A+ A+ A+ TUV Verified
The Nexun One was verified by TUV Rheinland and other third parties to match A+ A+ A+ Class for the IEC60904-9 Ed. 2 and Ed. 3 with extended-spectrum from 300-1200nm. Beyond the standard tests, spectral stability over flash is also assessed. TUV Verified LED solar simulator!
HJT Terminator
With its 500ms pulse and the Dynamic IV, no HJT will ever need more than a single flash to be accurately measured.
The Bi-directional Dynamic IV technology and 500ms pulse mean 100 points with each 5ms stabilization, allowing an accurate measure of the most capacitive technologies without complex fitting algorithm or curve shaping.
Active Electronic Load
The 4-quadrant active load allows for the most precise measurement with an accuracy of 0.05% FS.

HJT Temperature Coefficient
The Nexun One is the only system on the market that allows you to measure the highest hysteresis HJT panels can be measured in a single flash. Making the temperature coefficient measurement of these new technologies like a breeze.
Spectrum Tuning
The Nexun One, with 32 independent wavelengths enables full control of the spectrum.
Adjust each wavelength precisely, create your own spectrum, simulate regions like desert, city, or sunrise & sunset.
Activate specific junction for HJT, bringing new services to your laboratory.
Set your spectrum, and change in a single click!
Unrivaled Spectrum
Beat Xenon Spectral Match
The Nexun One beats even the best Xenon systems, thanks to its patented IR Technology. Xenon exhibit large peaks on the IR region, drastically increasing uncertainty as spectrometer cannot reliably measure massive peaks and may saturate / average.
Match the new Standard
The Nexun One ensures that you meet the highest industry standards. Its spectrum reaches A+ for both IEC60904-9 Ed. 2 and Ed. 3, with an SPD lower than 15% and SPC higher than 98% over the 300-1200nm range. Its spectral deviation is lower than Xenon and other LED solar simulators.

Proven Stability
The Nexun One is production-proven in 24/7, 15s cycle time and retains its A+ A+ A+ rating over time, in the harshest conditions, which is often not the case of other simulators thanks to advanced thermal management and precise, in-house designed, high accuracy electronic regulation.
Long Term Stability
The Nexun One has demonstrated higher long-term stability than its competitors in a production environment, after months of data analysis.
Light source Long Lifetime
With an LED lifetime of over 36’000’000 flashes; and the 1’500’000 flashes IR source; ensure the minimum maintenance requirements at the lowest ownership cost.
Industry’s most advanced software
The Nexun is powered by the industry’s most advanced software, with functionalities that speed up the lab process, improve traceability and work efficiency while limiting potential user errors.

Advanced Electronic Load
High Hysteresis
The load is optimized for the measurement of high-hysteresis technologies like HJT, ensuring the fastest capacitive discharge of the panel during the measurement.
True 4-point Kelvin Connections
At the difference of most loads on the market, where V- and I- are short-circuited, Avalon’s load has a true, 4-point Kelvin connection with fully isolated I and V channels.
Low Noise, 4’000 Points, 16 bits
The load uses fully independent channels for each of the measured Voltage, Current, and Irradiance. Powered by high speed, 16bit converter with a low-noise optimized front end, a single IV is measured of 4’000 points.
30A, 250V, Multiple Ranges
Measure panels up to 30A and 250V with measurement ranges of 30A, 10A, 4A, 1A, 0.2A and 250V, 180V, 120V, 60V, 15V, 1V
WPVS Channel
A WPVS Reference cell can be directly connected to the load, thanks to its trans-impedance amplifier, removing the needs of an external shunt resistor, further reducing uncertainties.
4 Raytek IR Temperature Sensor
You can connect up to 4 Infrared temperature sensors, ensuring precise monitoring of the temperature.
8 PT100 Channels
The optional PT100 box allows you to connect up to an 8 PT100 temperature probe for a precise measurement of the temperature coefficients.
0.05% Accuracy
The load is guaranteed to an accuracy of 0.05% to the selected measurement range, ensuring the lowest measurement uncertainties.
