus comply with the European directive CLC/TS 51643-32. Additionally, these products offer the option of protecting the system against reverse currents and the ability to combine strings to save on cabling during installation.
