How to install a surge protector in a photovoltaic combiner box
To connect a surge protector to an inverter that has an integrated fuse box, ensure that you bypass the internal fuses and connect to external string fuses. A clear wiring diagram helps installers understand the flow of current from each string to the. An electrical surge, also known as a transient overvoltage, is a sudden and short-duration increase in voltage within an electrical system. Although it lasts only microseconds, it can carry significant energy and stress connected equipment. more Audio tracks for some languages were automatically generated. In this video, I'll show you how to. According to NFPA 780 12. 3, if the system's inverter is more than 30 meters away from the nearest combiner or re-combiner box, a surge protector is required at the DC input end of the inverter. If there are string protectors, such as fuses, DC breakers, or string diodes, install the surge.
