    <\/div>\n
    Core Features & Architecture<\/div>\n

    <\/p>\n

      \n
    • Modular Plug-In Design:<\/strong> The internal protective components utilize plug-in clips, making it easy to swap out degraded modules without rewiring the base.<\/span>\u00a0<\/li>\n
    • Visual Status Indicators:<\/strong> It features clear inspection windows. A Green<\/strong> window indicates normal operation, while a Red<\/strong> window warns that the module has failed and must be replaced.<\/span><\/li>\n
    • Integrated Safety Mechanisms:<\/strong> Equipped with an internal flash barrier to stop arc propagation and a combined disconnection\/short-circuiting device to eliminate fire hazards from DC arcs.<\/span><\/li>\n

      <\/ul>\n

      <\/div>\n
      Installation Best Practices<\/div>\n

      <\/p>\n

        \n
      • Voltage Cushion:<\/strong> For safety and long-term system stability, ensure that the open-circuit voltage (\\(U_{oc}\\)) of your solar string does not exceed roughly 830V DC<\/strong> (allowing the recommended 1.2\u00d7 safety factor below the SPD’s 1000V limit).<\/span><\/li>\n
      • Placement:<\/strong> It should be installed in a DC combiner box or a distribution enclosure between the solar panel array and the inverter.<\/span><\/li>\n
      • Safe Distances:<\/strong> Maintain at least a 10mm safety gap between the SPD module and any other grounded components inside the housing.<\/span><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
