Smart I-V curve diagnosis

Product Description

For commercial and industrial (C&I) rooftop solar projects, manually inspecting and detecting faulty or shaded solar panels is always challenging due to the large roof areas and the safety risks of climbing. Huawei’s Smart I-V Curve Diagnosis feature fully automates this process through online data analysis. With just a single remote click, the system scans the entire PV array, identifies low-performance strings, and exports immediate troubleshooting reports.

Key features:

• One-Click Online Operation: The entire scanning process is performed 100% remotely via an application or Web interface. Business owners no longer need to incur costs for hiring experts or using handheld testing equipment on-site.

• Ultra-Fast Diagnosis Speed: The system allows for the completion of online scanning for an entire 5MW plant in just 5 minutes. Detailed result reports with analysis are automatically generated within 15 minutes.

• Automatic Detection of Diverse Faults: The smart algorithm automatically and accurately identifies different types of technical faults in solar strings and provides specific troubleshooting recommendations for each issue.

• Real-Time Alarms and Push Notifications: Synchronized connection with the FusionSolar management system pushes fault alerts immediately upon detection, helping Hoa Nam Energy’s technical team or factory owners proactively prevent yield loss risks.

• International Quality Certification: Huawei’s string-level Smart I-V Curve Diagnosis technology has been rigorously tested and certified by the prestigious TÜV Rheinland organization.

Why Choose This Solution?

• Ultra-Fast PV Layout Mapping: Supporting automatic device identification and mapping the layout locations of photovoltaic (PV) modules on the system diagram in just 5 seconds.

• Module-Level Detailed Display: When combined with the Smart PV Optimizer, the system enables visual monitoring of the operational status down to each individual solar module on a graphical interface.

• Multi-Site Centralized Management: Allowing investors to self-monitor and perform centralized fault diagnosis for multiple factories and plants simultaneously on a single digital map.

• Repair Workflow Automation: Supporting online troubleshooting ticket creation and instant fault localization, helping to optimize technical personnel and significantly reduce operating expenses (OPEX).

• Visual ROI Estimation Reports: The system automatically aggregates periodic reports, supporting financial efficiency and cash flow analysis based on the actual operating conditions of the system.

• Synchronized C&I Hardware Ecosystem: Operating with perfect compatibility with Huawei commercial inverters (such as SUN2000-30/40/50KTL-M3, SUN2000-100KTL…) via Smart Dongle or SmartLogger connection.
