FAQs 6

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.

What is a DC box?

Protect and keep an eye on the arrays of your PV installation. The DC Box is a PV array combiner box installed next to the ConextTM Core XC inverter, providing protection and supervision of the PV plant performance. Offer range with 6/10 inputs and a maximum output current of 1600A STC to fit with a large number of PV plant designs

What are the NEC standards for outdoor PV power generation?

This high-safety and reliability outdoor PV power generation system component meets the NEC 2017/2020 standards, with 1500V DC voltage, output circuit breaker ratings up to 400A or 500A, and NEMA 4X housing protection class. It is ideal for parallel series combination and current protection in large-scale photovoltaic power stations.

How many inputs & outputs does a PV DC combiner box have?

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. The necessary string cables (+ and -) are to be connected at the inputs whereas one or two DC+ and DC- main ca- bles will be at the output side.

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 many DC output cables per polarity to connect the inverter?

Up to 4 x 300 mm2 DC output cables per polarity to connect the inverter DC Box // PV array combiner box. Specifications are subject to change without notice. (1)DC Box equipped with the fuses listed below. (2)For monitored models. (3)Fuses not provided with product, to be ordered separately.
