Inverter Sizing Chart

When it comes to choosing an inverter, wattage is one of the key factors you need to take into account. Some devices, such as microwaves and refrigerators, can have high wattage surges when first turned on. To be on the safe side, it's advisable to add up the wattage of the largest devices you think you'll be using at the same time, and then allow yourself a 20% headroom. This will help ensure that you don't run into any problems down the line.

Note: The wattages given below are estimates. The actual wattage required by your appliance may differ from the listed wattage. To figure out how much power your devices use, check the wattage rating on the appliance. You can usually find this information on a label on the back or bottom of the appliance. This will give you a good estimate of how much power the inverter can handle.
