Top Six 1000 Watt Inverters

The Top Six 1000 Watt Inverters for Going Off Grid

The battery you have in your solar panel system stores power in DC energy – which you cannot use to power your appliances. If you have a sizeable solar panel system, you will need at least a 1000 watt inverter to convert your stored DC current into usable AC current.

But finding the right 1000 watt inverter is a lot more challenging than you’d think. 

You must sift through hundreds of options to find one that meets both your quality and price requirements, and if you don’t know what you should be looking for, you will end up wasting money on the wrong inverter.

Lucky for you, you found our post.

We’ve shortlisted six of the best 1000 watt inverters money can buy. But before you read our recommendations, you must learn about the different types of 1000 watt inverters so you can make the right decision.

After all, you don’t want your decision giving you trouble when you’re off the grid.

How to Pick the Right 1000 Watt Inverter for Going Off Grid?

There are six things you need to consider when looking at a 1000 watt inverter:

Power Rating

It gives you an estimation of how much power the inverter can handle. While getting an inverter that can power all of your appliances may seem like a good idea, your battery and solar array must also be large enough to make that happen. 

Furthermore, getting an unnecessarily powerful inverter will needlessly add to your expenses. Confirm the power requirement of the appliances you run, and estimate the maximum power you will use in one go. 

Never underestimate your usage because you will be disappointed if the inverter doesn’t support your needs later.


One of the things you need to remember is that inverters make noise when in use. Knowing that you’ll likely be using the inverter in an RV or a boat with limited space, you must make sure that the inverter you get isn’t too loud.

You don’t need a buzzing sound bothering you when you’re in bed after a long day of traveling. 

However, if you intend to use your inverter to run noisy tools, the noise it makes won’t make a difference.

Number Of Outlets

Power inverters have been one and three outlets, and if you want to power several devices in one go, you will need to get an inverter with more outlets.

Most inverters on our list have two outlets, leaving you one less thing to consider.

USB Ports

While not every inverter has it, most new inverters come with USB ports.

You will be able to power most laptops, tablets, power tools, and even some gaming consoles like the Nintendo Switch using these ports.

Some inverters come with these ports in conjunction with the power outlets, while some do not.

If you have a lot of electronics, getting your hands on an inverter with these ports is an excellent idea.


One of the features the inverter you get must have is the safety feature. It prevents your battery from draining by cutting off the power when the battery reaches a preset temperature.

Ensuring that your inverter has power surge protection is also a good way to know that the inverter you buy will last you for years.


Lastly, but perhaps most importantly, is the size of the 1000 watt inverter. If it’s too big for your RV or boat, there is no point in buying it. 

The best way to ensure that an inverter fits the area you’ve assigned for it is to compare the area’s measurements with the dimensions of the inverter.

Types of Inverters and Which One You Should Get

Modified Sine Wave Inverter

If you need an economical option that can power most appliances without any hassle, the modified sine wave inverter is right for you. These cost a lot less than true sine wave inverters do.

However, these inverters can damage sensitive electronics over time. Also, control panels on your microwave likely won’t work with the sine wave inverter.

It is vital for you to know that CPAP machines do not work correctly with modified sine wave inverters. While these are perfect for use in RVs, these aren’t right for most residential use cases.

Pure Sine Wave Inverter

While pure sine wave inverters are significantly more efficient than the modified kind, they are a lot more expensive, too.

However, what makes them worth the higher prices is that they can be twice as efficient as modified sine wave inverters when powering certain appliances.

These inverters also do a much better job at powering sensitive electronics such as microwaves.

Pure sine wave inverters are of two types:

Low Frequency Pure Sine Wave Inverter

Low Frequency or LF inverters are larger, heavier, and more expensive than High Frequency inverters because they come with a large copper transformer.

If you use air conditioners and compressors regularly and for long periods, LF inverters are the right kind to buy. These work exceptionally well with appliances that require high starting power.

High Frequency Pure Sine Wave Inverter

HF inverters are a lot lighter and have smaller transformers, making them cheaper. If you only intend to use your inverter a couple of times a week, this is the right kind of inverter to get.

If you power many smaller electronics – think phones and laptops – and no “heavy” appliances, an HF inverter will never disappoint you. 

Most inverters rated 1000 watts and lower are LF inverters and will only power smaller appliances and tools. You shouldn’t look into getting an HF inverter unless your appliances need it to work.

I am an outdoor nut and love researching and testing new gear. For me its about finding that diamond in the rough…not just shelling out $$ for the sake of it. Its tough to decide between the mountains and the ocean so I try and travel alot and bring my Australian Cattle dog where I can (but he does not like boats).
