Whole Home Generator EMP Shielding & Lightning Protection (SP-120-240-G)

EMP Shield Generator Model (SP-120-240-G)

Protect your whole-home standby or backup generator (and the power it supplies) from the effects of a high-altitude nuclear electromagnetic pulse (EMP/HEMP — E1, E2, and E3 phases), coronal mass ejection (CME)/solar flare, and lightning. The generator model is designed for single-phase 120/240V generators (compatible with Generac and other generators that produce 120/240V AC).

Because a transfer switch isolates the generator from the home’s main panel when utility power is present, a dedicated protection point at the generator is recommended so the unit’s control electronics and electrical system remain protected. This helps ensure your backup power source is available when needed.

Independently tested by Keystone Compliance (a respected military and compliance testing laboratory) to MIL-STD-188-125-1 and additional military standards including MIL-STD-464C, MIL-STD-461G, and RS-105 (tested to 50 kV/m and 90 kV/m). Response time is extremely fast (begins shunting excess energy in less than 1 nanosecond), helping protect sensitive generator electronics before damaging voltages can build. It is also tested to high UL 1449 surge protection standards.

Key benefits include:

• Next-generation protection against EMP (all phases), CME/solar flare, lightning, and related power surges for the generator
• High current shunting capability to handle extreme energy events
• IP66 rated for extreme hot and cold outdoor conditions
• 100% lightning protection guarantee backed by a $25,000 insurance policy
• Industry-leading 10-year limited warranty (device replaced for $50 if it fails during the warranty period, no questions asked)
• Peace of mind that your backup power source stays functional during grid-affecting events so critical home systems can continue operating
