A cost effective system combining MS-90 and MS-80 for DNI, GHI and DHI data without sun tracker. MS-90 Plus+ is the combination of two innovative irradiance instruments from EKO: MS-90 DNI sensor and the fast response Class A pyranometer MS-80. These two instruments are connected via a special interface box (C-Box) with a GPS receiver and an processing unit. The system accurately measures DNI and GHI and calculates Diffuse irradiance (DHI) from the measurement data and the sun position.
The system provides a digital output signal (Modbus 485 RTU) and can be easily connected to various data acquisition systems in solar energy projects and meteorological stations (dataloggers, inverters, SCADA etc). It can also be connected to a PC.
The MS-90 DNI sensor has a broad spectral response (300-2500 nm) and is calibrated outdoors with a pyrheliometer.
