June 2025 Deadline — 70% EMP Shield

EMP Shield has undergone rigorous testing at the Keystone compliance facility. The Keystone compliance facility is a federally approved testing facility for conducting many of today ’s most advanced and rigorous technical tests. External testing and evaluation of the facility were thoroughly documented to show the true ability and durability of electromagnetic pulse shielding. Whether the electronic source comes from inside your home or enters your power system from outside the home (grid), the shielding layer will see the surge and protect your power system. EMP Shield 's technology responds in less than one billionth of a second. Since the shunt is completed very quickly, the overvoltage will be discharged from the equipment before the voltage rises enough to damage any equipment.
