FAQ's


1. What is a DC surge protection device (SPD) and how does it work?
A DC surge protection device (SPD) is designed to protect power circuits from voltage spikes. It works by diverting excessive surge energy—like those caused by lightning or switching operations—away from sensitive components, especially in photovoltaic systems and inverters.
2. Where can I buy a reliable DC surge protection device in Australia?
You can purchase high-quality DC surge protection devices from Fastron Electronics. We stock a wide range of approved products suitable for inverters and PV systems, backed by technical support and fast shipping across Australia.
3. What is the difference between a DC SPD and an AC SPD?
The key difference lies in the type of current each device is designed to protect. A DC SPD protects direct current systems like solar installations, while an AC SPD is used in alternating current circuits typically found in residential or commercial power grids.
4. How does a solar SPD protect solar power systems from voltage spikes?
A solar SPD shields your photovoltaic system by diverting harmful surge currents caused by lightning or grid disturbances. This prevents damage to sensitive components such as inverters and ensures the system’s reliability and longevity.
5. Can I use a DC surge protection device in my solar power installation?
Yes, DC surge protection devices are specifically designed for use in solar power installations. They help protect inverters and other PV system components from unexpected voltage surges.
6. What are the applications of solar SPDs in photovoltaic (PV) systems?
Solar SPDs are used in photovoltaic systems to safeguard equipment like inverters, panels, and control systems from transient overvoltages. They’re crucial for maintaining the efficiency and safety of solar power systems.
7. How do I install a DC surge protection device in a solar power system?
DC surge protection devices are typically installed near the inverter or where the DC wiring enters the building. Proper installation should follow safety standards and may require professional assistance for best results.
8. What voltage ratings are available for DC surge protection devices?
Fastron Electronics offers DC surge protection devices in various voltage ratings suitable for different PV system sizes. These are available in Type 1 and Type 2 classes with CE, UL, CB, and TUV approvals.
9. What is the typical lifespan of a solar SPD?
The lifespan of a solar SPD depends on the frequency and intensity of surges. High-quality SPDs from brands like Raycap or THOR, available at Fastron Electronics, are built to offer long-term protection with proper use.
10. How do surge protection devices improve the safety and longevity of electrical systems?
Surge protection devices safeguard electrical systems by diverting dangerous overvoltages. This reduces the risk of equipment failure, data loss, and fire hazards—extending the life of electrical components and improving overall system reliability.
11. Are DC surge protection devices suitable for high-voltage solar installations?
Yes, DC surge protection devices offered by Fastron Electronics are suitable for high-voltage solar installations. They’re designed to meet rigorous safety and performance standards required in industrial and utility-grade solar systems.
12. Can a solar SPD be used for both residential and commercial solar systems?
Absolutely. Solar SPDs are versatile and can be used in both residential and commercial PV systems to protect against surges and ensure long-term system performance and safety.
13. Are your DC surge protection devices compliant with Australian electrical standards?
Yes, our DC surge protection devices meet international certifications such as CE, UL, CB, and TUV, which align with Australian electrical standards for safety and reliability.
14. What are the benefits of using a DC SPD in protecting sensitive solar equipment?
Using a DC SPD helps protect sensitive solar equipment like inverters and controllers from transient voltages, ensuring consistent performance, reducing downtime, and preventing costly damage to your PV system.
15. Do solar SPDs offer protection against both lightning strikes and electrical surges?
Yes, solar SPDs provide robust protection against both lightning-induced surges and other electrical disturbances. They are an essential part of safeguarding your photovoltaic system from unexpected power events.
