Finding a high capacity backup power supply or an inverter that can handle all of your power-hungry electronics can be quite a task. But if you’re wanting to run appliances and other electric devices that have a high power demand, a 12000 watt power inverter might just be the kind you want.
Inverters rated at this capacity can run pretty much everything you’d want, from kitchen appliances to laundry appliances – and even your power tools.
12000 watt power inverters can pretty much run multiple of these high-power appliances at once as well, which is great when you need a backup power supply. If you are looking to use this inverter with a solar power source, it is perfect for that too.
To help you choose which inverter is the best for you, we’ve put together a comprehensive list below.

What can a 12000 watt inverter run?
Choosing the correct model of power inverter is quite important because you want one that will satisfy all your power needs. If you want to run multiple heavy-duty and power-hungry appliances, then a 12000 watt power inverter is definitely the kind you want.
12000W is on the higher side of power capacity as far as inverters go, which means that you can run multiple refrigerators, multiple power tools, and multiple other kitchen appliances if you wish. Naturally, you can also power lighting, computers, or even air conditioners.
As long as whatever you are trying to run does not go over the total capacity of the inverter, you can pretty much power everything you need. So if you want to run lights and kitchen appliances (fridge, coffee machine, microwave, maybe even stoves), you can.
It is important to note, however, that you should check the wattage of whatever you are trying to plug into the inverter beforehand. It’s important not to overload the power inverter, and so you want to make sure that the total wattage of the appliances you are using will not go over the inverter’s capacity. Appliance manufacturers put this information on their products’ labels, to make the information easier to find.
When you purchase an inverter, a rule of thumb that you should keep in mind is that you want to buy an inverter rated at 15-20% more than the capacity that you actually want. So if you want to run appliances that have a total of 9600-10200 watts, then the 12000W inverter is perfect. If you want to run more than this, you may want to look into higher capacities, as 9600~10200 is what a 12000W inverter will comfortably run.
Can I run commercial appliances with a 12000W power inverter?
A 12000 watt power inverter is definitely capable of running bigger/commercial appliances. These appliances often need about 1500-2500W (each) to run, but there are some that require even more power. However as long as the total of all the units don’t exceed 10200W, your 12000W power inverter will run all of them comfortably.
How many amps does a 12000 watt inverter draw?
The formula to get the amperage of a power inverter is as follows:
Amperage = Watt / Volts
As such, a 12000W power inverter has roughly the following amperage:
12000/110V = 109.09 Amperes

SUNGOLDPOWER 12000W Power Inverter - Pure Sine Wave
This 12000 watt power inverter is one of the best available on the market today. Not only is it a pure sine wave (more efficient than modified wave) inverter, it is also an MPPT solar charger, an AC charger, and even an auto-transfer switch all rolled into one.
This inverter is low frequency and is AC priority (by default), meaning when there is AC input, the battery will charge first before the inverter transfers the input to power the load. You can choose battery priority so that the inverter will use the battery before the AC input.
The SUNGOLDPOWER inverter is loaded with features such as: smart remote control, solar panel support w/ MPPT function, AGS (Automatic Generator Starting), four-step intelligent/smart battery charging, and more.
The Sungoldpower inverter is reasonably priced for such a large capacity power inverter. It does, however, cost slightly less than the other inverters we have listed here.
With a surge rating of 36000W, various special features, a display LED to let you know the status of your power load and inverter, cooling fans, and aluminum housing, the Sungoldpower 12000W inverter is likely one of the best on the market today. With it being slightly cheaper than the others on this list, we give it 5 stars for having the more bang for the buck.
