Terms of Use & High-Voltage Electrical Safety Disclaimer | BackupWattGuide

⚠️ CRITICAL HIGH-VOLTAGE & ELECTRICAL HAZARD WARNING

Voltages greater than 50V DC or 120V/240V AC present severe risks of electrical shock, electrocution, arc flash explosions, and structure fires. Working inside electrical distribution panels, installing manual transfer switches, or creating series-wired high-voltage solar strings must strictly conform to the National Electrical Code (NFPA 70 / NEC) and local jurisdiction electrical ordinances. Always de-energize circuits and consult a licensed master or journeyman electrician before servicing or modifying premises wiring.

1. Educational & Mathematical Modeling Purpose Only

All content published on BackupWattGuide.com—including wire gauge calculators, battery runtime formulas, solar string sizing estimates, and inverter error code troubleshooting trees—is provided exclusively for informational, educational, and preliminary sizing purposes.

Because physical installations depend on real-world factors (such as ambient ambient attic temperature de-rating, conduit fill factors, terminal torque specifications, wire insulation thermal limits, and motor aging), published estimates must never substitute for on-site verification by qualified personnel.

2. No Electrician-Client or Professional Engineering Relationship

Accessing this website, reading guides, or utilizing the interactive calculators does not establish a professional engineering, electrical contractor, or advisory relationship between you and BackupWattGuide or its editorial contributors.

3. Limitation of Liability

Under no circumstances shall BackupWattGuide, its authors, editors, or operators be liable for any direct, indirect, incidental, consequential, or punitive damages resulting from:

Equipment damage (including blown inverter MOSFETs, thermal runaway in battery packs, or tripped branch circuit breakers).
Personal injury, electric shock, or property damage sustained while performing DIY electrical wiring or appliance modifications.
Discrepancies between calculated runtimes and real-world battery discharge performance during emergencies or utility blackouts.

4. Neutral-Ground Bonding and Transfer Switch Precautions

Portable power stations and off-grid inverters possess either floating neutral or bonded neutral architectures. Connecting a bonded-neutral portable power station directly to a home transfer switch that also has a bonded neutral in the main service panel creates a dangerous dual-ground loop violating NEC 250. It is your sole responsibility to confirm whether your inverter requires a floating neutral adapter or a switched neutral transfer switch.

5. Governing Law

These Terms of Use shall be governed and interpreted in accordance with the laws of the jurisdiction in which the site operator resides, without regard to conflict of law principles.
