Customer Questions & Answers
1. What are the rated voltage and current for the Winpower Solar Branch Connector?
The product is rated for up to 1500 V DC and supports a nominal current of 50 A, making it suitable for high-power solar panel configurations.
2. What cable sizes are compatible with the Winpower branch connector?
It supports solar cables in the size range of approximately 14 AWG to 10 AWG (roughly 2.5 mm² to 6 mm²), allowing connection of many standard PV module cables.
3. What does the IP68 rating mean for this connector?
IP68 indicates the connector is completely dust-tight and can withstand continuous immersion in water under specified conditions. That means excellent protection in harsh outdoor environments.
4. What materials and certifications are used in the Winpower connector?
It uses a tinned copper conductor for reliable electrical connectivity and a PPE/PPO insulation body. The unit is designed to meet TÜV, CE, and ISO standards for safe and reliable operation.
5. What temperature range can the connector handle?
It is specified for extreme environments, with operational limits from about -40 °C up to +85 °C, ensuring stable performance in both cold and hot outdoor settings.
6. How does the locking system work for the Winpower connector?
The connector includes a self-locking mechanism that ensures the plug remains firmly connected in the field. A special wrench tool is required to release the connection, preventing accidental disconnection.
7. Can I use the Winpower branch connector for both series and parallel connections in a PV array?
Yes — while the primary use is parallel connection of solar panels (to combine their outputs while maintaining system voltage), it may also work in certain series-parallel configurations as long as the system meets the rated voltage/current limits.
8. Is installation straightforward or does it require special tools or training?
Installation is designed to be quick and easy: no advanced tutorial is required for assembly. However, to disconnect the self-locking mechanism safely, the dedicated wrench tool is required.
9. What are the main application scenarios for the Winpower connector?
Typical uses include rooftop and ground-mounted PV systems, off-grid and hybrid solar installations, and any scenario where panels are being connected in parallel (3-to-1 branch) and high voltage (up to 1500 V) is involved.
10. Why should I choose the Winpower Solar Branch Connector over generic connectors?
Because it offers a combination of features: IP68 waterproofing, high current carrying capacity (50 A), solid copper terminals with reliable crimping, broad temperature range, and a secure locking system intended for long-term outdoor use. These features can reduce maintenance, improve system reliability, and offer safer connections in high-voltage solar applications.
