The Zhechi Electric® Outdoor Solar Energy PV DC Distribution Box which is in stock and provides free sample Up to 24 photovoltaic battery component on the DC input bus synthetic 1 output is CLBDHL-24 photovoltaic junction box, each channel is equipped with a fuse, the outside is equipped with a fuse, the output is equipped with lightning protection and breaker, simplify the input wiring of DC power distribution cabinet and inverter, Provides lightning protection, short circuit protection and grounding protection.
Junction box is divided into two types: intelligent and non intelligent. Smart photovoltaic junction box internal loading. Bus monitoring each PV string input current, the summary output voltage, status of lightning protection device and circuit breaker status. The inside of the device layout concise, orderly and reasonable arrangement of wires, High reliability, simple maintenance.outdoor wall hanging type installation, to adapt to all kinds of bad environment. In addition to the standard material and size can be customized according to user requirements.
Junction box production grade reaches IP65,can meet the requirement of outdoor wall mounted sealed cabinet.
To meet the simultaneous access to multiple solar battery pack, each is positive ,negative terminal connected to the road for a dedicated fuse wire.
The use of photovoltaic special high-voltage direct current fuse to protect the positive and negative poles the same time.
The use of photovoltaic special high -voltage lightning protection device can meet the positive pole to the ground,the negative pole to the ground,the working voltage to DC 1500v.
The bus can access the largest solar battery group open circuit voltage(maximum DC voltage)is more than 1500v(Including1500v).
The bus control module using reliable performance of the Honeywell HoLZER Component(DC CT sensor) on each road pv string of current monitoring. Alarm and local fault location, and through the RS485 Series communication.
The independent measurement of the current amount of PV array can be realized.
The analysis of the current, the fault of the lightning protection .
Junction box and control module can measure the voltage pf photovoltaic array. Battery plate temperature measurement of lightning protector and output Medallion status monitoring.
With the external interface part of the lightning protection.
Can receive the parameters of the local monitoring deviceto download, analysis and processin.
12.Bus communication power supply can be selected from the external power suppply or by the bus itself provides power, the site can not be used for power supply cabling.
