Best 1,000-watt Inverters – A Snapshot

Below is a quick snapshot based on consumer purchases.

The top two Pure Sine 1,000W inverters purchased on this site are Bestek and Renogy inverters.

  • Bestek is popular among tent and car campers. It is not as powerful as others, but it has 2AC outlets and two USB ports. It is a dependable inverter, and since many people only use it to charge electronics when camping, they don’t need as much power as they would if they were using small appliances.
  • Renogy is purchased more by RV and off-grid home groups. This reliable inverter does not take up a lot of space, and Renogy products have a good reputation. In addition, the renogy inverter is consistent and durable.

Kreiger is easily the most popular Modified 1100-watt inverter. This inverter is a workhorse and is often purchased by people using tools and small, non-sensitive electronics like lights, etc.

Best 1000-watt Inverter – Decision Criteria

There are several criteria to consider when choosing an inverter. Some of them are personal preferences like size, noise, etc., depending on where and how you will use them.

  • Pure Sine vs. Modified
  • Rating
  • Noise
  • Power Output Outlets/Ports
  • Safety Features
  • Size

Pure Sine vs. Modified

In addition to Pure Sine and Modified Inverters, there are alsoHigh-Frequency and Low-Frequency Inverters.


A modified inverter isreliable and less expensive than a Pure Sine inverter and can run most tools and household appliances.

Below is some equipment that may not work as efficiently with Modified inverters and some results you may see if you try and use it.

  • Motors may use more power because they have to work harder.
  • Fluorescent lights often make a buzzing noise, flicker, and are not quite as bright.
  • Clocks, mostly digital clocks, may not work with a modified inverter.
  • Timers may not work.
  • Temperature controllers may not always work.
  • Computers, cell phones, and tablets are considered sensitive. As a result, they may not only not work but also be at risk of damage.
  • C-Pap machines and other medical equipment are also sensitive equipment that should use Pure Sine inverters.

Although there are disadvantages to using Modified inverters, they are inexpensive and run most tools, appliances, electronics, etc. The technology continues to be improved, and many manufacturers will insist they can run the same equipment as Pure Sine inverters, but science tells you this is not the case.

Pure Sine

Pure Sine Waves are what your local utility company produces.

These inverters are more expensive but can run any equipment. They are better with sensitive equipment.

High Frequency

The Best 1,000 Watt Inverter - Dependable and Efficient! | SolarKnowHow (1)

High-Frequency inverters are what you most often find sold.This is because they are less expensive, small, and don’t handle industrial loads or low-frequency inverters.

These inverters are good with computers, electronics, small appliances, and small tools but don’t handle machines requiring large loads well – pumps, motors, and some tools with high torque.

Low Frequency

Low-Frequency inverters have an iron core, are more expensive and durable, and usually have more features and versatility.

These inverters can handle much larger loads; some included features are listed below.

  • Hardwire additional external GFCI outlets
  • The input of multiple DC voltages
  • Dual output voltages (120/240VAC)
  • Integrate battery chargers and transfer relays

Note that manufacturers are cutting back on producing low-frequency inverters with a 1000-watt capacity or less. Nevertheless, there are still some low-frequency systems in the market, although many double as battery chargers.


The Best 1,000 Watt Inverter - Dependable and Efficient! | SolarKnowHow (2)

Planning is essential when building your solar system, and choosing the correct inverter is critical.

Make sure you know the total amount of wattage you will use.You don’t want an inverter that is too small, nor do you want to waste money on one that is larger than what you need.

The chart above provides standard wattage for many appliances, but the information is also available on the devices and electronics you use.

(Video) What Can a 1000 Watt Inverter Run?

The wattage listed on the back, bottom, or plate is the maximum amount of power used.


When choosing the best 1000-watt inverter, a noisy converter behind your truck seat or in your RV and Camp can be annoying.

On the other hand, it does not matter if the inverter is loud if you are using noisy tools. This is why many contractors choose Modified Inverters. They may be a little noisier, but it does not matter where they use them.

Consumers will let you know if an inverter is noisy,so check out reviews and forums. I have also captured that information in the longer reviews below.

Power Outlets/Ports

Most inverters have 110AC Outlets and both 2.1 A and 2.4 A (Smart) USB ports.

I don’tcare much about USB ports on a Modified Inverterbecause I’m probably not going to use a Modified inverter for my sensitive electronics.

On the other hand, AC outlets are critical for my tools, and if I’m only using tools, then a less expensive Modified inverter is fine.

A Pure Sine inverter must have USB ports when I’m camping or in an RV or cabin. Kids like to play games and watch TV; I need them for my laptop and phone.

Safety Features

The Best 1,000 Watt Inverter - Dependable and Efficient! | SolarKnowHow (3)

Most modern inverters have safety features, with two critical features being surge protection and temperature control.

When deciding on the best 1000-watt inverter for you, high voltage, voltage overload, short-circuit protection, etc., are all safety features.

In addition to LED indicators, alarms, and LCD Displays,modern inverters have Smart Coolingfans that turn on and off the inverters according to preset temperatures.


(Video) TOP 4 Best 1000 watt inverter 2023

One note on size and weight.CHECK THE MANUFACTURER’S WEBSITE.Amazon specifications are often wrong, so check the manufacturer’s specifications. I’ve done this in the comparison guides.

Size is dependent on where you put the inverter. Are you squeezing it into a small, tight space in your car or boat? Do you have much more room in your truck or cabin?

When choosing the best 1000-watt inverter, measure your space requirements before purchasing.

The Inverters I like and Why I Chose Them

There are a lot of inverters to choose from, but they all have their differences. If you read the 2000W inverter article and the 3000W inverter article, you will find that the same inverter may not be reviewed in both articles. This is because some manufacturers make better low output inverters, and some produce better higher output inverters.

Many people will look at my choices and immediately say, “Well, “XYZ” is so much better,” I’ll agree there are other inverters that are just as good, but these are very good inverters, and they meet my requirements.
