Innovative Solar Measurement Technology
The Sunmeter Pro Counter LED represents a significant advancement in photovoltaic measurement technology. This state of the art device functions as both an irradiance (W/m2) and irradiation (kWh/m2) sensor, providing comprehensive data for solar power & energy analysis. At its core is a high-quality monocrystalline photovoltaic cell, laminated with specialized anti-reflective glass designed for photovoltaic modules. This unique construction ensures superior measurement accuracy across all sun angles throughout the day, setting a new standard for reliability in the field.
Enhanced Performance Monitoring
Beyond its primary function as a photovoltaic (PV) reference sensor, the Sunmeter Pro Counter LED incorporates innovative features that elevate its utility for system integrators and monitoring professionals. A built-in counter system alerts users to any sensor resets, ensuring data integrity and measurement reliability over extended periods. This feature is particularly valuable for long-term performance ratio (P.R.) calculations, allowing for more accurate and dependable system evaluations.
Versatile Integration and Robust Design
Engineered for seamless integration into existing solar monitoring setups, the Sunmeter Pro Counter LED offers multiple output options to suit diverse system requirements. Its rugged aluminum casing and UV-resistant components ensure durability in harsh outdoor environments, while the standard M12 8-pin male IP67 code connector provides reliable, weatherproof connections. The device’s compact dimensions and included mounting clamp facilitate easy installation in various configurations, making it an ideal choice for both new installations and system upgrades.
Precision Calibration and Compliance
Each Sunmeter Pro Counter LED undergoes rigorous calibration against a first-class PV reference cell, with periodic recalibration performed by the DAKKS-accredited ISFH Institute. This meticulous process ensures compliance with key industry standards, including IEC 60904-2, 60904-4, 60904-10, IEC EN 61215, and EN 61215. The sensor’s broad input range for irradiance (0-1500 W/m2) adheres to IEC EN 61724-1 requirements, guaranteeing accurate measurements across diverse environmental conditions.
Diagnostics
Blue – (Power Supply) – 3s Pulse
Red – (RS 485) – Pulsating when signal are transmitted from Master
Green – (RS 485) – Pulsating when signal are matching speed & parity
Comprehensive After-Sales Support
Demonstrating our confidence in the Sunmeter Pro’s performance and our commitment to customer satisfaction, we offer an unparalleled support package. This includes a complimentary recalibration service after one year of use, as well as the immediate replacement of the sensor if its tolerance exceeds 3.5%. This guarantee provides peace of mind and ensures the continued accuracy of your measurements.
Accessories
- Temmeter
- Pulse Anemometer
- ENV Meter
- ENV PRO
- ENV4
- USB/RS485 interface cable
- USB/MICRO-USB smartphone adapter
- Sm configuration for Android smartphone and tablet SMCONFIG allows you to configure Sunmeter in the field from your Android smartphone. It is no longer necessary to bring the Sunmeter back to the laboratory for configuration.The software allows you to:
- configure Sunmeter.
- make a diagnosis of the basic functions.
- log irradiance, temperature and wind (Sunmeter Wind only) readings.
The software is available for free on this page in the downloads area. In addition to the software it is necessary to have a USB / RS485 converter, an adapter cable between microUSB/USB and a female connector M12 4 pin for Sunmeter.
In the Download area you can find a wiring diagram of our cable that connects Smartphone/Tablet or PC with the irradiance sensor, it takes and transforms the voltage present on the USB (Price on request). Alternatively, it is possible to use other cables with external power supply (9V battery).
