Not too sure what you need from your off-grid inverter? Let our buyer’s guide help you there and show you some of the key features you should be looking for!
When it comes to purchasing an off-grid inverter, you will first need to decide what type of inverter you want. There are three types you can choose from, a Pure Sine Wave, a Modified Sine Wave, and a Square Wave.
These three types differ in terms of quality output power, compatibility, and price. Let’s take a closer look to help you differentiate between them.
Sine Wave Inverter
First up is the Sine Wave inverter. A sine wave is what you typically get from a generator and your local utility company where rotating AC machinery generates the sine wave. It is a natural product of this rotation and can be used in inverters.
A sine wave inverter is a fine choice as all the equipment sold on the market these days is designed for a sine wave.
This means that your inverter is likely to work with any other equipment that you have. It is still worth double-checking the compatibility before making your purchase to avoid any issues! Some appliances like microwaves and motors will only work on full output when connected to sine wave power.
Other appliances like light dimmers, battery chargers, and bread makers won’t work unless they are connected to a sine wave. If you intend to use your inverter to run any of these devices, then you will need a sine wave inverter.
It is worth noting that sine inverters tend to be the most expensive inverters, sometimes costing up to triple the price of other inverters! Be sure to check that your budget can afford this when looking for a new inverter.
Modified Sine Wave
Next, we have the modified sine wave inverter, which is similar to a square wave, but with an extra step added in! A modified sine wave inverter tends to work with most equipment, although its efficiency and power can be reduced over time.
Large motors like refrigerators, fans, and pumps will need more power from the inverter and use about 20% of the power.
This is due to the higher frequencies required to power these devices. It means that those on high frequencies will not be able to use the inverter, like fluorescent lighting.
If you use a modified sine wave inverter to power these you might notice that your lights will not be as bright, or they will make a humming or buzzing sound.
You might also find issues using this inverter with appliances that have electronic timers and digital clocks. These appliances tend to get their timings from the line of power. As they usually get 60Hz cycles per second and divide it down to one second, the clock can run as normal.
But as the modified sine wave is rougher and noisier than the pure sine wave we looked at earlier, your clocks might run faster or not at all.
You might also find that bread makers and other appliances that use 60Hz might not work at all. Usually, appliances that require electronic temperature controls will struggle with a modified sine wave inverter. In these cases, it is best to opt for a sine wave inverter to run these appliances.

Finally, we have the square wave inverter, which is the cheapest of them all. These inverters are difficult to find as there aren’t too many on the market, but if you are on a budget, it’s worth keeping an eye out for them.
Square inverters can run simple things like tools with universal motors, and that’s about it!
They are quite limited in what they can do, which is why they are a little difficult to find these days. Still, they are worth mentioning in case you want an inverter just for those universal motors.
It can be hard to find a square wave inverter, but for those up for the challenge, you can find them lurking in the corners of the web!
What Watt Do I Need?
Once you have decided which type of inverter is best for you, it’s time to turn your attention to the watt or size inverter that you need.
The wattage or power size of the inverter will be clearly stated on the specifications of the inverter so you can quickly check and decide if it is the right one for you.
You will also want to check the appliances and equipment that you wish to run on the inverter to ensure that it has the power to do this.
Check the wattage of each item you want to run and add them up. You will want an inverter to have enough wattage to power the appliances at the same time. If it does not you won’t be able to run say your microwave and lights at the same time.
Inverters come in sizes from 50W to a huge 50,000W. Usually, we don’t see units larger than 11,000W used in homes or other PV systems. When deciding which size is right for you, you will need to check the maximum surge and how long it lasts.
For those that aren’t sure, the surge is the maximum power an inverter can supply for a short time, ranging from a few seconds to fifteen minutes.
Appliances with large electric motors will need a higher startup surge to get them up and running, before the power they need drops down. Refrigerators and pumps are the most common appliances that need this high surge power.
When looking at inverters, the surge rating will come with the number of watts it can surge to and for how long it can maintain that power.
The capacity for this does vary from inverter to inverter, so be sure to check it for every inverter you look at. Usually, you will want a 3-15 second surge rating that will cover 99% of all appliances.
Usually, the inverters with the lowest surge ratings are high-speed electronic switching inverters, one of the most common types. These will come with a 25% to 50% maximum overload and apply to virtually all affordable inverters in the 50W to 50,000W range.
Those with the highest ratings tend to be transformer-based, low-frequency switchers. These inverters can handle a surge of up to 300% in short periods of time.
They also tend to be smaller and lighter units, but they tend to have a lower surge or peak capacity thanks to the smaller transformer.
We recommend checking the appliances you want to run to see what surge they need before making your decision. While a high-frequency switching inverter won’t have a higher capacity like a transformer-based inverter, the lower price point tends to sway many customers.
Along with the size and power of the inverter, you will also want to consider its weight. You don’t want an inverter that will be too heavy for you to move around and install. You also don’t want an inverter that could break any mounting brackets you place it on.
The weight of the inverter should be listed in the product description, allowing you to check it easily and find the best inverter for you.
There are plenty of light and compact inverters out there, especially high-frequency switching inverters. These also tend to be cheaper too than the larger and heavier inverters on the market.
Along with the weight, be sure to check the dimensions of the inverter. You will want to ensure that you have plenty of space for the off-grid inverter. Measure the inverter to ensure that it will fit in the desired space, the last thing you want is to be hit by any nasty surprises when it arrives.
Checking that the weight and size of the off-grid inverter suits your home before making your purchase will ensure a smooth installation and use of the inverter.
When it comes to installing the inverter, be sure to follow the instructions in the user manual to ensure that it is all done correctly.
Just like any device you buy, you want to ensure that it is safe to be used at home. The last thing you want to do is hurt yourself or any of your family members! When purchasing your inverter you will want to check that it comes with safety features that will offer you protection from any voltage problems.
Electricity can be extremely dangerous, so you need to check that any inverter you purchase comes with added safety features. Look out for any of the following protection:
- Undervoltage protection
- Overvoltage protection
- Overload protection
- Short circuit protection
- Overheating protection
This protection ensures that if anything goes wrong with your inverter or the devices and appliances it is connected to, you will be safe from harm. You will also want to check that any appliances or devices that you connect to your inverter are safe to use.
You don’t want to use any with poor or faulty wiring, or appliances that have previously been known to trip fuses or switches in your home.
By regularly checking and servicing your appliances you can help to keep them well maintained and ensure that any issues can be repaired quickly. Regular checks can also help your appliances to last longer, so it is worth doing.
You can find information about servicing your appliances by checking their user manuals, or by contacting manufacturers directly.
When purchasing your off-grid inverter, be sure to look out for safety features that will keep you and your loved ones safe while you use the inverter to power your home.
Protection for Appliances
Another feature to consider is the protection that your inverter can offer appliances connected to it. In some cases, the power passed to devices and appliances can harm sensitive internal components.
This mainly happens to mobile phones and laptops whose components are far more sensitive than those in larger appliances.
If you plan to charge your phone, tablet, laptop, or other devices with these sensitive components, then check that the inverter you have selected can do that. Often, modified sine wave inverters are not suitable and you might need to spend more and opt for a pure sine wave inverter instead.
It’s worth considering what appliances and devices that you intend to use with the inverter before making your purchase.
Most inverters will state if they can support devices with sensitive components or not. If they don’t state it, you can assume that they will not be suitable, or you can contact the manufacturer for them to confirm this.
Either way, be sure to find an inverter that is suitable if you are after one to charge your phone!
The cost of an inverter varies considerably, meaning you could have a bargain inverter, or splash the cash for a high-end off-grid inverter. Here, the choice is yours.
We recommend considering your budget carefully before making your decision. Consider how often you will be using the inverter, and how much power you need it to generate.
If this inverter is how you plan to power your home then you will want it to be a high-quality one, meaning it might be a tad expensive. But if it is going to last you for several years, it might be an investment worth making.
However, if the inverter is going to be used sporadically, then you can save some money and opt for a cheaper option.
Whichever you decide to do, be sure that the off-grid inverter is appropriate for your budget. There is no point stretching yourself too thin and purchasing an inverter that you can’t afford.
Stick to the budget and be sure to keep an eye out for any sales or deals that could allow you to get the inverter at a lower price.
