FAQ

Q: How many specifications do your energy storage connectors cover?

A: Sanco offers three main categories of energy storage connectors: quick-connect connectors, stacking connectors, and bolt-type connectors. They support current ratings from 60A to 600A and are compatible with wire cross-sections ranging from 10 mm² to 185 mm².
Q: How do I choose the right connector for my energy storage system?

A: Selection should primarily focus on four key parameters: rated voltage (e.g., 1000V DC, 1500V DC, or 2000V DC), rated current (e.g., 120A, 250A, 400A, 600A), application scenario (indoor/outdoor, commercial & industrial/large-scale energy storage), and compatible wire size. Always ensure the connector specifications match your system requirements.
Q: What are your competitive advantages? Why should I choose your products?

A: Sanco is a large-scale manufacturer capable of independently handling the entire production process—from initial design to terminal and plastic housing production, and final assembly. This allows us to ensure consistent quality while offering lower-cost products. Additionally, we maintain long-term partnerships with many leading global battery manufacturers and energy storage integrators.
Q: What is the IP rating of your connectors?

A: Our connectors achieve an IP67 rating (dust-tight and capable of withstanding temporary immersion), ensuring safety and long-term reliability.
Q: Are the connectors certified?

A: Yes, our energy storage connectors are dual-certified by TÜV and UL, ensuring compliance with certification requirements in export destinations
