Quick Selection
Confirm voltage class, Type and wiring before quotation
Ucpv must be checked against the maximum DC voltage that can appear at the SPD terminals. For PV projects, corrected string Voc, minimum design temperature and inverter or combiner-box limits should be reviewed before final model approval.
01
Confirm the real maximum DC voltage
Do not choose only from a “600V / 1000V / 1500V” name. Check the actual DC circuit condition and, for PV, the corrected maximum string Voc.
02
Confirm Type 2 or Type 1+2
Type classification describes surge-current test capability. It does not replace Ucpv selection. The project lightning-protection concept determines which class is required.
03
Confirm 2P, 3P or D4 wiring
Match the SPD protection paths to the actual DC+, DC−, PE and cabinet wiring arrangement. Pole count is not the same thing as SPD Type.

Selection boundary: the table is buyer-level pre-selection, not a substitute for the project design. A higher-voltage SPD does not upgrade the inverter, fuse holder, isolator, cable, connector or cabinet to the same voltage class.
Type & Pole Selection
Do not use “Type” and “voltage” as interchangeable choices
A 1000V DC SPD can still be Type 2 or Type 1+2. First confirm Ucpv, then confirm the surge-current class and the wiring configuration required by the project.
For induced and switching surge protection
Type 2 products are commonly used where the protection concept calls for 8/20μs discharge-current performance without a Type 1 lightning-current requirement.
- Confirm Ucpv separately from the Type classification.
- Check In, Imax and Up against the project specification.
- Confirm the actual installation point and backup protection coordination.
Where lightning-current capability is required
Type 1+2 may be selected where the lightning protection design indicates that partial lightning current can enter the DC circuit or the project specification explicitly requires combined Type 1 and Type 2 performance.
- Review the listed Iimp 10/350μs value for the exact model.
- Do not choose Type 1+2 only because its printed rating looks “higher”.
- Match Type, Ucpv, poles and document scope together.
2PUse only when the product protection paths and cabinet wiring match the DC+ / DC− arrangement shown in the model wiring diagram.
3PThree-module designs require confirmation of the actual multi-line protection arrangement and protective-earth path.
D4 ConfigurationD4 is a specific product/wiring configuration. It should be confirmed from the project drawing rather than inferred only from pole count.
Before Quotation
Send six inputs and avoid the wrong DC SPD
For a fast B2B model review, the most useful inquiry is not “price for 1000V SPD”. Send the electrical condition and purchasing context so the exact model, Type, poles and document set can be checked together.

05Quantity / Buyer TypeSample, project BOM, distributor stock or OEM/private-label requirement.
06Required DocumentsDatasheet, wiring diagram and model-specific certificate/test-document review.
Testing & Evidence
Use test evidence to reduce purchasing risk
Equipment photos are supporting evidence, not a substitute for a model-specific datasheet, wiring diagram or certificate scope. The exact product and declared performance still need to be matched before approval.
Component validation
MOV and related component checks support control of the core protection elements before assembly and batch release.
Impulse performance review
Declared 8/20μs and 10/350μs performance should be checked against the exact Type and model being ordered.
Thermal safety review
Thermal behavior and disconnection performance are important when MOV elements age or experience abnormal electrical stress.
Certification and test-document availability depends on the exact model, voltage, SPD Type, pole structure and branding configuration. Submit the target specification for document confirmation.
OEM & Project Supply
Keep product identity and documents aligned before batch supply
For distributors, combiner-box manufacturers, EPC buyers and OEM brands, model approval should cover the electrical specification and the buyer-facing product identity as one set.
What can be reviewed before order
LEEYEE can review the requested DC SPD model together with the intended label, packaging and available technical documents before sample or batch approval.
- Voltage, Type, poles and installation position.
- Logo, label, model naming and packaging requirement.
- Datasheet, wiring information and available document scope.
- Expected quantity and project/OEM approval requirement.
Simple approval flow
Keep the workflow compact so procurement and engineering can verify the same configuration before release.

FAQ
DC SPD voltage and Type questions buyers ask before ordering
How do I choose between a 600V, 1000V and 1500V DC SPD?
Start with the real maximum DC voltage that can appear at the SPD terminals. 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.
Can I use a 1500V DC SPD in a 1000V system?
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.
What is the difference between Type 2 DC SPD and Type 1+2 DC SPD?
Type 2 is associated with 8/20μs discharge-current performance and is commonly used for induced or switching surges. Type 1+2 also includes lightning-current capability tested with a 10/350μs impulse for the declared model. Final selection follows the project lightning-protection concept.
Is a 1000V DC SPD always correct for a 1000V PV system?
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.
How should I choose 2P, 3P or D4?
Use the actual product wiring diagram and the project’s DC+, DC− and PE arrangement. Pole count and D4 configuration describe the protection arrangement; they are not substitutes for Ucpv or SPD Type selection.
Do CE, TÜV or CB documents cover every DC SPD shown?
Document availability and scope vary by exact model, voltage, Type, pole structure, manufacturer and branding configuration. Request the latest model-specific document set before formal project, tender or OEM use.
