In order to reduce the cable connections between the PV components and the inverter, to improve reliability and to be easier to maintain, the combination box is generally required for large-scale three-phase grid-connected PV systems.
The PNI CBT-3 is specifically designed to meet this requirement.
The combination box creates a complete solution for a photovoltaic power generation system with inverter. By using a combination box, the user can combine a certain number of PV components with the same specifications into a single component group depending on the DC input voltage range of the inverter.
Technical specifications
PNI CBT-3 can be installed outdoors thanks to the IP65 degree of protection. The metal case prevents damage to the components from UV rays, acids, moisture, mold or rodents.
In case of interventions on the installation, PNI CBT-3 facilitates the interruption of the system and simplifies the connection of the wires.
