Disclaimer

Wattlyst calculators give estimates for planning. They are not an official electricity bill, a supplier quotation or an engineer's sign-off, and they do not replace a licensed electrician.

Estimates, not official figures

Bill estimates use the published tariff, taxes and charges as last checked on the page. Your actual bill can differ because of fuel price adjustments, quarterly adjustments, arrears, meter readings and charges set by your DISCO or K-Electric. Only your bill is official.

Electrical safety

Wire, cable, breaker, battery, UPS, generator, inverter and solar results are for planning and comparing options. Electrical work can cause fire, injury or death. Batteries can release explosive hydrogen gas while charging and can deliver very high short-circuit current, so keep them ventilated and fused. Always have wiring, breakers, earthing and solar installations designed, installed and checked by a licensed electrician, and follow local codes and the manufacturer's instructions.

Products and prices

Appliance wattages, battery capacities and prices are typical values from the sources shown on each page. Check the label or datasheet of your own product, and get written quotes before buying.

No warranty

We test our formulas carefully, but we cannot guarantee that every result is correct for your situation. You use the results at your own risk. See our terms of use.
