Power Inverter Selection Guide
Table of common tools and appliances and their power usage in Watts
Picking the right inverter is important, and we wanted to make it as easy as possible for you. SO to help you decide what power inverter you will need for your particular application(s) we have put together a comprehensive table of common tools and household appliances to give you an idea of how much power you will need to run them.
If you only want to run a single appliance then the recommended inverter Wattage is probably your best choice and you will just need to decide if you wanted a modifed wave power inverter or a pure sine wave power inverter.
If you want to run multiple appliances/tools at the same time then to select an inverter that will supply enough power for them simply add up the Watt's for all the items you may want to run. Once you have the total wattage, we suggest you add 20% to 30% to the total Watt's, and you have your minimum inverter power requirement.
Please Note: We have tried to be as accurate as we can but the wattages given in the table below are estimates only. The actual wattage required for these appliances may vary from those listed so these figures should only be used as a guide. We strognly recommend checking the appliance itself to determine the actual wattage required.
Any advice or recommendations are to be used as a guide only and we cannot be held liable if you decide to use this information. If you are not sure we recommend contacting the manufacturer of the device(s) in question or feel free to contact us and we will be more than happy to help you.
* Appliances and tools with induction motors (marked with * in the table) may require from 3 to 7 times the listed wattage when starting. The start-up load of the appliance or tool determines whether an inverter has the capability to power it. Be sure to check the specific wattage requirements and operating instructions for appliances / tools to be used. Please note: DC Amps listed in the table above is an estimate of the DC current draw from a 12V battery for that appliance. For 24V Inverters, the DC Amps from a 24V battery will be approximately half what is listed.
Power Conversion Formulas:
To help with working out your appliance's power, you can also use the following conversion formulas:
Watts ÷ 230 = Amps
Amps x 230 = Watts
