Frequently Asked Questions (FAQ)

What is the advantage of using a 1500VDC Surge Protective Device?
As solar installations move to higher voltages to reduce wiring costs and improve efficiency, 1500VDC SPDs are essential to protect the inverters and DC infrastructure from lightning and switching surges.
Does Shuorui offer OEM/ODM services?
Yes, we specialize in OEM/ODM for global distributors. Our R&D team in Liushi can customize current ratings, trip curves, and enclosure colors to match your brand requirements.
How does the automatic reset function work in voltage protectors?
Our device monitors the voltage in real-time. If it detects a surge or drop beyond safety limits, it cuts the circuit. After the voltage returns to normal for a set delay time, the device automatically reconnects the power.
What standards do your products comply with?
All our products are manufactured according to IEC standards and have obtained CE, RoHS, and various other international certifications to ensure safety and quality in diverse markets.
