Resumen
As a digital-only version of the original SunSentry™, the SunSentry 20 features an AC power input inside the main enclosure instead of a separate AC pull box. Specifically designed to support the irradiance and weather reporting needs of utility-scale solar farms, this solar operational meteorological (met) monitoring station provides weather reporting data for a wide variety of applications.
The SunSentry 20 establishes a new chapter of met station design and ease of use. Each station is standardized, stocked, follows the industry requirements of IEC 61724-1:2021, and exceeds IEC 61000-4-5 Class 4 surge immunity levels. Station installation is made easy via pile-mountable hardware, bulkhead connectors, and the renowned SunSentry web user interface (UI).
Note: Some of the SunSentry 20 images are shown with optional mounting hardware, solar panels, and sensors that are sold separately.

Compatibilidad
The SunSentry 20 is digital, RS-485 compatible only.
The SunSentry 20 supports a single sensor array in addition to a standard array of met sensors. Adapters must be used with Campbell Scientific's RS485CBL system. Sensors must be daisy-chained to the SunSentry 20 for fast, simple installation.
