QuickSun 650

sun flasher for PV module production lines

QuickSun 650 sun flasher for production lines

High capacity and precise PV module testing

The QuickSun 650 is a fully automated and highly productive class A+A+A+ sun flasher. Thanks to the outstanding performance and throughput speed, QuickSun 650 is an ideal solution for mass production of solar panels.

The sun flasher is compatible with Endeas All-in-One technology. This means that besides I-V testing, the system performs EL imaging, bypass diode test, electrical safety tests, and even optical inspection if needed. Less machines translates into fewer operators, lowest total cost of ownership and higher production uptime.

  • A+A+A+ sun flasher with optional EL, electrical safety, and bypass diode tests
  • Accurate results for the high efficiency modules
  • Fully automated in-feed, out-feed, and contacting
  • Low total cost of ownership
  • Compatible with modules sizes up to 270 cm x 140 cm

Sun flasher

QuickSun 650-series sun flashers achieve A+A+A+ classification according to IEC 60904-9 Ed.3. The outstanding measurement stability provides power measurement repeatability smaller than 0.1% guaranteeing best value for the produced modules, and high quality data for product development and Industry 4.0 process control. Even the high efficiency HJT, TOPCon, IBC, etc. modules are measured accurately with optimized length flash pulse and proprietary Capacitance Compensation (CAC) method.

EL imaging and Bypass Diode Test

A high resolution EL imaging with optional deep learning analysis and sorting software can be integrated into the sun flasher. By adding cost effective bypass diode test to the package, even further quality improvements are made and operation costs reduced.

Electrical Safety

QuickSun 650 has the capability to perform hipot and ground continuity testing. The actual leakage current is measured with a sensitive enough instrument that enables a run-time diagnosis of both contacting reliability and real module leakage characteristics. A 100% coverage of electrical safety testing for UL certification is achieved.
