☑ Peak = this appliance runs simultaneously with others. Sum of checked items = minimum inverter size.

Seasonal note: Off-grid loads often vary significantly by season (heating, cooling, lighting). Consider running this calculator for both summer and winter scenarios and use the higher value for system sizing.

Next steps: Use your daily Wh total in the Battery Bank Calculator and your monthly kWh in the Panel Sizing Calculator.
