Product Features

The BY08DC 1+2-12.5 series T1+T2 DC Surge Protective Device (SPD) is a high-performance solution designed to protect photovoltaic systems from both transient and surge voltages. This device is specifically engineered for use in string boxes and inverters, where it shields sensitive equipment from electrical disturbances that can occur due to lightning strikes, grid fluctuations, or other external surge events. Available in both 2P and 3P configurations, it is versatile for a wide range of applications.
The BY08DC 1+2-12.5 series SPD offers a voltage range of 500VDC, 1000VDC, and 1500VDC, making it suitable for various DC systems used in solar power installations. It combines the functions of both T1 and T2 protection, providing comprehensive defense against electrical surges and transients. T1 protection ensures that the device can withstand high-energy surges, such as those caused by direct lightning strikes, while T2 protection offers ongoing suppression of lower-level surges throughout the operation of the system.
This surge protector is equipped with high-energy Metal Oxide Varistor (MOV) technology, which allows it to absorb and dissipate surge energy effectively. The device is capable of handling discharge currents ranging from 20kA to 40kA, ensuring that it can manage even substantial surge events, protecting critical components in the photovoltaic system from permanent damage. The MOV technology enables rapid response to over-voltage conditions, preventing surges from reaching sensitive equipment.
The primary function of the BY08DC 1+2-12.5 series SPD is to divert excess electrical energy safely into the ground, thus ensuring that your inverter, string box, and other essential components remain undamaged and operate smoothly. The device ensures the protection of electrical systems, extends their lifespan, and enhances the overall reliability of the solar power installation.
