Terms of Use
Effective date: July 6, 2026. These terms govern your use of offgridauthority.com ("the Site"). By using the Site you agree to them.
1. Informational Content Only
Off Grid Authority publishes reference material, guides, and calculators about off-grid power, home electrical capacity, storm preparedness, and related topics. All content is provided for general informational purposes only. It is not engineering, electrical, legal, financial, or safety advice, and it does not create a professional relationship of any kind.
2. Calculators and Tools
The Site's calculators (including the solar system, wire size, battery bank, load, panel capacity, and safe room tools) produce estimates from the numbers and files you provide, using stated methods and public standards (for example NEC 220.87 or FEMA P-320). Results are calculations, not approvals or determinations. Electrical work, structural work, and storm-shelter construction are regulated activities: final decisions belong to licensed professionals and your local authority having jurisdiction (AHJ). Never rely on a Site tool as the sole basis for a safety-related decision.
Files you load into Site tools (such as utility interval-data exports) are processed in your browser and are not transmitted to our servers unless a feature explicitly says otherwise.
3. Codes and Standards
References to the National Electrical Code (NEC), FEMA publications, ICC standards, and similar documents are paraphrases and summaries for education. The governing text is always the official publication as adopted in your jurisdiction, which may differ by edition and local amendment.
4. Affiliate Relationships and Advertising
The Site participates in affiliate programs, including the Amazon Services LLC Associates Program, and may display advertising. If you buy through an affiliate link we may earn a commission at no additional cost to you. Affiliate relationships do not change our published numbers or recommendations. See our Affiliate Disclosure.
5. Intellectual Property
Site content is © Off Grid Authority except where noted. U.S. government works referenced or indexed by the Site (such as FEMA P-320) are public domain and remain available from their official sources. You may link to and quote the Site with attribution; you may not republish substantial portions commercially without permission.
6. Acceptable Use
- Don't use the Site to violate any law or regulation.
- Don't attempt to disrupt, overload, or probe the Site's infrastructure.
- Don't scrape at volumes that degrade service for others.
7. No Warranty; Limitation of Liability
The Site is provided "as is" and "as available," without warranties of any kind, express or implied, including accuracy, fitness for a particular purpose, and non-infringement. To the maximum extent permitted by law, Off Grid Authority and its operators are not liable for any direct, indirect, incidental, consequential, or special damages arising from your use of the Site or reliance on its content or tools, even if advised of the possibility of such damages. Some jurisdictions do not allow certain limitations, so parts of this section may not apply to you.
8. Third-Party Links
Links to third-party sites (retailers, government resources, manufacturers) are provided for convenience. We don't control and aren't responsible for their content, availability, or practices.
9. Privacy
Our handling of analytics data and email addresses you submit is described in the Privacy Policy.
10. Changes
