For PV projects, review module Voc, modules in series and minimum design temperature, then confirm the selected Ucpv, Type and wiring configuration against the complete system design.<\/p><\/div><\/details>\r\n<details><summary>Can I use a 1500V DC SPD in a 1000V system?<\/summary><div class=\"dcvt-faq-answer\"><p>A 1500V SPD should not be used as a shortcut to solve a 1000V system design problem. The inverter, combiner box, isolator, fuse holder, cable, connector and protection coordination still need to match the actual system voltage class.<\/p><\/div><\/details>\r\n<details><summary>What is the difference between Type 2 DC SPD and Type 1+2 DC SPD?<\/summary><div class=\"dcvt-faq-answer\"><p>Type 2 is associated with 8\/20\u03bcs discharge-current performance and is commonly used for induced or switching surges. Type 1+2 also includes lightning-current capability tested with a 10\/350\u03bcs impulse for the declared model. Final selection follows the project lightning-protection concept.<\/p><\/div><\/details>\r\n<details><summary>Is a 1000V DC SPD always correct for a 1000V PV system?<\/summary><div class=\"dcvt-faq-answer\"><p>Not automatically. The corrected maximum PV string Voc and inverter or combiner-box voltage limits should be checked first. If the system design approaches or exceeds its voltage limit, changing only the SPD does not correct the rest of the DC system.<\/p><\/div><\/details>\r\n<details><summary>How should I choose 2P, 3P or D4?<\/summary><div class=\"dcvt-faq-answer\"><p>Use the actual product wiring diagram and the project\u2019s DC+, DC\u2212 and PE arrangement. Pole count and D4 configuration describe the protection arrangement; they are not substitutes for Ucpv or SPD Type selection.<\/p><\/div><\/details>\r\n<details><summary>Do CE, T\u00dcV or CB documents cover every DC SPD shown?<\/summary><div class=\"dcvt-faq-answer\"><p>Document availability and scope vary by exact model, voltage, Type, pole structure, manufacturer and branding configuration.
