► Supported by a worldwide calibration organisation for the lowest total cost of ownership

SR200-D1: industrial-grade, high-accuracy and reliable

SR200-D1 may look like its predecessor, but in many ways it is a completely new instrument. We built upon the measurement capabilities of the earlier pyranometer model SR20 and tailored the SR200-D1 pyranometer to its most common applications in PV system performance monitoring systems and meteorological stations.

SR200-D1 complies with – Industrial-grade – Immunity, Emission, Electrical, Environmental and Safety requirements for use in these outdoor and industrial environments, greatly improving measurement reliability. Ease of operation is further enhanced through extended functionality and diagnostics.

PV System performance monitoring: IEC 61724-1 Class A compliant

SR200-D1 complies with IEC requirements for “Class A” PV system performance monitoring, for climates in which dew and frost are not an issue. If you need a pyranometer that complies with all locations and climatic conditions, consider the SR300-D1 pyranometer.

Immunity to high voltages and currents - surges

SR200-D1 is tested and classified for Industrial Environments according to IEC 61326-1 and IEC 61000-6-2. When designing a measuring system, pyranometer users may reach several levels of immunity.

With the optional Surge Protection Device SPD01 this immunity can be increased to 4 kV. Up to 3 pyranometers can be protected with a single SPD01. A third-party SPD with similar specifications may be used instead.

To attain the required level of immunity for a given installation, some general system components should be included, such as:

lightning protection system
earthing and grounding network
external surge protection in addition to the native on-board sensor protection

Electrical safety in the workplace

A PV power plant is a potentially hazardous workplace environment. To comply with safety regulations, SR200-D1 features a dedicated earthing terminal for connection to protective earth. When the pyranometer is isolated from the mounting platform, it should still be properly earthed via this terminal. SR200-D1 allows system designers to comply with safety regulations. These are often based on EU and US electrical safety standards such as:

EN-50110 Operation of Electrical Installations
NFPA 70 National Electrical Code (NEC)
