Surge protection devices for solar PV are crucial to shield sensitive components from lightning and power surges, ensuring system longevity and reliability.
Solar panels and related equipment are often installed in large open areas, making them particularly vulnerable to direct and indirect lightning.
Frequent lightning strikes can damage the system, causing significant downtime for solar farms and high maintenance costs.
SPDs protect these components by diverting surge currents to the ground, preventing potential damage and ensuring the normal operation of solar farms.
Where and What Type of Surge Protectors to Install in Solar Farms
By choosing the right surge protector, especially for dedicated solar surge protection, and installing it correctly, our SPD will best protect your solar farm investment.
Installation Location & Recommended Solar SPD Types
Install a DC SPD between the PV module and the inverter.
Install an AC SPD between the AC output of the inverter and the main distribution cabinet.
Install an SPD in the main distribution cabinet as a central protection point for the distribution system.
Install an SPD in the grounding system to ensure that surge currents are effectively directed to the ground.
Install an SPD at the input and output of the data communication line to protect data and monitoring equipment.
DC SPD: Select an SPD suitable for the voltage level of the PV system, such as an SPD suitable for 600V, 1000V or 1500V DC systems.
AC SPD: Select an SPD suitable for household voltage levels (such as 230V or 400V), usually Type 2 or Type 3 SPD, for medium and low energy surge protection.
