Product Introduction of 6 Strings Combiner Box PV Array Combiner Box 6 Into 1 Solar Junction Box
In the solar power system, in order to decrease the connecting line, easy maintenance, reduce losses, optimize system structure, improving the safety and reliability of items, the PV combiner box is usually in need between the solar panels and inverter.
Except the PV junction function, the PV combiner box should also have reverse current prevention, over-current protection, over-voltage protection, lightning protection etc. a series of perfect protection functions, meanwhile checking the running state, current, voltage and power after junction, arrester state, collection of DC circuit breaker state and Arc detection, leakage detection (optional) and so on.
The PV combiner box we manufacture is equipped with all the functions mentioned above, configuration with on grid/off grid solar inverter to make up a complete set of solar power system.
When choose the PV combiner box, based on the input DC voltage range and output power of inverter, certain qty of panels will be connected in series as a string, certain strings in parallel will connect to the PV combiner box for junction, via control of circuit breaker and protection of arrester, then feed to the inverter.
A PV Combiner Box simplifies the connection between your solar panels and the inverter. It helps decrease the number of connecting lines, makes system maintenance easier, reduces power losses, optimizes system structure, and increases the overall safety and reliability of the installation.
It features comprehensive protective functions, including reverse current prevention, over-current protection, over-voltage protection, and lightning surge protection. It also features DC circuit breaker output control and built-in fuse protection for each string.
Yes, this PV combiner box is designed for outdoor installation and comes with an IP65 protection rating, ensuring it is dustproof and protected against water jets under harsh outdoor environmental conditions.
It supports a maximum of 24 input strings with a nominal current of 10A per string (maximum 15A). The total output current capacity is 250A with a maximum system voltage rating of 1000Vdc.
Yes, it features an isolated RS485 communication port that supports the standard MODBUS-RTU protocol, allowing users to remotely monitor system data, currents, voltages, and device status.
The combiner box features real-time monitoring of harmful arcs in the DC circuit. If a dangerous arc is detected, the built-in alarm triggers immediately, cutting off the fault circuit via the trip switch to prevent fire hazards before they start.
