Procurement & BOM Notes
How Type 1+2 Combined Protection | 40kA DC SPD | 1500V Solar PV Surge Arrester is sourced
OmniSol sources Type 1+2 Combined Protection | 40kA DC SPD | 1500V Solar PV Surge Arrester factory-direct as part of the Surge Protective Device family, quoted against your project quantity, destination port and product family id (OS-ETK-EKU5-T1PLUST2-40PV). Pricing and lead time are confirmed by SKU and order size at the RFQ stage, and OmniSol can propose a current-equivalent option if the exact variant is unavailable, so the line stays on schedule.
BOM fit
Type 1+2 Combined Protection | 40kA DC SPD | 1500V Solar PV Surge Arrester sits between the array and the inverter, so it is specified with the string count, system voltage and protection layout of the project. It ships consolidated with cable, connectors and the rest of the electrical BOS, under one QC report and one document set.
Certification check
Confirm the Type 1+2 Combined Protection | 40kA DC SPD | 1500V Solar PV Surge Arrester certificates — IEC, EN61643-31 — the breaking capacity and any market-specific listing before ordering. OmniSol supplies the datasheet, component brand list and inspection photos.
Product Overview
Combined Type 1+2 DC surge protection in a single device with 40kA discharge current and IP20 built-in rating for flush installation inside switchboards or combiner enclosures. One device satisfies both lightning (Type 1) and switching surge (Type 2) coordination requirements at a single installation point.
Combined devices simplify the BOM for installations where both protection classes are required, and ensure factory-matched Type 1 and Type 2 coordination without separate device selection.
Combined Type 1+2 devices protect against both direct and nearby lightning strikes from a single device, eliminating the need for separate Type 1 and Type 2 SPDs at the same installation point. Required at the service entrance of structures with an external lightning protection system per IEC 62305-4 coordination requirements.
Applications
PV string and array protection
Combiner box internal protection
Inverter DC input circuits
Utility and C&I solar BOS
Certifications & Compliance
Frequently Asked Questions
When is combined Type 1+2 preferred over separate devices?
A combined device is preferred when installation space is limited, when factory-matched coordination is required, or when the switchboard position must satisfy both Type 1 and Type 2 requirements simultaneously. Separate devices give more flexibility if the two protection classes need to be installed at different points.
Is Type 1+2 DC SPD required for all PV installations?
Type 1 is only required where the building or system has a direct lightning protection system (LPS), or where local code mandates it. For most PV systems without a direct LPS, Type 2 alone is sufficient. Confirm with the project electrical designer.
