Combiner and Junction boxes RP

General purpose DC boxes for Photovoltaic application. These boards are intended for all variants of boards at DC side of PV systems. Boxes are TTA type tested according to EN 61439-1 and EN 61439-2. Maximum current is 630 A, maximum nominal voltage 1000 V DC. These boards are generally offered as tailor made solution based on customer’s requirement. In addition to TTA based CE Declaration of conformity, every produced board is equipped also with final test protocol.

As the equipment, Noark PV components are used – Miniature Circuit Breakers Ex9BP, Surge Protective Devices Ex9UP, Installation Isolators Ex9IP, Fuse Disconnectors Ex9FP, Moulded Case Circuit Breakers Ex9MD, Switch Disconnectors Ex9MSD DC, monitoring systems SUP etc.

Typical configurations are Combiner box, Junction box, String box, SPD protection box etc. All versions can be also equipped with monitoring system SUP with ModBus-RTU communication via RS-485.
