By answering these simple questions, we can recommend a product for you in just a few moments. This calculator helps us identify how much power your AC appliances use in your
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.
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.
For example: If you're running a 1500W inverter on your 12v battery with 1000 watts of total AC load. So your inverter will be consuming 83 amps (amps = watts/battery volts) from the battery for which you'll need a very thick cable. using a thin cable in this scenario can damage the inverter or you'll not be able to run your load.
The formula is based on a standard 12V battery: What is an inverter load calculation? Inverter load calculation is the process of estimating the total power (in Watts) consumed by all appliances you plan to connect to your inverter. This helps you choose an inverter and battery with sufficient capacity to power your home during an outage.
