One time you've identified the watt consumption per device, you'll need to calculate total kWh for each device by taking the hourly watt consumption multiplied past total hours of use. For case, if a device uses 300 watts per hour and you run it for 5 hours a day, multiplying both numbers volition requite you 1500 watt-hours or 1.5 kWh per day consumption. You'll need to calculate daily consumption for each device yous want to power to become the total daily wattage consumption amount you'll need to cover.

Method 2 – Amp calculation

If you lot don't run into any label or tin can't go the data listed to a higher place, look at the amps rating on the device. This rating should show how many amps your device consumes.

Next, multiply the amp-count and voltage to become the watts. For a default, the standard output voltage for nearly countries is 120V. As an example, if your device has a label with vi.v amps and 120 volts, you'll multiple 6.5 past 120 to summate that the device consumes 780 watts per hour.

Method 3 – Ability Meter

Use a power meter. Connect the meter to your device, plug it in a wall outlet, and it will show yous the power consumption rating of the device. This will be an accurate way to know watt consumption, just is less efficient if you need to figure out consumption rates for many devices.
