CNKA 2 string solar combiner box FAQ

Q: What is a combiner box?

A: A combiner box serves as a central location for managing the wiring of multiple solar panels. By consolidating the connections, the combiner box creates a streamlined output that can be sent to an inverter or charge controller. This design not only ensures a cleaner appearance but also improves the efficiency and organization of the solar PV system.

Q: Where do you put a PV combiner box?

A: PV combiner boxes are typically installed between the solar panels and the inverters. Regular maintenance is advisable to prevent potential issues such as leaks.

Q: What is the voltage rating of DC MCBs?

 A: DC miniature circuit breakers (MCBs) are designed to operate within a voltage range of 12 to 1000 volts DC.
