1500V DC Surge Protectors are designed for high-voltage DC systems, especially in photovoltaic (PV) power plants and large-scale energy storage applications. They protect critical equipment from transient overvoltages caused by lightning strikes, switching operations, and grid disturbances.
They are mainly used in solar PV arrays, combiner boxes, inverters, battery energy storage systems (BESS), and industrial DC distribution networks. The 1500V DC system has become the global standard for utility-scale solar projects, where long cable runs, outdoor installations, and high exposure to lightning increase surge risks.
1500V DC Surge Protectors are typically DIN-rail mounted or panel-mounted, offering compact structure, high reliability, and fast response under extreme surge conditions.
Key parameters include a maximum continuous operating voltage (Uc) of up to 1500V DC, high nominal discharge current (In), and maximum discharge current (Imax) capability. These devices are designed in accordance with IEC 61643-31 for photovoltaic surge protective devices, ensuring safe operation in DC-only environments.
Our 1500V DC SPD series is designed with the features you need for fast, reliable installation and maintenance.
Unprotected PV systems are highly vulnerable to lightning strikes and overvoltage events, which can lead to costly damage and downtime. With compliance to IEC 61643-31 standards, our 1500V DC SPDs effectively mitigate these risks. We manufacture millions of DC SPDs every year, helping businesses protect their critical equipment and ensure long-term system reliability.
Our 1500V DC Surge Protection Devices (SPDs) provide up to 99.99% protection against transient overvoltages, ensuring the highest level of safety for your DC infrastructure.
Engineered for utility-scale solar energy systems and commercial PV plants, these SPDs combine advanced MOV technology with robust metal and plastic housings to deliver comprehensive protection for sensitive equipment.
1500V DC Surge Protective Devices are crucial for large-scale solar farms because they safeguard long strings of PV panels and central inverters from high-voltage surges. Without proper protection, lightning events and switching transients can cause irreversible damage, leading to significant financial losses and system downtime.
Yes, 1500V DC SPDs are installed in parallel with the DC system, while a 1500V DC fuse or DCB is connected in series upstream. This ensures that if the SPD fails, the circuit is safely disconnected, protecting the PV system and sensitive equipment.
