PRODUCT QUESTIONS产品问答
Product & customization questions产品与定制常见问题
Is every black double-insulated cable suitable for PV use?所有黑色双层绝缘电缆都适合光伏使用吗？
No. Cable suitability depends on its complete designation, voltage, conductor construction, materials, certification or listing scope, temperature, sunlight and wet-location properties, flame behavior and the intended installation rules. Appearance alone is not evidence.不是。线材适用性取决于完整牌号、电压、导体结构、材料、认证或列名范围、温度、耐日光与潮湿特性、阻燃表现及预期安装规则，外观本身不是证据。
Can two ‘MC4-compatible’ connectors from different brands be mated?两个不同品牌的“兼容 MC4”连接器可以直接混插吗？
Cross-mating is accepted only when the exact connector combination is authorized and supported by applicable certification, listing or engineering evidence. Similar appearance and nominal dimensions are insufficient.只有准确连接器组合获得授权，并有适用认证、列名或工程证据支持时才可接受混插；外观相似与名义尺寸相近并不充分。
What determines solar extension-cable length and conductor size?太阳能延长线的长度和截面积如何确定？
Use the complete positive and negative route, operating and fault current, ambient and grouping derating, connector limits, protection, allowable voltage drop, mechanical route and applicable installation rules. A catalog current number alone is not enough.需要结合正负极完整路径、工作及故障电流、环境与成束降额、连接器限值、保护、允许压降、机械走线和适用安装规则，不能只看目录中的单一电流数字。
