Protect your solar and wind systems from EMP, solar flares, and lightning strikes. 

The EMP Shield is one of the world’s fastest whole home surge protectors operating in less than 1 billionth of a second. EMP Shield will protect all the electronics and equipment connected to your electrical system.

  • Incredibly Powerful - capable of withstanding up to 228,000 Amps per phase (E1, E2 and E3)
  • SightSpeed Technology - patented technology pulls excess electricity from your electrical system in 500-Trillionths of a second
  • IP 66 Weather Proof - can be used in extreme hot and cold climate conditions
  • Easy Install - Designed to install easily (within 10 minutes) for any application - installation guide included

EMP Shield will protect electronics and equipment relying on your solar and wind systems. This is accomplished by shunting (shorting) the over voltage coming in from the grid and the voltage surges that are collected within your home. Since the shunting is completed incredibly fast, the over voltage is drained away from the equipment before the voltage can rise high enough to damage any equipment.

The EMP Shield attaches to the device that immediately follows the combiner (or PV array). This will be an inverter or charge controller. Find the maximum input voltage for the device and select an EMP Shield that matches the optimal input voltage range into the device.

As an example: many off grid systems lead to charge controllers. If there are 2x charge controllers that each have a maximum input voltage of 150V you would need a dual 90-120V EMP Shield. If you have only 1x charge controller that has a maximum input voltage of 150V, you will need the single 90-120V EMP Shield. If you have an inverter as the first device that has a maximum input voltage of 60V you would select the 48V EMP Shield.
