The Core Advantages
Made of T2 oxygen-free copper with precision braiding process, low contact resistance reduces PV power transmission loss and improves power station efficiency, meeting the "cost reduction and efficiency improvement" needs of the PV industry.
Specifically designed for outdoor PV scenarios, resistant to UV, high and low temperatures, moisture and corrosion, avoiding product failure caused by harsh environmental factors.
Excellent flexibility can effectively absorb thermal expansion, contraction and mechanical vibration during inverter operation, protecting the connection terminals and avoiding connection breakage.
Supports small-batch customization, provides fast drawing and production, and can be customized according to the size, terminal type and insulation requirements of different PV inverters.
Standardized terminals can be directly fixed with bolts, no complicated welding required, saving installation time and labor costs.
Application Scenarios
- PV Inverters: String inverters, central inverters, micro-inverters (DC/AC side conductive connection).
- PV Power Stations: Outdoor ground-mounted PV power stations, rooftop PV power stations, distributed PV power stations.
- PV Supporting Equipment: PV combiner boxes, PV junction boxes, inverter cabinets.

Frequently Asked Questions
Q
What conductor material is used in the PV inverter braided flexible connector, and why?
The standard configuration uses T2 Oxygen-Free Copper (Cu≥99.95%), which offers excellent electrical conductivity and low contact resistance. This minimizes power transmission loss in PV systems and ensures long-term reliability. Tin-plated and silver-plated options are also available for enhanced corrosion resistance or higher-performance applications.
Q
What cross-sectional area range is available, and how do I choose the right size?
Standard configurations cover 25–200mm², with full-series customization available from 10–300mm². To select the correct size, confirm the operating current of your PV inverter and choose a cross-sectional area with a safety margin of at least 1.2 times the rated current. String inverters typically require 25–50mm², while high-power central inverters may need 100–300mm².
Q
Can the braided flexible connector be used in extreme outdoor environments?
Yes. The connector is specifically designed for outdoor PV applications. The standard operating temperature range is -40℃ to +150℃, with high-temperature customization available up to -60℃ to +180℃. The silicone rubber sheath is UV-resistant and anti-aging, making it suitable for ground-mounted and rooftop PV power stations in both cold and hot climates.
Q
What terminal types are supported, and can special terminals be customized?
The standard terminal type is OT/DT copper lugs (cold-pressed). Customizable options include special-shaped terminals, double-hole terminals, and waterproof terminals to suit various PV inverter DC and AC output terminal configurations. Please provide drawings or specifications when placing a custom order for accurate production.
Q
Is welding required during installation, and what is the typical lead time?
No welding is required. The standardized terminals are designed for direct bolt-fixing, which significantly reduces installation time and labor costs. For lead times, regular orders are fulfilled within 7 business days, and urgent orders can be completed within 3–5 days.
Q
Do you support small-batch or custom orders for specific PV inverter models?
Yes, small-batch customization is fully supported. You can specify the installation length (hole center distance), terminal type, hole diameter, surface treatment (bare copper, tin-plated, or silver-plated), and insulation requirements. Our team will provide fast drawing review and production to match the exact requirements of your PV inverter model.
