Next-Generation EMP Protection with Military-Certified Testing
Approved by the Department of Homeland Security
Whole Home Generator EMP Shielding & Lightning Protection (SP-120-240-G) by EMP Shield
Protect your investment and ensure your entire home is secure at all times! With EMP Shield, you can trust that all electronics and equipment connected to your electrical system will withstand lightning strikes, solar flares (coronal mass ejections), power surges, and electromagnetic pulses.
Electromagnetic Pulses (EMPs) pose a significant threat due to the intense electrical loads that can induce heat in conductors, leading to potential damage. All EMP Shield products undergo rigorous testing at the Keystone Compliance Facility. Because recreating an EMP surge requires a substantial amount of electricity, only a few facilities can perform these tests.
The Keystone Compliance Facility is a federally approved lab that conducts some of the most advanced and precise technological assessments available today. Every test and evaluation at this facility is thoroughly documented to demonstrate the true capabilities and durability of the EMP Shield.

How Does an EMP Shield Work?
The EMP Shield protects your electronic devices by shunting or shorting excess voltage that comes from the grid or is induced within your home. Whether the electrical surge originates inside your house or from an external source, the EMP Shield detects it and promptly activates to safeguard your electrical system.
Thanks to modern technology like SightSpeed™, integrated into the EMP Shield, it can react in under one billionth of a second! This rapid response means that the overvoltage is redirected away from your devices before it can rise to damaging levels.

Why You Need an EMP Shield
In 2019, an Executive Order was signed to enhance national resilience against electromagnetic pulses, urging individuals to take protective measures. With an EMP Shield, your home can remain operational even if the grid fails due to damage to technology or infrastructure.
Having an EMP Shield gives you an advantage, as it ensures that your vehicle will function after an EMP event, helping you return home safely or obtain necessary supplies. Additionally, if lightning strikes your home, you won’t face hefty repair costs for your appliances and devices.
An EMP Shield also guarantees that your solar system or generator will continue to operate, even in the face of EMP threats or attacks.
