EMP Defender installed in solar generator

Helps protect from EMP bursts

Includes: mini EMP defender shield, installed at RevoPower factory.

This device is rated to protect against EMP, ESD, and CME damage. The EMP Defender works like a flood control gate on a lake. On a lake once the water level reaches a maximum level the extra water is diverted and the lake level is maintained at a safe level. The EMP Defender works like this by shunting the extra voltage away from your electrical circuit allowing it to operate as normal.
