PV systems are exposed to lightning-induced surges, switching transients, long cable routes, and outdoor electrical stress. Proper SPD installation helps protect inverters, combiner boxes, monitoring equipment, and AC distribution systems.<\/p>\n      <\/details>\n\n      <details>\n        <summary>Where should SPDs be installed in a solar PV system?<\/summary>\n        <p>SPDs are commonly installed on the DC side near combiner boxes and inverters, and on the AC side near distribution panels. The final design depends on cable length, grounding, system voltage, and lightning exposure.<\/p>\n      <\/details>\n\n      <details>\n        <summary>What SPD is used in a solar inverter cabinet?<\/summary>\n        <p>A solar inverter cabinet may require DC-side SPDs at the inverter input and AC-side SPDs at the output or distribution side. The correct type depends on PV voltage, grounding system, cable length, and lightning exposure.<\/p>\n      <\/details>\n\n      <details>\n        <summary>How should SPDs be installed in a PV combiner box?<\/summary>\n        <p>In a PV combiner box, DC SPDs are typically installed close to the incoming string circuits and connected with short, direct grounding paths. Proper wiring length and grounding are critical for effective surge limitation.<\/p>\n      <\/details>\n\n      <details>\n        <summary>Do solar PV systems need both DC and AC surge protection?<\/summary>\n        <p>Many PV systems require protection on both sides. The DC side protects PV strings, combiner boxes, and inverter input. The AC side protects inverter output, AC panels, distribution boards, and grid-connected equipment.<\/p>\n      <\/details>\n\n      <details>\n        <summary>What is the difference between Type 1 and Type 2 solar SPD?<\/summary>\n        <p>Type 1 SPDs are used where direct lightning current risk must be considered. Type 2 SPDs are used for induced surges and switching transients. Many solar systems require coordinated protection depending on site risk and standards.<\/p>\n      <\/details>\n\n      <details>\n        <summary>When should Type 1 SPD be used in solar PV systems?<\/summary>\n        <p>Type 1 SPD is considered when the PV system is exposed to direct lightning risk, external lightning protection systems, high lightning density areas, or project specifications requiring lightning current discharge capability.<\/p>\n      <\/details>\n\n      <details>\n        <summary>Can lightning damage solar inverters?<\/summary>\n        <p>Yes. Even without a direct strike, induced surges can travel through DC strings, AC lines, communication lines, and grounding systems, damaging inverter electronics and causing system downtime.<\/p>\n      <\/details>\n\n      <details>\n        <summary>Why choose CNSPD for solar surge protection?<\/summary>\n        <p>CNSPD focuses on engineering-grade protection, factory-controlled production, OEM support, and long-term system reliability.
