What is a solar combiner box?

Talk to our team today to make the right choices. A solar combiner box is an electrical enclosure where multiple Solar circuit components are housed. Here in BENY, we offer custom solar combiner boxes to ensure that our clients’ preferences are met.

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.

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.

How do AFCI solar combiner boxes work?

BENY Electric’s AFCI solar combiners detect wide ranges of electrical arc faults to keep power systems from igniting, improving action responses against fires. Our DC+AC combiner boxes come with over-voltage and over-current protection for solar DC sides, and RCBO and AC SPD for AC side protection.

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.

What is a combiner box?

Our combiner box is waterproof, dustproof and anti-corrosion, resisting harsh conditions for long-term and uninterrupted use. We offer multiple strings input up to 24 solar strings, with a maximum of 30 A per string. Series Isolator Switches with a max voltage up to 1500V DC widely meet various demands from PV power systems.
