Total Daily Consumption: 0.00 kWh
Estimated Peak Wattage (if you start every appliance at the same time): 0 W

Notice: This result gives you a maximum daily consumption. But think about it: Will you use your washer-dryer every day? Do you use your stove every day?

More importantly: More importantly, identify your high-consumption appliance to see if there is no other option (e.g., boiling water on your propane rather than your electric boiler).

Advice: Based on your estimated peak wattage, we recommend that you make sure your power system is sized to handle a little more than your peak demand. This extra margin can help account for unexpected surges and maintain reliable performance.
