May 10, 2024 · This guide delineates the essential steps for the proper installation and connection of a PV combiner box. 1. Strategic Planning and System Design: Initiate the process with a
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.
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 ofers 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.
Vertical, upright installation is mandatory; inverted installation is prohibited. Wall-mounted or column-mounted installations are recommended, ensuring the wall or column can support the combiner box’s weight. Install the combiner box’s support braces on the same horizontal plane to prevent long-term deformation.
The PV DC COMBINER BOX product range ofers 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.
This user manual gives the general overview about the complete range of PV DC COMBINER BOX, the individual components, their function as well as their correct handling. An individual datasheet providing the specific information is attached to each combiner box. These information speci-fies the original features of each combiner box.
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.
