Before you figure out what is the best power inverter for your RV, it is good to review what a power inverter is used for. Basically, power inverters allow you to convert the Direct Current (DC) 12V power supply in most automobiles and RVs to the 110V Alternating Current (AC) used by most household appliances.
Inverters are rated by wattage, and this rating is what determines how many AC power devices you can have connected and powered by your power inverter simultaneously.
To choose the best inverter that meets the AC power demands in your RV, you want to choose the correct inverter for reliability, safety and performance. To make that decision easier, here are some reviews and a buyer’s guide to help you purchase the best 2,000 watt power inverter for your needs. Take a look at the reviews and comparisons below.

BUYER’S GUIDE
What is the difference between a modified and a pure sine wave inverter?
Modified sine wave power inverters are designed to function optimally with most AC appliances. Sometimes power tools will experience a loss in power using a modified sine wave inverter, but it largely depends on the power draw of the tool and the power output of the inverter.
Pure sine wave inverters are the type of inverters provided by utility companies that allow appliances to function to full factory specifications regardless of what device is connected to power. These tend to be very costly and intended for use with solar power systems as opposed to automotive DC current.
Are 12V appliances better than using AC appliances on a 110V power inverter?
In terms of power efficiency, 12V appliances like those used by long haul truckers and in larger RVs are better than using standard AC appliances on a 100V power inverter. Any time you convert current, voltage or amperage you are going to reduce the power efficiency and potentially affect the performance of the connected devices.
The real question is whether you are willing to pay the significantly higher prices for 12V or 24V DC appliances for your RV. These appliances are far more costly than their AC counterparts, and using a standard AC appliance even with a power inverter is always going to be more cost effective. If money is no object, do as you will. If not, you’re better off using an inverter.
How would I use a power inverter in my mobile home?
Typically, you will need to wire the inverter directly to the vehicle battery terminals to draw electricity safely. Once properly connected to the battery, the inverter can be mounted in a convenient location in the front of your RV and appliances connected via extension cord.
What size RV power inverter do I need?
Check the wattage for each appliance you want to connect to see how many watts it uses. Electric ranges, hot plates, electric griddles and similar appliances draw the most wattage, so you probably can’t run them at the same time as your coffee maker. Appliances like refrigerators, TVS and electronics often draw significantly less wattage, so you don’t need to worry as much about overloading the inverter. The only reason you need additional wattage is to ensure you can run multiple high draw appliances simultaneously.
How much can a 2000 watt inverter handle?
Your 2000 watt generator can handle a deep freezer with 500-watt power, can cook with a 650-watt microwave, and can light a few bulbs.
How do I determine if an RV power inverter is working or if it needs to be replaced?
If you notice flickering lights or unexpected power loss from your appliances, more than likely it’s time to replace your power inverter. You may also see low voltage alerts displayed on the front of the power inverter. You may also want to test the AC outlets to ensure they are putting out the correct voltage with a multimeter. That is the best way to make certain your inverter has a problem.
CONCLUSION
My recommended choice out of all these 2,000 watt inverters is the Krieger KR2000. It’s built with a metal housing, has high frequency capacitors, large aluminum heat sinks and includes a remote control panel. Best of all, it has multiple safety ratings by independent safety review agencies, giving you peace of mind about safety and reliability.
If you are installing your first inverter or replacing an older model, check the KR2000 out first. It’s an exceptional value that will provide you with years of reliable service.
