6 FAQs about [Photovoltaic combiner box protection fuse]
What fuses are included in a PV DC combiner box?
The PV DC COMBINER BOX is provided with gPV fuses in accordance with IEC 60269-6:2010. Each design of combiner box contains the most suitable fuse rating specially selected for each project, depending on Isc of PV strings, on voltage rating and on ambient tem- peratures. Clamping range, min. / max. Wire connection cross section AWG, min. / max.
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 PV fuse & how does it work?
When three or more PV strings are connected in parallel, a PV fuse on each PV string will protect the PV modules and conductors from overcurrent faults and help minimize any safety hazards. The PV fuse will also isolate the faulted PV string so the balance of the PV system can continue to generate electricity.
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.
What is a solar combiner box?
Our solar combiner box is used professional wires that are especially for solar system. Built-in with 15A Rated Current Fuse, Surge Protective Device and 63A Air Circuit Breaker and a ground wire connector, the ground wire installation is available. 6pcs individual 15A rated fuse. Max current of single PV input array is 10A.
How do I connect the PV string combiner boxes?
To connect the PV strings, the string combiner boxes are equipped with either our SUNCLIX panel feed-throughs or with cable glands on Push-in terminal blocks. SUNCLIX connectors from Phoenix Contact and Push-in terminal blocks combine the advantages of easy installation with reliable and maintenance-free connection.
