  • Product Features:
    Compact size, high cost-effectiveness, and simple operation. It has passed rigorous TÜV testing and is designed for compatibility with both standard and double-glass modules. High-efficiency bypass diodes are integrated internally to prevent the hot-spot effect.

    Applications:
    Widely used in standard residential PV panels, transparent double-glass modules, and distributed systems where cost and size are critical factors.

    Common Issues and Solutions:
    Issue: Localized heating caused by partial shading.
    Solution: This indicates the bypass diode is engaging. The product's thermal design meets standards; operation is normal provided the temperature rise remains within permissible limits.

    Important Note: When adhering the unit to the backsheet, ensure the adhesive is applied evenly and smoothly to prevent seal failure caused by long-term temperature cycling.
