Faraday Architecture: Protecting Critical Electronics from CME, EMP & Grid Surge Events

Physics-backed shielding protocols for solar inverters, radios, cyberdecks, and corporate cold-backup vaults.

Primary A4 Action Checklist

  1. Understand E1, E2, and E3 electromagnetic pulse components vs Carrington-class solar Coronal Mass Ejections (GMD)
  2. Store spare transceivers, RTL-SDR dongles, and Project Alexandria NVMe drives disconnected inside >80dB Faraday enclosures
  3. Install Type 1+2 Surge Protection Devices (SPDs) at your UK consumer unit and DC solar combiner box
  4. Verify Faraday attenuation quarterly using an 868MHz LoRa or 2.4GHz Wi-Fi RSSI drop test

# OFF-GRID ACADEMY FIELD MANUAL 07 ## Faraday Architecture: Protecting Critical Electronics from CME, EMP & Grid Surge Events ### 1. Separating Physics from Prepper Folklore In the UK National Risk Register, **Severe Space Weather (Coronal Mass Ejection / Geomagnetic Disturbance)** is a high-consequence tier risk. A Carrington-class CME induces massive quasi-DC geomagnetically induced currents (GICs, the **E3 pulse**) in long transmission lines, saturating and overheating 400kV/275kV National Grid step-up transformers and sending destructive voltage transients into anything plugged into the mains. High-altitude nuclear EMP adds a nanosecond **E1 pulse** (20–50 kV/m) that couples into short antennas, ethernet cables, and unshielded silicon gates. ### 2. The Golden Rule of Galvanic Isolation A Faraday cage fails completely if **any conductive wire (USB cable, coax antenna lead, mains power cord)** penetrates the barrier. - Keep your **primary operational gear** on Type 1+2 SPD-protected circuits. - Keep your **Redundant Recovery Stack** (1x Quansheng UV-K5, 1x BritMesh 868MHz node, 1x RTL-SDR V4, 1x Project Alexandria 2TB NVMe, 1x folding MPPT controller) **completely unplugged** inside a double-nested conductive enclosure (`EOD-ENT-024`).
