What is a DC combiner box?

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.

What is a solar combiner box?

A solar combiner box is mainly used to collect the direct current generated by photovoltaic modules and distribute it to subsequent inverters or other equipment. In a photovoltaic power generation system, photovoltaic cell modules form a series through stringing, and then these series are connected to the photovoltaic combiner box via cables.

Does ABB offer prewired solar combiner boxes?

ABB also offers prewired solar combiner boxes with not only string protection, surge protection and disconnection but also with additional monitoring devices. The monitoring device CMS PV collects all main information such as string current, voltage and temperature in one device.

Should solar combiner boxes have surge protection?

Photovoltaic (PV) Solar Combiner Boxes should have surge protection features to avoid impacts from thunderstorms on entire solar energy systems. In on-grid systems, solar combiner boxes should have reverse flow protection features preventing current flowing back into grid causing harm.

What is a PV next combiner box?

Our flexible and compact PV Next combiner box was honored with the German Design Award 2023 in Gold. A modular design, safe thermal and mechanical functionality of all components and flexible connection types are just some of the advantages that make installation, maintenance and monitoring with PV Next easy.

How are PV DC combiner boxes tested?

PV DC combiner boxes are tested according to IEC-61439-2 and are constructed on the basis of the test results as well as assembled for the specific application. This ensures that each of the requirements of the target application is fully met.
