The Aurora Stream Box is an original monitoring and communication component designed for integration with Aurora (Power-One / ABB) central inverters. This unit collects data from multiple PV strings, provides protection via internal fuses and surge arresters, and transmits performance information to supervisory control systems through RS-485 and digital inputs/outputs.

Engineered for medium to large-scale photovoltaic installations, the Stream Box combines string protection with advanced monitoring features, ensuring reliable operation, fast fault detection, and simplified maintenance of PV plants. It supports environmental sensors such as temperature (PT100), irradiance, wind, and cell temperature, making it an essential device for precise system performance analysis.
