World’s Best Repeatability

Sub 0.05% pmax repeatability

2-15s Cycle Time

HIGHEST throughput

TUV Rheinland - A+A+A+ Validated

The Nexun Pro solar simulator is verified by third parties to the highest class of the IEC60904-9 : 2020 Ed. 3, extended spectrum. The Nexun Pro is a TUV verified A+A+A+ led solar simulator.

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.

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

• Dark IV

• 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!

Guaranteed < 1% non-uniformity, typ. 0.6%.

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 Pro has a 300W/m2 AAA backside light-source option at the best price.

No Consumable

Xenon flash tube replacement can cost in excess of US25’000$ per year in production, especially for long-pulse systems. Avoid uncertain costs and reliance on suppliers with a consumable free system!

The Nexun Pro has no consumable!

Affordable

We have put a lot of engineering to provide the best performance and the lowest cost. The Nexun Pro is the best performance/cost system you will ever find in the market, especially for technologies like PERC, HJT, or Bifacial.

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!

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, 300V, 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.
