The Lighting Shield is able to see and protect between every line within your home. The connection between each line is called a mode. Unlike many surge protection devices, the Lightning Shield is able to protect from over voltage between every combination of lines.

Why is Generator Protection Critical?

What would happen if your generator were hit by lightning? When you purchase a generator, you feel secure knowing that your family won’t be left sitting in the dark when a storm wipes out the power and of course it’s a smart decision to protect your home with surge protection. But what about your generator? That’s where we come in. Our devices will protect your home and generator from the costly damage lightning can inflict on your electrical systems. Never worry about being left in the dark again when you have Lightning Shield in your home’s breaker panel and on your Generator. Lightning Shield is the only surge protector on the market that guarantees 100% lightning protection. We are so confident in our products that we back each unit with a $25,000 insurance policy.

LED Light Status Indication

Each of our Lightning Shields come with a LED Light Indicator, so you have the peace of mind that the Lightning Shield is actively working and ready to protect your home. The LED Light on this model is conveniently located on the Lightning Shield itself, making it easy to check if the LED lights are both still on. Each leg of electricity receives its own LED light indicator, so you can rest easy knowing that both legs of your home are always protected.

Next Level Protection & Peace of Mind

The Lightning Shield generator model’s purpose is to make sure that, when the lights go out, your emergency power systems are protected. We understand how important the functionality of your generator is and provide peace of mind to our customers by offering lightning protection backed by a 10 year warranty. Our revolutionary technology activates its protection in pico seconds (trillionths of a second) and can withstand over 228,000 amps!
