Frequently Asked Questions

Get answers to common questions about surge protection.

Do You Need a Surge Protector?

Absolutely. A $30 surge protector can save your $50,000 inverter. Real-world data shows that top EPCs now require hybrid SPDs on every solar site to prevent costly downtime and equipment damage.

What Does a Surge Protector Look Like?

Our LKX-PV40 model is a compact 800V DC surge protector designed for solar systems. It features quick-connect terminals, status indicators, and a robust housing for outdoor use.

Are Surge Protection Devices Mandatory?

While not always legally required, SPDs are strongly recommended by insurers and system integrators. They prevent costly damage from electrical surges, extend equipment life, and offer a fast ROI by minimizing downtime.

Can You Customize SPDs for Our Brand?

Yes. We offer full OEM and ODM services, including custom labeling, packaging, and technical modifications to meet your specifications.
