The latest selling Zhechi Electric®Photovoltaic Array DC Solar Combiner Box from China to a junction box, which is an electrical enclosure that securely unites multiple wires and cables through various ports of entry. A solar combiner box combines the output of numerous strings of PV modules for connection to the inverter.
The Zhechi Electric® Photovoltaic Array DC Solar Combiner Box bus synthetic DC input of 8 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 Array DC Solar Combiner Box CGC/GF 037:2014.
