I’ve added an inverter sizing calculator to my website WattBuild. The goal is to establish what devices will be used, and to calculate continuous and surge power requirements using typical loads from our device research.

Open to any feedback!

    Doesn’t a space heater’s requirements go down after getting the heating elements to temp?

      Since this is not a battery life calculator, the metric to track is the max continuous power draw. Even if the draw lowers after initial heating, the inverter must still be able to handle the initial ramp up.

        Even if that’s your intent, listing max continuous power draw at the same ramp up power draw is inaccurate and gives people misinformation.

        If your goal is simply to show the ability of the inverter to handle the max wattage you can throw at it, removing max continuous wattage is a smarter decision.

        You show your goal, but also you only need to worry about having one accurate metric.
