How do I select an inverter that has enough power?

To select an inverter from DonRowe.com that has enough power for your application, add the watts for items you may want to run at the same time. Use the total wattage, plus 20%, as your minimum power requirement. Note: The wattage's given below are estimates. The actual wattage required for your appliances may differ from those listed.

How much wattage does an inverter need?

Check the nameplate on the appliance to determine the actual wattage required. * Appliances and tools with induction motors (marked * in tables) 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.

How do I know if my inverter is bigger than 825w?

To find out your size, you just need to add together the total wattage of the appliances you wish to run. For example, TV (60W), coffee maker (700W), lamp (60W), phone (5W). So add together 60 + 700 + 60 + 5 = 825W. Now we know the inverter must be larger than 825W.

Do I need an inverter size chart?

The need for an inverter size chart first became apparent when researching our DIY solar generator build. Solar generators range in size from small generators for short camping trips to large off-grid power systems for a boat or house. Consequently, inverter sizes vary greatly.

Which Inverter should I Choose?

Pumps, compressors and air conditioners are the most common example and another common one is freezers and refrigerators (compressors). You want to select an inverter with a continuous rating that will handle the surge rating of your appliance so you don’t prematurely burn out the inverter.

Should I use an inverter with a larger capacity?

It’s important to always use an inverter with a larger capacity than your required power. This is because they are not completely efficient as they lose energy during the DC to AC conversion, plus require energy for internal systems. Often inverters are between 85% and 95% efficient. So you should factor this into your final number.
