SPD?<\/summary>\n          <p>\n            A 1000V DC SPD is a surge protective device used on the DC side of photovoltaic systems designed around 1000V DC.\n            It helps discharge surge energy and reduce the risk of damage to PV inverters and DC electrical equipment.\n          <\/p>\n        <\/details>\n\n        <details>\n          <summary>Where should a 1000V DC SPD be installed?<\/summary>\n          <p>\n            It is commonly installed inside PV combiner boxes, solar DC distribution boxes, and near inverter DC inputs.\n            The exact position depends on the PV system design and protection concept.\n          <\/p>\n        <\/details>\n\n        <details>\n          <summary>Can I use a 1000V DC SPD in a 1500V PV system?<\/summary>\n          <p>\n            No. A 1000V DC SPD should not be used in a 1500V PV system. The SPD voltage rating must match the maximum DC voltage of the system.\n          <\/p>\n        <\/details>\n\n        <details>\n          <summary>Should I choose Type 2 or Type 1+2 1000V DC SPD?<\/summary>\n          <p>\n            Type 2 DC SPD is commonly used for PV DC-side protection. Type 1+2 DC SPD may be selected when the project has higher lightning exposure,\n            an external lightning protection system, or an impulse current requirement.\n          <\/p>\n        <\/details>\n\n        <details>\n          <summary>Is a 1000V DC SPD suitable for PV combiner boxes?<\/summary>\n          <p>\n            Yes. PV combiner boxes are one of the most common installation points for 1000V DC SPDs, especially before the DC circuit reaches the inverter.\n          <\/p>\n        <\/details>\n\n        <details>\n          <summary>Can AC SPDs be used for solar DC circuits?<\/summary>\n          <p>\n            No. Solar PV DC circuits require DC-rated SPDs.
