Photovoltaic DC combiner box 380v physical picture

What is a combiner box in a photovoltaic system?

In a photovoltaic system, a combiner box acts as a central hub that consolidates and manages the direct current (DC) output of multiple solar panels. Its main purpose is to simplify the wiring structure, enhance system security and simplify maintenance procedures.

What is a DC combiner box?

Our DC combiner boxes offer users the possibility to integrate short-circuit and overvoltage protection, as well string monitoring solutions (I,V, T and SPD and switch isolator status), for PV systems using central inverters with PV panels in trackers and fix tilt systems.

Are PV DC combiner boxes CE-compliant?

The PV DC COMBINER BOX is CE-compliant in accord- ance with Directive 2014/35/EU (Low Voltage Directive) and with Directive 2014/30/EU (EMC Directive). PV DC COMBINER BOX is a complete range of tai- lor-made Level 1 combiner boxes for utility-scale photovol- taic systems.

How to connect a PV DC combiner box?

Pull down the cables to assure that all of them are well connected. The output connections depend on the design of each tailor-made PV DC COMBINER BOX. The output cables must be connected to the poles of the switch disconnector or to the terminals prepared for this purpose.

How does the PV DC combiner box with monitoring work?

By default, the PV DC COMBINER BOX with monitoring comes with the internal communications pre-wired. This means that there is a communication cable between the device and 3 terminals at the bottom side of the enclosure.

Does a PV combiner box have a DC disconnection switch?

The PV DC COMBINER BOX has a DC disconnection switch by default. The DC voltage of the switch depends on the voltage of the PV string. The switch disconnector mak- ing and breaking capacity (according to the IEC 60947-3) has been selected to assure that it can switch the circuit at full load at the maximum operating temperature.
