Planning estimates only

The Off-Grid Planner's calculators provide planning estimates based on the inputs you supply and the assumptions documented on How We Calculate. They are not a substitute for measuring your own equipment, reading manufacturer documentation, or seeking qualified professional advice for anything safety-critical.

Not electrical installation advice

This site does not provide instructions for mains electrical installation, high-voltage system modification, or bypassing electrical safety systems, and none of the calculators should be treated as such. Permanent caravan, RV, cabin or vehicle electrical installations — particularly anything involving 120V/230V/240V AC wiring — may be subject to local wiring standards and regulations, and may require a qualified, appropriately licensed electrician or auto-electrician depending on your jurisdiction. Always verify requirements with a qualified professional before undertaking any permanent electrical installation.

Verify appliance specifications yourself

Appliance wattage presets in this site's calculators are estimates based on commonly published figures, not measurements of your specific appliance. Actual consumption varies by brand, model, condition, ambient temperature and use pattern. Always check the rating label or manual of your actual appliance, or use a measured figure where possible, for the most accurate results.

No liability for decisions made using this site

While we aim for the calculations to be accurate and the methodology to be transparent, The Off-Grid Plannermakes no warranty as to the completeness, reliability or suitability of any calculator output, product recommendation, or written content for your specific circumstances. You are responsible for your own purchasing, installation and safety decisions.

Product and pricing information

Product specifications and prices are sourced from manufacturers and retailers at a point in time and may have changed. Always confirm current specifications and pricing directly with the retailer or manufacturer before purchasing.
