  • Product Features:
    Features a simple yet robust structure and is TÜV certified. The potting material offers excellent thermal conductivity, facilitating rapid heat dissipation for internal electronic components and ensuring long-term stability even under high-current operating conditions.

    Applications:
    Suitable for integration with standard large-scale industrial modules; performs exceptionally well in coastal high-humidity power plants and ground-mounted utility-scale solar farms.

    FAQs and Solutions:
    Issue: Does an uneven potting surface affect performance?
    Solution: The production line utilizes an automated precision dispensing system to ensure consistent sealing depth. Minor surface irregularities do not compromise the IP67/68-rated protection.

    Important Note: Once the potting and sealing process is complete, disassembly is strictly prohibited; doing so will permanently compromise the unit's original high-performance sealing integrity.
