Description

Solar string combiner boxes

A plug & play solution for solar installations

In a photovoltaic system, the modules are arranged in strings and fields depending on the type of inverter used, the total power and the technical characteristics of the modules.

ABB offers a plug & play solution that accommodates overcurrent protection devices, disconnectors and surge protective devices (SPDs) in one solar combiner box. Depending on the application, combiners are equipped with monitoring devices to measure current, voltage and temperature to ensure the availability of the strings and to maximize generation. The string combiner boxes form subsystems that can be standardized according to the number of strings, voltage and rated current.

ABB offers different product ranges, each dedicated to specific installation conditions with typical configurations.
