Get the key to success with a reliable measurement, gain credibility and trust from your clients.
Lowest Ownership Cost
Did you know, yearly usage of Xenon lamps can exceed US$30’000?
With the Nexun Pro, no Xenon lamps mean no hidden cost, no downtime for lamp replacement, and no lengthy uniformity adjustment.
Unmatched repeatability
Remember the days a PMax repeatability of 0.2% was considered good?
The Nexun Pro breaks a new record reaching PMax repeatability below 0.02%, a 10-fold improvement over the competition.
Only possible thanks to its:
Full-LED design
Ultra-stable Avalon’s In-House Proprietary Regulation Electronics and,
Avalon’s advanced high accuracy electronic load.
Thanks to its advanced LED Regulation and unmatched load accuracy, the Nexun Pro offers an industry unmatched repeatability even for large area half-cut panels.
HJT - The only accurate simulator
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.
Automated Uniformity Robot
Don’t waste time anymore, the fully automated uniformity robot maps the area automatically in minutes!
Even better, the software is able to self-adjust the uniformity, ensuring the best measurement.
Available for both vertical and horizontal design.
Diagnostic System
Auto Diagnostic
Ensure the system proper operation with the integrated diagnostic system where each led string is measured and checked to detect any faulty LED or issue in the driver unit.
Visual Inspection
It is also possible to illuminate the LED at low intensity per channel, allowing a rapid visual inspection.
Active Electronic Load
The 4-quadrant active load allows for the most precise measurement with an accuracy of 0.05% FS.
30A, 300V
0.05% FS
True 4-point kelvin with independent grounds
Independent sampling on each channel
2 Irradiance input, 4 IR Temperature input
3rd party calibration
Best Class Light Uniformity
The 150x150mm LED Matrix allows precise control of the light non-uniformity, no matter the active area size!
Everything is controlled by software, no hardware adjustment, no sticker, no paint!
Automated conveyor
Automated conveyor for production with minimal shading profile.
Easy adjustment
PLC integration
Low profile
Dual Light-Source for Bifacial Technology
Producing bifacial?
Ensure sure the quality of your solar panels by measuring both sides in a single flash within the production. Only a true measurement will have an accurate power determination, forget about the bifaciality factor, do it the correct way.
The Nexun Steady has a 300W/m2 AAA backside light-source option at the best price.
Affordable
We have put a lot of engineering to provide the best performance and the lowest cost. The Nexun Steady is the best performance/cost system you will ever find in the market, especially for technologies like PERC, HJT, or Bifacial.
Optional Thermal Chamber
15-75°C
The fully automatic thermal chamber allows measurement across 15-75°C.
Save time and work for your team!
HJT Temperature Coefficient
The Nexun Steady 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.
300 - 1200nm A+ Programmable Spectrum
Match Xenon Spectrum
The Nexun Steady is designed to match the Xenon spectrum while adding the advantage of the LEDs. Its deep-IR LEDs ensure that lightly covers up to 1’200nm.
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.
Internal Database, External Database, Measurement Drag & Drop, Curve Zooming, Raw data extraction, User Management, Real-Time Curves, Recipes Management… We get you covered!
Advanced Electronic Load
Dynamic IV
To measure the highest capacitive panels
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
External Calibration
Perform calibration to any external laboratory that has a Fluke 5500A Calibrator. No software is needed.
WPVS Transimpedance amplifier
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.
Double Irradiance Channel
Whether you use WPVS or bifacial, you can connect up to 2 reference cells.
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.
