The LED Flasher Built for Production, Labs, and Large Importers.
Instant, accurate module testing for companies that need reliable quality control without a full laboratory.
The J.v.G. LED Flasher is a versatile high-performance testing system designed for mass testing in PV production, as well as for labs, large importers, EPCs, installers, and solar plant operators. It operates fully automatically, delivers high-accuracy measurements, and ensures excellent repeatability—ideal for anyone who needs reliable and consistent quality data.
The system is available in multiple configurations:
- As a stand-alone unit, optimized for companies without a production line (importers, EPCs, universities, QA departments).
- Or fully integrated into an automated production line for maximum throughput and seamless operation.
Additionally, the Flasher can be supplied as a combined all-in-one solution—Flasher, Electroluminescence (EL), and Highpot in a single machine—or as an individual module (Flasher only, EL only, or Highpot only), depending on your testing requirements.

A Testing Solution Designed for Installers, EPCs, Importers, and Solar Operators
Most companies outside of module production have the same problem:
they install, import, or operate solar modules without ever verifying their quality.
The J.v.G. LED Flasher changes that completely.
Why It Matters for Large Installers & EPCs
- Stop installing modules with hidden defects
- Avoid costly replacements on rooftops and in the field
- Prove defects immediately — before installation
- Protect project timelines and reduce rework budgets
- Strengthen your reputation with verified, documented quality
Why It Matters for Importers & Distributors
- Test incoming containers
- Identify mixed-quality batches early
- Build leverage in negotiations using hard data
- Reduce warranty exposure and financial risk
- Increase trust with downstream customers
For companies who buy, install, or manage solar modules at scale, the LED Flasher becomes a profit-protection tool.
It prevents costly surprises, gives you control over supplier quality, and delivers the transparency needed to make informed decisions.
Why Leading Solar Companies Rely on the J.v.G. LED Flasher
With the innovative J.v.G. LED Basic 2.0 Flasher, each module is tested not just once, but five times in one go. The advantage is that the LED version is faster at measuring than normal XENON flashers.
