6 FAQs about [Photovoltaic combiner box selection calculation table]

How do I choose a photovoltaic (PV) combiner box?

When selecting a photovoltaic (PV) combiner box, several key parameters must be considered to ensure the efficient operation and safety stability of the PV power station.

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 solar combiner box?

The combiner box is equipped with input terminals connected to the DC output of the individual solar panels. These terminals are designed to accommodate the positive and negative wires from each panel.

How are PV DC combiner boxes tested?

PV DC combiner boxes are tested according to IEC-61439-2 and are constructed on the basis of the test results as well as assembled for the specific application. This ensures that each of the requirements of the target application is fully met.

Does the 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 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.
