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.
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.
In every photovoltaic (PV) system, stable power generation relies on more than panels and inverters. Hidden behind the scenes is a critical piece of equipment: the PV combiner box. Though easy to overlook, this device plays a decisive role in current collection, circuit safety, surge protection, and intelligent monitoring.
