What is a DC combiner box?
Our DC combiner boxes offer users the possibility to integrate short-circuit and overvoltage protection, as well string monitoring solutions (I,V, T and SPD and switch isolator status), for PV systems using central inverters with PV panels in trackers and fix tilt systems.
Each combiner box comes with advanced features including up to 1500V 400A UL Listed DC Disconnects and UL Listed Fuses from 10A to 56A, delivering unbeatable performance with utmost safety.
The size of the grounding conductor is a critical factor. It needs to be large enough to carry the fault current safely to the ground. . A pv combiner box serves as the central collection point for the direct current (DC) electricity generated by groups of solar panels, known as strings. After running the 6 awg wire to the panel array for grounding it has been said to connect that 6 awg to the ground bar inside the combiner and then through conduit (along with panel array wires) and connect that 6 awg wire to the inverter ground.
