6 FAQs about [Photovoltaic DC combiner box technical agreement]
What is a PV DC combiner box?
PV DC COMBINER BOX is a complete range of tai- lor-made Level 1 combiner boxes for utility-scale photovol- taic systems. The combiner boxes are installed to join and protect the DC strings that go from the PV panels to the solar inverter. The PV DC COMBINER BOX product range offers solu- tions from 8 to 32 inputs and 1 or 2 outputs.
What is a solar combiner box?
The combiner boxes are installed to join and protect the DC strings that go from the PV panels to the solar inverter. The PV DC COMBINER BOX product range offers solu- tions from 8 to 32 inputs and 1 or 2 outputs. These can be designed for systems with string voltage of 1000 or 1500 V DC.
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.
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.
How do I connect a DC combiner box to a solar inverter?
The output cables must be connected to a Level 2 combiner box, which will join DC+ and DC- from other Level 1 combiner boxes, or directly to the solar inverter. The enclosure of the PV DC COMBINER BOX is made of Glass Fibre Reinforced Polyester (GFRP). The en- closure provides IP65 and IK07 or higher in accordance with IEC 62208.
Do I need a general inspection on the PV DC combiner box?
It is recommended to carry out a general inspection on the PV DC COMBINER BOX and the status of the installation. The installation must comply with either local and interna- tional regulations. All cables are in good condition. All connections of cables to the terminals are correct.
