PLC handshake
Standard digital I/O and fieldbus options (Profinet, EtherCAT, Modbus TCP) so EVO drops into the line as just another station. Recipe selection, start/stop, status and fault signals are exposed where your line controller expects them.
Nexun EVO
Built for the production line.
A cost-effective horizontal LED solar simulator engineered for PV factories. A+ A+ A+ class, cycle time down to 10 s, no consumables, fully automatic with PLC, conveyor, barcode and MES integration. Auto-calibration is handled on-board by a uniformity robot, so the line keeps moving and the data stays valid.

Why a different machine
A factory simulator, not a lab simulator in a factory.
Production-line measurement is a different problem from lab measurement. Cycle time dominates over uncertainty budget. Up-time dominates over peak performance. Integration with your line controller dominates over rich graphical outputs. EVO is the Nexun engineered around that reality, without giving up the accuracy that makes the data worth collecting.
- 01
Designed for the production line, not the lab.
Most LED simulators are built for laboratories and bolted into production as an afterthought. EVO is the opposite: a horizontal in-line layout, throughput-first cycle time, and a control surface that speaks PLC and MES out of the box, so it integrates instead of disrupts.
- 02
Down to 10 s cycle time, with the lights off.
EVO can be tuned down to ~10 s per module on a typical c-Si line, including conveyor in/out, flash, IV computation and result push. That is the kind of cycle time that lets a single test station match the throughput of a whole factory string.
- 03
No consumables. No surprises.
There are no xenon bulbs, no flash lamps, no scheduled lamp-replacement downtimes, no spectral drift to correct between shifts. The LED engine is rated for the full lifetime of the simulator, so every flash is the same flash, the data stays consistent, and your maintenance window is whatever your auto-cal cycle takes.
Factory integration
Speaks your factory’s language.
EVO is engineered as a node on your factory network, not as an island that someone has to walk to. Every part of the test cycle, loading, measurement, decision, push, runs through the systems your line already uses.
Conveyor sync
EVO is built to be fed and emptied by your conveyor or shuttle. Module presence, alignment, and clamp readiness are tracked so the flash only fires when the panel is exactly where it needs to be. No operator on the loop.
Barcode scanner
On-board scanner reads the module barcode at entry. The scanner ties the IV result, EL image and calibration record to the serial number automatically, so traceability is guaranteed without manual data entry.
MES & external DB
Bidirectional MES connectivity for recipe routing, bin-out decisions and full-result push. Results can also stream into an external database (SQL, S3, in-house data lake) in real time, with the schema fixed by you, not by us.
Fully automatic
EVO is designed to run unattended. The combination of PLC handshake, conveyor sync, barcode ingest and MES recipes means the test station does its own loading, measurement, decision and unloading. Operators handle exceptions, not flashes.
Uniformity robot
An on-board uniformity robot scans the active area on a periodic schedule with a calibrated reference cell. The result drives an auto-calibration cycle, so spectral and spatial drift is corrected before it shows up in your factory data.
Auto-calibration
Stays in spec without you on it.
The on-board uniformity robot replaces the manual reference flashes that normally eat into a maintenance shift. It scans the active area on a schedule you set, the calibration cycle that follows is short, and the result is automatic, traceable, and logged. Your factory data stays valid without anyone touching the simulator.
Uniformity scan
Robotic positioner moves a calibrated reference cell across the active area, sampling the flash uniformity at every point of interest.
Auto-cal cycle
Drift on a band or a region triggers a corrective cycle; the simulator updates its working calibration without operator intervention.
Audit log
Every scan and every correction is logged and timestamped, so the factory's quality record is intact for audits and certification.
Where EVO fits
For factories that hate downtime.
EVO is the right answer when the simulator is part of a line, not a destination. Where the operator is upstream and downstream of it, not in front of it.
