Remarkably, the integration of an external-fuse setup amalgamates the functions of traditional fuses, MC4 connectors, and cable glands, leading to component reduction and operational simplification.
Furthermore, our combiner boxes are fortified with SMC fiberglass-reinforced plastic enclosures, a superior alternative to metal counterparts. These SMC boxes endure rigorous third-party testing, demonstrating resistance against acids, alkalis, salt spray, and ultraviolet exposure. After enduring 2,080 hours of high and low-temperature aging tests, these boxes achieve an IP67 protection rating, coupled with a steel toughness of IK10. Such a robust construction establishes them as the paramount choice, in line with 25 years of photovoltaic industry standards.
