Photovoltaic Combiner Box

PV Combiner Box
PV combiner box also known as solar combiner box, is a critical component in solar photovoltaic systems. It is designed to consolidate the direct current (DC) output from multiple solar panels into a single, manageable output, facilitating connection to inverters or other devices. The primary functions of a photovoltaic combiner box include enhancing system protection, simplifying wiring, reducing installation costs, and providing real-time monitoring and various protective measures.

SI-CD Series DC Lightning Protection PV Combiner Box

Higher efficiency.  

Reliable and durable.  

Easy to use.  

Easy to maintain.  

SI-CD Series PV Combiner Box Overview

The SI-CD series PV combiner box is used to connect a number of photovoltaic panels with the same specifications into photovoltaic series, and then these series are connected in parallel to the box. The DC power collected by the convergence box will be used by the controller, DC distribution cabinet, solar inverter, AC distribution cabinet and other equipments to form a complete photovoltaic power generation system.

Key Features of SI-CD Series PV Combiner Box

1. IP65/IP66 protection rating, fearless in extreme weather
2. Integrated lightning protection, constantly shielding against storms
3. Operating temperature range: -20℃~60℃, humidity range: 0~95%
