12 Input 1 Output DC Solar PV Combiner Boxes
Description of PV combiner box
12/1 PV combiner box bus synthetic DC input of 12 PV components to 1 output. Each channel is with a fuse. Output side is equipped with lightning protection and circuit breaker. It greatly simplify input wiring of DC power distribution cabinet and inverter. Realize lightning protecion, short circuit protection and grounding protection. PV combiner box divided into two types: intrlligent box and non-intelligent box . Intelligent PV combiner box is equipped with monitoring unit, then detect input current of each string, detect inside temperature, detect lightning protection status, detect circuit breaker status and summarize output voltage and so on.
Design and configuration strictly accordance with the "Technical specification for photovoltaic junction equipment" CGC/GF 037:2014.
Provide users with a safe, brief, beautiful and applicable photovoltaic system products.
The product adopts outdoor wall mounted type, which adapt to the harsh environment. In addition to the core components, the other can be customized by users requirements.
