Customized Module IV Tester
The Customized Module IV Tester is a device specifically designed and optimized according to users' specific testing requirements (such as special module dimensions, specific testing standards, higher accuracy, or integrated production line needs). It can accurately capture and analyze the current-voltage (IV) characteristic curve of photovoltaic modules or other electronic components, used to evaluate their key performance parameters (such as maximum power point, open-circuit voltage, short-circuit current, fill factor, etc.) and quality status.
Product Features
Customization Capability: Exclusive optimized design for special dimensions, specific standards (e.g., new IEC standards), special environments (e.g., integration with high/low temperature chambers), or production line cycle times.
Measurement Performance: Emphasizes high accuracy (low error), high stability (good repeatability), and strong anti-interference capability, enabling the capture of subtle IV curve variations.
Analysis Function: Not only measures the curve but, more importantly, automatically, quickly, and accurately extracts and calculates all key performance parameters (e.g., Pmax, Voc, Isc, FF, Rs, Rsh, etc.) from the curve, and can perform preliminary quality judgments based on this (e.g., hidden cracks, hot spots, degradation, etc.).
Integration & Intelligence: Emphasizes that the device is easy to integrate into automated production lines (e.g., communication with loading/unloading robots, barcode systems) and is equipped with powerful software for data management, in-depth analysis, and report customization, providing an intuitive and user-friendly operation experience.

Product Applications
Production Line Full Inspection and Sorting: Performs 100% online power testing on each product in the module manufacturing process, enabling precise quality sorting (Grade A/B/C) based on parameters such as maximum power point (Pmax) and open-circuit voltage (Voc), ensuring factory output modules meet the ±3% power tolerance requirement. Simultaneously provides real-time feedback on welding or lamination defects through IV curve anomalies (e.g., steps, low fill factor).
Laboratory R&D and Certification: Used for ultimate efficiency verification of new cell technologies (HJT/perovskite, etc.), and quantitative analysis of performance degradation after reliability tests per IEC 61215 standards (such as damp heat cycling, PID aging), providing critical data support for technology iteration and product certification.
Power Plant Acceptance and Maintenance: Conducts sampling inspections of incoming module power during power plant construction (avoiding over 10% overstatement risks). During operation and maintenance, locates faults like hot spots and diode failures by correlating abnormal IV curves (multi-peak/slope) with infrared thermal imaging, and regularly assesses whether the module's average annual degradation rate exceeds the 0.8% safety threshold.
Decommissioned Module Recycling Assessment: Quickly tests the residual power generation capacity of second-hand modules (reaching 70%~85% of initial power), filters out modules suitable for refurbishment to prevent PID-degraded products from entering the market, and guides the reuse of high-power modules as whole units or the disassembly and recycling of silicon material/silver paste from low-power modules, maximizing resource value.
