  • Product Features:
    Despite its compact size, there is no compromise on heat dissipation or electrical safety standards. It features a streamlined internal layout for intuitive, simple operation. With a high waterproof rating, it withstands heavy rain and snow accumulation.

    Applications:
    Designed specifically for thin-film solar panels, foldable solar chargers, portable power supplies for outdoor camping, and small-scale DIY off-grid systems.

    FAQs and Solutions:
    Issue: Does the compact size lead to overheating?
    Solution: Thermal simulation was used during design for low-power loads; natural convection cooling is sufficient to maintain safe internal temperatures.

    Important Note: Strictly avoid overloading with high-power crystalline silicon modules; exceeding the rated current capacity can cause internal components to burn out.
