Before we go any further, we highly recommend that you choose a pure sine wave inverter. This type of inverter delivers high-quality electricity, similar to your utility company. This way, none of your appliances run the risk of being damaged. Now, when it comes to sizing your inverter, you. .
We have summarized the appliances that inverters from 300W to 3000W can run depending on their rated maximum power. Note to our readers: Use the above formulato determine. Short Answer: The size you choose depends on the watts (or amps) of what you want to run (find the power consumption by referring to the specification plate on the appliance or tool). We recommend you buy a larger model than you think you'll need (at least 10% to 20% more than your largest load). [pdf]
