FAQ

Here you can find some of your common questions related to 1000V DC Isolator Switch, which can help answer your doubts.

How deep are your OEM/ODM service options for the 1000V DC isolator switch?

LETOP OEM/ODM service is a complete partnership designed to build your brand's unique product line. Not only do we offer high-quality logo printing and custom packaging, we also offer deep customization for your 1000V DC isolator switch. This includes custom Pantone color matching for the enclosure to match your brand VI, modifications to the mounting mechanism, selection of terminal specific types, and even adjustments to electrical parameters within the scope of IEC 60947-3 standards. We help you develop an isolator with unique competitive advantages by outsourcing R&D and manufacturing.

What is the Minimum Order Quantity (MOQ) for standard orders versus custom OEM projects?

We offer flexible MOQs to support our partners. For the standard 1000V DC isolator switch models (with neutral packaging), the MOQ is typically 200 units. For OEM projects, the MOQ starts at 500 units for basic customizations like branding. For more complex ODM projects involving mold modifications, the MOQ will be discussed on a case-by-case basis. Our goal is to foster long-term partnerships and grow with you.

How do your certifications (TÜV, CE, UL) concretely benefit my business in international markets?

Our certifications are your passport to global markets, saving you significant time and money. Holding TÜV and CE certifications for our 1000V DC disconnect switch means you can immediately and legally sell these products across the European Union. UL listing opens the door to the North American market, and SAA to Australia. By partnering with us, you bypass the lengthy and expensive process of certifying products from scratch. You can confidently bid on international projects and assure your customers that the components you supply meet the highest global safety standards, directly enhancing your brand's credibility.

How do you guarantee the quality and consistency of each 1000V DC disconnect switch in a mass production order?

Our manufacturing philosophy is based on quality. We have a strict ISO 9001:2015 certified quality management system in place. Every 1000V DC switch disconnect undergoes multiple checkpoints on our automated assembly line. This includes 100% functional testing (continuity and insulation resistance) and batch testing for mechanical endurance, IP rating, and arc extinguishing performance in our in-house lab. All the key parts are fully traceable, so every unit you get is exactly the same as the approved sample.

What makes your 1000V DC isolator safer and more reliable than other on the market?

Our main advantage is our arc extinguishing chamber. It can totally shut down the DC arc in under 3 milliseconds, which is way faster than the IEC 60947-3 standard and makes it way safer for operators during emergency shutdowns. We use high-quality, UV-resistant, and UL94V-0 flame-retardant materials for the enclosure and internal components. This ensures long-term reliability and performance in harsh solar PV systems environments, reducing after-sales service costs and protecting your reputation.

What kind of marketing and technical support do you provide to your distributors and brand partners?

Our success as partners is our own success. Our comprehensive support package includes high-resolution product images and videos, detailed technical datasheets, installation manuals, and editable marketing brochures. Our technical team offers online training sessions on the features and applications of our PV isolator switch 1000V. For key partners, we can also discuss joint participation in local trade shows and provide co-branded marketing materials to help you penetrate your market.

What's your typical lead time, and how do you keep supply chain stability for your partners?

For standard orders, our typical lead time is 2-4 weeks. The first order for OEM projects might take 4-6 weeks after sample approval. We keep our supply chain in check by keeping a safe stock of crucial raw materials, diversifying our supplier base for key components, and using an efficient production planning system. As your 1000V DC isolator switch manufacturer, we provide transparent production schedules and proactive communication to help you manage your inventory and project timelines effectively.

How do we get samples for testing and technical evaluation?

We want our potential partners to validate our quality firsthand. It's super easy: just contact our sales team with your company details and project requirements. Our standard 1000V DC isolator switch is free for qualified B2B partners. If you need custom OEM samples, we 'll give you a detailed quote and timeline for prototyping after we've had a technical discussion. We 're aiming to send out standard samples within 7 days.

What are your warranty terms and how do you handle potential after-sales issues?

We stand behind our products 100%. All of our 1000V DC isolator switches come with a standard 2 years manufacturer warranty against defects in materials and workmanship. If there's a problem with our product, we have a quick and easy after-sales process. You will be assigned a dedicated technical support contact. We will work with you to quickly diagnose the issue, and if a manufacturing defect , we 'll replace it and cover the associated shipping costs. We promise to resolve any issues with minimal disruption to your business.

As an installer or system integrator, can I purchase directly from you?

Our primary focus is on OEM and distribution partnerships, but we support large-scale installers and system integrators for project-based procurement. The key benefit of buying directly from a 1000V DC isolator switch manufacturer like us is getting factory-direct pricing for bulk orders, which can make your project more profitable. You also get access to our engineering team for technical support, so you can make the best product choices and integrate them perfectly.
