Now that you have seen the top-rated solar inverters on the market today, it’s now time to learn a bit more about the individual components that help make these power-saving devices fantastic options. In this buying guide section, we’ll speak more about all of the important parts of solar inverters and what you should look for. If you still have questions after reading this part, we’ll answer a few of the most frequently asked ones below. Finally, we’ll give you our top three solar inverter picks in our verdict.
Advantages of solar inverters
The biggest advantage of solar inverters is that they provide an efficient and clean way to turn direct current (DC) power from the solar panels to alternating current (AC) power. The converted energy is then usable in homes and is able to power the appliances and lights throughout the house, barn, or RV.
Another benefit of solar inverters is that they are quite powerful to allow you use multiple appliances at the same time. On top of that, they attract people’s attention because they don’t cost much.
What also surprises many people is how easy it is for solar inverters to be installed. Apart from the easy installation, it is also very easy to maintain as well. These devices are quiet and efficient, so you will be able to get the most of your panels.
How to pick the best solar inverter?
Solar inverters don’t come in a one-size-fits-all approach. When choosing the best solar inverter, it often will come down to your specific needs and how much power you require to power your house or barn. You might want to focus on one specific feature or several of them. Nonetheless, there are lots of different individual aspects to consider. They include the product’s type, power output, input/output voltage, efficiency, cooling system, outlets, noise level, dimensions, weight, and lastly, the price. These features are the most important ones to pay attention to when picking the best solar inverter, and we’ll explore each below.
While both grid-tie and off-grid solar inverters are excellent ways to get clean energy, there is one very notable difference between them. With a grid-tie solar inverter, they are generally much easier to install and hook up the wires. This is because there are only two primary parts, the solar panels and the inverter itself, that’s it. The power from the solar panels (DC) are converted to AC through the inverter.
On the other hand, off-grid inverters are a bit more complex to install, and that’s because they have additional parts in the process. The inclusion of a battery can often make the entire process a bit harder. This battery requires a charge controller, so this might take you a while to connect everything.
When dealing with the power output and the input/output voltage (below), it’s really important to refer to the manual datasheet before installing anything as it will provide you with the proper information. Referring to this sheet will allow you to choose the right inverter for the number of solar panels you have.
The input and output voltage figures represent the level of power going in and out. The input figure is usually is presented as its maximum power input, and this figure represents the maximum amount of power (current) that the inverter can withstand. Therefore, if your solar panels are producing more power than the maximum input figure can withstand, then the current will be disrupted.
The output power figure represents the voltage your solar inverter can provide. If you’re using your solar inverter for your house, an output power figure of 110-120 AC is a standard.
The efficiency is also another notable parameter you’ll want to pay close attention to. In an optimal environment, the efficiency figure refers to the amount of energy converted. Most inverters will sit anywhere in the range of 90-95%, which is almost ideal. As you can see with the solar inverters on our list, all of them are able to touch 90% efficiency with the highest number coming from the SolarEdge SE3800H HD Wave Grid Tied Inverter at a whopping 99.2%.
Anytime you deal with power, you’re naturally going to come across the heat. Because inverters are working hard to supply power to the house, there will be some excess heat. There are generally two ways in which an inverter can be cooled.
The first is through an internal fan, and it is known as forced heat dissipation. These fans generate airflow within the inverter and slowly helps to cool it down.
On the other hand, inverters can also be cooled through convection. Convection cooling is a natural heat dissipation method that you can often find in these devices.
The number of outlets depends on which particular solar inverter you invest in. Some like the WZRELB DC to AC Pure Sine Wave Inverter and the Giandel 600W Pure Sine Wave Inverter both come with 2 American 120V outlets. There are models that also come with USB outlets that allow people to charge their devices.
The solar inverter that features the highest number of AC outlets is the AIMS10000 Watt Modified Sine Power Inverter. It boasts 4 of them, so you can use multiple appliances with it simultaneously.
Generally, solar inverters are quiet devices, although not completely silent. They will produce a low buzzing or humming sound when working, but it is not loud or distracting at all. It's best to keep the inverter away from busy spaces in the house if you find the noise level to be distracting for you. However, if you hear your inverter making louder sounds than the normal humming, you might want to inspect it as there could be issues with it, or it could use maintenance.
The sizes of the solar inverters vary. It is good to get an understanding of how big your unit will be. For example, our Editor’s Choice, the WZRELB DC to AC Pure Sine Wave Inverter, is 18 inches wide, 10 inches tall, and 4 inches deep. The largest solar inverter on our list is our Upgrade Pick, the SMA Sunny Boy 6.0-US 6000W Grid Tie Inverter, and this one measures 29 inches wide, 21 inches tall, and 8 inches deep. For those who need something smaller, the Giandel 600W Pure Sine Wave Inverter has you covered at 8.5 inches wide, 6 inches tall, and 3 inches deep.
The weight of a particular model depends on how much power it offers. While you can definitely find options that are extremely light, such as the Enphase IQ7-60-2-US, which only weighs 2.4 pounds, most of the solar inverters are going to weigh much more than that. One should expect a solar inverter to weigh closer to the SolarEdge SE3800H HD Wave Grid Tied Inverter, which is 25 pounds. This is a good benchmark since you’ll find ones below it or above it.
What else can be important?
Not every solar inverter comes with extra features that can include wires or cables, but for the most part, these solar inverters will simply give you what you need to get started. If you need longer cables, you’ll most likely have to get that on your own, especially if you have a more spacious house. Some solar inverters can come with remote controls as well, which makes them a bit easier to control since you don’t have to come to program it. For solar inverters that require a battery like the Renogy Pure Sine Wave Inverter, also comes with its own battery wire.
The thing about the cost of solar inverters is that you can find one for almost any price under the sun, as we’ll illustrate. In general, solar inverters aren’t very cheap, so you will have to keep that in mind. But, since they can lower your bills, they are still a worthy investment. The most affordable solar inverter on our list is our Best Value pick, the Giandel 600W Pure Sine Wave Inverter, which goes for roughly $120. You can compare that with our Upgrade Pick, the SMA Sunny Boy 6.0-US 6000W Grid Tie Inverter, which you can find for $1400. Our Editor’s Choice, the WZRELB DC to AC Pure Sine Wave Inverter, is available for $300.
When it comes to installing and setting up your solar inverter, just know that setting up a grid-tied model is much easier than an off-grid one. To connect a grid-tied solar inverter, all you have to do is to hook it up to your solar panels using the necessary wiring. Installing an off-grid solar inverter is more complex because it incorporates a battery where the energy is stored and a charge controller. While it’s not overly complicated to wire the inverter, battery, and solar panels, it will take substantially more time to do so.
The best solar inverters should last between 10 and 20 years, but it can be less or more than these numbers as well. The lifespan of your solar inverter will depend on the conditions and humidity it is exposed to and how often it is in use. If you need more power from it, it might mean that it will be replaced sooner. A good way to ensure a longer lifespan for your solar inverter is by purchasing a high-quality one with a good reputation and warranty.
Maintaining your solar inverter is incredibly important to make sure it lasts longer. Whenever issues arise with your solar inverter, it’s best to refer to the manual that comes with it to troubleshoot your problems there. Keeping your solar inverter in the right spot is also important too. Avoid exposure to sunlight and rain as it can severely damage your unit. Another tip is by maintaining your solar inverter by going on a proper maintenance plan. A good rule of thumb is to have your solar inverter serviced or checked every 6 months to ensure proper working conditions.
