Domestic/Off-grid Photovoltaic

Surge Protectors Essential for Photovoltaic Longevity

Diverting and absorbing surge energy: SPDs can quickly divert surge voltage to the ground, protecting downstream equipment from high-voltage spikes.

Rapid response: High-quality SPDs can respond to surges in nanoseconds, ensuring protection before the surge voltage reaches the equipment.

Multi-level protection: SPDs provide multi-level protection against various types and levels of surges, ensuring the safety of all parts of the system.

Where and What Type of Surge Protectors to Install in Domestic/Off-grid Photovoltaic Systems

By choosing the right type of surge protector and installing it in the right location, our SPD will do its best to protect your system.

Installation Location & Recommended SPD Types

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.

Once you’ve chosen the right DC and AC SPD for your system voltage, be sure to review their key technical specifications and follow proper installation and grounding practices to ensure maximum protection.
