Overview

The MS-90 Plus+ a trackerless solar monitoring station. Built around the unique internal rotating mirror design of the MS-90 DNI Sensor, the MS-90 Plus+ adds the industry and ISO 9060:2018 class-leading MS-80S Class A Pyranometer, and an original C-Box smart interface, for complete DNI, GHI, and calculated DHI measurements.

A practical solution to the increasing diversity of solar power plant locations and Photovoltaic (PV) applications, the MS-90 Plus+ can easily be deployed on rooftops or other inaccessible areas, and is an incredibly robust solution for difficult to reach installations where regular maintenance may be difficult or impossible.

MS-90 Specifications

Description

MS-90 DNI Sensor

A revolutionary design with proven reliability, the internal rotating mirror of the MS-90 DNI Sensor is based on the hugely successful MS-093 sunshine duration meter, deployed across Japan for over 10 years at over 800 AMeDaS network weather stations. Designed to accurately measure Direct Normal Irradiance (DNI) without a sun-tracker, the MS-90 is ideal for solar energy monitoring systems and meteorological networks.
