Best 12000 Watt Power Inverter Reviews

Finding a high-capacity backup power supply or inverter that can handle all your power-hungry electronics can be a daunting task. But if you want to use appliances and other electrical appliances with a high energy requirement, a 12000 watt inverter may be the type you are looking for.

Inverters of this capacity can power almost everything from kitchen appliances to laundry appliances and even your power tools.

The 12000 watt inverters can also run multiple of these powerful devices at once, which is great when a backup power supply is needed. If you want to use this inverter with a solar energy source, it’s perfect for that too.

To help you choose which investor is best for you, we’ve put together a comprehensive list below.

What can a 12000 watt inverter run?

Choosing the right inverter model is very important because you want one that meets all your power needs. If you want to use several heavy and energy consuming devices, then a 12000 watt inverter is definitely the type you are looking for.

12000W is on the higher end of the power when it comes to inverters, meaning you can run multiple refrigerators, multiple power tools, and various other kitchen appliances if you want. Of course, it can also power lighting, computers or even air conditioners.

As long as whatever you’re trying to use doesn’t exceed the inverter’s total capacity, you can power just about anything you need. So if you want to turn on lights and kitchen appliances (refrigerator, coffee maker, microwave, maybe even stoves), you can.

However, it is important to note that you should pre-check the wattage of whatever you are trying to connect to the inverter. It is important not to overload the inverter, so you must ensure that the total power of the devices you are using does not exceed the capacity of the inverter. Device manufacturers put this information on their product labels to make it easier to find.

When buying an inverter, a general rule of thumb to keep in mind is that you want to buy an inverter with a nominal value of 15-20% more than the power you actually want. So if you want to use devices with a total of 9600-10200 watts, the 12000W inverter is perfect. If you want to use more than this, you may want to go for higher capacities as a 12000W inverter will run comfortably at 9600~10200.

Can I run commercial appliances with a 12000W power inverter?

A 12000 watt inverter is certainly suitable for larger/commercial devices. These devices often require about 1500-2500 W (each) to operate, but there are also some that require even more power. However, as long as the total of all units does not exceed 10200W, your 12000W inverter will run them all comfortably.

How many amps does a 12000 watt inverter draw?

The formula to obtain the current from an inverter is as follows:

Amperage = Watt / Volt

As such, a 12000W inverter has approximately the following amperage:

12000 / 110V = 109.09 amps

1. SUNGOLDPOWER 12000W Power Inverter – Pure Sine Wave

This 12000 watt inverter is one of the best available on the market today. Not only is it a pure sine wave inverter (more efficient than modified wave), it is also an MPPT solar charger, AC charger and even automatic transfer switch in one.

This inverter has a low frequency and AC priority (default), which means when there is an AC input, the battery is charged first before the inverter transfers the input to power the load. You can choose the battery priority so that the inverter uses the battery before the AC input.

The SUNGOLDPOWER inverter is packed with features such as: smart remote control, support for solar panels with MPPT function, AGS (automatic generator start), four-step smart/smart battery charging and more.

Sungoldpower inverter is reasonably priced for such a large capacity inverter. However, it costs a little less than the other investors we’ve listed here.
