1000V 2P DC Surge Protective Device — Professional Manufacturer for OEM/ODM & Wholesale Supply
The 1000V 2P DC surge protective device is designed for mid-to-high voltage photovoltaic systems, commercial solar installations, off-grid controllers, and DC power distribution panels that require stable and reliable protection against lightning surges and transient overvoltage. Built around a high-performance MOV (Metal Oxide Varistor) core, this model delivers fast response speed and strong energy absorption capacity tailored specifically for 1000V DC environments. As a direct manufacturer and OEM/ODM factory, we provide complete customization services and stable bulk supply for international distributors and solar project contractors.
The housing material of this model is made from PBT engineering plastic, selected for its excellent electrical insulation, dimensional stability, and resistance to thermal deformation. This makes the device durable in harsh outdoor conditions typically found in solar energy systems, including high temperatures, humidity, and constant UV exposure. The device is designed and manufactured in full compliance with IEC 61643-31:2018, the recognized international standard for DC surge protective devices. Additionally, the product carries CE certification and has passed TUV testing, ensuring dependable performance and credibility for global markets.
The 2-pole configuration is ideal for 1000V PV strings, string combiner boxes, DC distribution cabinets, hybrid inverter DC inputs, and energy-storage charging modules. Its integrated thermal disconnector offers reliable isolation of damaged MOV components in the event of sustained overvoltage conditions, ensuring that the protective function operates safely throughout its service life. A clear status indicator window allows installers or technicians to visually check the working condition at any time, making periodic inspection fast and convenient.
As a professional SPD manufacturer, supplier, and exporter, we support large-volume procurement and long-term supply programs for engineering contractors, PV system integrators, and wholesalers. OEM and ODM services include customer branding, label customization, parameter adjustment, special packaging, and technical documentation support. Our automated production lines and 100% routine testing environment help maintain consistent protection levels, low leakage current, and stable performance across all batches.
With its combination of certified safety, durable construction materials, and manufacturer-direct pricing, this model is an excellent choice for companies searching for reliable 1000V DC surge protection in bulk quantities. Whether for local distribution or large-scale photovoltaic EPC projects, our factory delivers consistent quality, fast delivery, and full technical support for global partners.
