6 FAQs about [Virtual current appears in photovoltaic combiner box]

What is a combiner box in a photovoltaic system?

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.

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.

Is the PV DC combiner box CE-compliant?

Carry our earthing and measures against short-cir-cuiting 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.

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 is a virtual central PV string inverter?

Virtual Central approach of PV string inverters – a cost benefit Compared to the traditional mounting arrangement where the inverter is fixed decentral at the end of each PV string the so called virtual central offers many benefits.
