Critical Electrical Safety & Fire Hazard Warning

High-amperage direct current (DC) systems, large Lithium (LiFePO4) battery banks, and high-wattage AC power inverters carry inherent risks of severe electric shock, arc flash, thermal runaway, component explosion, and electrical fire.

All calculations, conductor AWG gauges, fuse ampacities, and solar recommendations generated by WattsToAh.com are provided strictly for preliminary planning, conceptual estimation, and educational purposes. You must verify all final schematics, cable lengths, and overcurrent protection with a licensed electrician, NABCEP certified solar professional, or ABYC certified marine technician.

1. Acceptance of Terms

By accessing or using WattsToAh.com ("the Website"), you agree to be bound by these Terms of Service. If you do not agree to these terms in full, do not use our calculators, widgets, or engineering reference guides.

2. No Professional Electrical Engineering Relationship

The content and calculation tools on WattsToAh.com do not constitute formal electrical engineering consulting, licensed contracting, or certified architectural design. Physical electrical installations require on-site assessment of ambient temperatures, conductor insulation ratings (e.g., 75°C vs 90°C vs 105°C), conduit fill derating, and local jurisdictional code compliance (NFPA 70 / NEC).

3. Absolute Limitation of Liability

To the maximum extent permitted by applicable law, WattsToAh.com, its owners, operators, developers, and affiliates shall not be liable for any direct, indirect, incidental, consequential, special, or exemplary damages, including but not limited to:

  • Property damage, vehicle damage, boat damage, or electrical fires resulting from undersized conductors, improper fusing, or battery installation errors.
  • Loss of battery capacity, BMS lockout, or equipment failure resulting from reliance on mathematical estimations.
  • Personal injury or death arising from the handling of electrical energy storage systems or high-voltage inverters.
