PV DC combiner boxes – compact, high-quality and cost-optimised

Our DC combiner boxes offer users the possibility to integrate short-circuit and overvoltage protection, as well string monitoring solutions (I,V, T and SPD and switch isolator status), for PV systems using central inverters with PV panels in trackers and fix tilt systems.

Weidmüller offers a trackrecord of DC combiner boxes higher than 150.000 units sold in all climate regions of the planet for more than 10 years.The experience and expertise in the DC engineering is used to provide high-end solutions covering the CAPEX and OPEX needs of the customer. Models equipped with string monitoring provide additional performance with voltage, current and temperature mesurement as well as SPD health and DC switch status. This helps to improve PR of plants and optimises the ROI.
