DC Lightning Surge Arrester

What is a DC Lightning Surge Arrester?

A DC Lightning Surge Arrester is a critical device used to protect DC-side equipment within solar power generation systems from damage caused by lightning strikes and overvoltage events. By rapidly discharging transient, high-energy pulses, it ensures the safe and stable operation of PV modules, inverters, and other sensitive electrical equipment.

At its core, the device utilizes high-quality Metal Oxide Varistors (MOVs), offering low residual voltage, high surge current capacity, and a surge impact lifespan of up to 100,000 cycles. It is designed to withstand extreme environmental conditions ranging from -40°C to +85°C. The modular design supports hot-swappable replacement and integrates intelligent alarm functions, allowing for real-time operational status monitoring and data transmission via an RS485 interface—making it ideal for the remote operation and maintenance of unmanned power stations.

Sample Delivery Lead Time

Samples are prepared and shipped within 15 business days; this timeframe can be expedited to 7 business days depending on specific order requirements. The lead time for bulk purchase orders is 30 days. We offer OEM customization services and provide a full suite of test reports and international certification documents.

Damage Risk Control Measures

We employ thickened, shock-resistant packaging materials, mark outer cartons with "Fragile" labels, and individually package each unit with built-in cushioning and support structures;

Throughout the entire shipping process, we utilize a third-party logistics monitoring system to track temperature, humidity, and vibration data in real-time;

Each shipment includes a damage inspection record card upon arrival to ensure the integrity of the delivery.

We offer global warranty support and provide multilingual installation guides and technical documentation, ensuring compliance with major international standards such as IEC and UL;

Prior to leaving the factory, every DC Lightning Surge Arrester undergoes 100% comprehensive testing to guarantee stable operation under complex conditions, including high altitudes, high humidity, and salt-mist environments.

Core Advantages & Key Selling Points

Response time of less than 25 nanoseconds, effectively suppressing lightning-induced overvoltages and minimizing the risk of equipment damage;

Features an IP67 protection rating (waterproof and dustproof), making it suitable for a wide range of harsh outdoor environments;

Compact size and easy installation save valuable space within distribution cabinets, making it particularly well-suited for high-density photovoltaic array layouts. Supports a multi-stage cascaded protection design, enabling system-level overvoltage coordination and enhancing overall electromagnetic compatibility;

Features a built-in thermal disconnect mechanism that automatically interrupts the circuit upon the device's end-of-life, thereby eliminating potential fire hazards.

The DC Lightning Surge Arrestermade in China holds TUV, CE, and RoHS certifications and complies with the requirements of the ISO 9001 quality management system. It has operated stably for over five years across more than 30 countries and regions worldwide, serving a client base that includes leading PV EPC contractors and power utility operators.
