Solar Combiner Box

A solar combiner box is a central junction box used in a photovoltaic (PV) system. It combines several solar strings coming from the same array, and then sends this combined current to the inverter. Combiner boxes also play a crucial role in monitoring the system, as it includes separate breakers for each of the solar strings, allowing you to immediately identify and troubleshoot any problems within the system. Internal lightning protection is provided in some models, ensuring the safety of the solar modules and the combiner box electronics in the event of a power surge.
