Deciding on the best 1,000-watt inverter is a tough decision with all of the choices available.

In this article, I have worked hard to provide unbiased feedback that will help you make a good choice.

This article is based on my experience, forum feedback from RV owners, truck drivers, contractors, campers, industrial users, etc., and of course reviews.

I have provided two quick comparison guides, and more lengthy explanations and reviews.

These are the inverters most commonly purchased through this website, that perform well and have good feedback.

This section is for people like me that want a quick snapshot.

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

A couple more quick facts.

There are several criteria to consider when choosing an inverter.

  • 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 also High-Frequency and Low-Frequency Inverters.

Modified

A modified inverter is reliable and less expensive than a Pure Sine inverter, and it can run most tools and household appliances.

Sensitive equipment, like what is listed below, may not function properly.

  • Motors will use more power
  • Fluorescent lights may buzz or make other noises and not be as bright
  • Clocks
  • Timers
  • Temperature contollers
  • Computer, cell-phones, tablets

Over a period of time, sensitive machines can be damaged, but because Modified inverters are inexpensive and run most tools, appliances, electronics, etc., they are the most common inverters sold.

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

Pure Sine Wave

High-Frequency inverters are what you most often find sold. They are less expensive, small, and don’t handle industrial loads as well as 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, durable, and usually have more features and versatility.

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

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

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

Rating

how much power do you need

Planning is important 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 appliances and electronics you are using.

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

Noise

A noisy converter is annoying behind your truck seat or in your RV and Camp.

On the other hand, it does not really 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 really matter because of 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 both 110AC Outlets and both 2.1 A and 2.4 A (Smart) USB ports.

I don’t care much about USB ports on a Modified Inverter because 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, and I need them for my laptop and phone.

Safety Features

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

Other important features you may find include high voltage, voltage overload, short-circuit protection, etc.

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

Size

One note on size and weight. CHECK THE MANUFACTURERS 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?

Measure your space requirements before you make the purchase.
