Choosing the right solar power inverter makes a difference

Spread the love

If you are considering solar power for your home or property then make sure you do the research. As the homeowner you will be interested in both the efficiency and the price of a solar power inverter. But do you really understand the choices? You need to do the research. Here is a quick synopsis to give you a lie of the land.

How to Choose the Right Solar Power Inverter

Once you have done the research work the calculations for your installation

To transform the direct current generated by solar panels into the alternating current used by families, you would need a solar inverter. So, it is considered to be the soul of transmitting energy. From this viewpoint, it is incredibly important to pick the right solar inverter for you whether you intend to go solar or purchase it for your solar power plant. 

Although faced with a multitude of online and offline modules and labels, you can find it hard to select the right one for you. Thankfully, this article might give you the answer on how to choose the right solar power inverter for you. 

Do some research

“Right of the bat”,  it is important to do some analysis and find out about the internet’s most used, trusted, as well as well-reviewed products. Or perhaps consider  having a quick retail tour to help you decide. When you visit the market, since they are the key ones, you will learn about the three main kinds of solar inverters. There will be off-grid inverters, grid-tie inverters, and hybrid inverters too.

Cheap or efficient – The right solar power inverter for you?

The professionals behind point out that the cheapest solar inverters from the bunch, which are not as efficient as they should be. Thus, it would be wise to do detailed research first and not focus on the price. In an interface that has one utility wire, a grid-tie inverter turns the direct current into an alternate current and aligns them together. This inverter doesn’t have a battery. 

It can pump the excess energy into the grid. In this technology, the MTTP system is used. As far as the off-grid inverter goes, it transforms the DC to AC, although from a storage battery. In larger schemes or for industrial applications, these types of grids are used, but a few smaller ones can still be used for home use. 

Off grid solar power inverter

The off-grid inverter is often considered as “stand-alone”. Finally, there is a hybrid inverter that transforms DC into AC. Both can be used in an off-grid PV and a grid-tie PV. This function makes the inverter very convenient as you can use it according to your needs.

What Should You Take Into Consideration?

There are various styles of sizes, labels, versions, and so on. Among these, choosing the right solar inverter requires some simple knowledge on your part of the terms. Any of the fundamental considerations are given below.

Protection certification for solar power inverters

Every reputable research facility certifies it.


It is the electricity that a machine uses when it is switched on. The Watt is represented by joules per day. When an inverter uses 20 amps for 12 hours, it is a device with 120 watts. It is the product of amps and volts.

Watt hours

This is the product of the number of watts and the number of hours used by the unit. It uses 900 watt-hours if a 100-watt bulb is used for 8 hours.


At the time, this is the indicator of electrical current. It is known as 1 coulomb in a second.


Amps are the product of times amps. It is the key battery power factor. Using its battery, most inverters run. The capacity of the Amp-hour defines the battery capacity and offers an indication of how long it will operate. Complete Harmonic Distortion, or THD, of less than six percent, is enough for one household. Regulation of the RMS voltage must be less than or equal to plus or minus 5. The control of peak voltage must be less than or equal to 10 percent.


The output power to input power ratio is defined as efficiency. 100 percent reliability is hard to obtain since, in the form of heat, some control is lost.  The solar inverter’s efficiency depends on the load. An efficiency graph is given in the specifications of the inverter. 

Internal protection

The components of the solar inverter must be secured against lightning surges, overload, and so on. In order to detect the issues and shut down immediately, it must include sensing circuits. If the voltage of the supply is lower, it must be switched off. Otherwise, it would discharge the battery and even destroy it.

Safety concerns with solar power inverters

It is really interesting and of utmost importance to be able to see how you can get some extra adapters as well as a tracking tracker from the solar inverter. Do not take it for granted that it will just perform properly only because it is placed in your household since there are occasions where it has been revealed that chips have been set inside the solar inverter for surveillance purposes.

So, that being said,  it is important that you look at these solar power inverter safety concerns. Although often, these tracking and monitoring systems also help, for example, they can give the company details back and if there is an issue with the product, it can communicate back to the company and they will take the appropriate action according to the severity of the situation of course. 

In any case, speak about the matter with the company you are purchasing the inverter from. 


Examples of solar inverters

String inverters

For a location where power consumption is less than 1 MW, these inverters are best. The solar panels are joined in the row in certain forms of inverters. All separate strings are connected to the same inverter.  All the strings bear the power of DC that is translated via the inverter into AC. It is the energy we have in our homes every day.

Central Inverters

This type of inverter is suitable for areas where power demand is higher than 1 MW. Such inverters are the same as string inverters, but a greater number of panels are supported. For a link with screens, these inverters want fewer components than string inverters.


For residential and commercial use, these inverters are the finest. These inverters are mounted separately on each plate. Microinverters directly transform DC power to AC power. Therefore, no string inverters are required. 

This is often used to calculate the output of each panel. In comparison, there are string inverters that can control the string output. In microinverters, if the panel’s output declines, the output of other panels will not be affected.

Now choose the best solar power inverter for you

So, therefore the question emerges how can one know or figure out which solar inverter is the best. Especially since anywhere, whether in the street or online, appears to be many non-branded and branded products.  As the homeowner you are likely looking for the best deal and more importantly the most efficient method.

Thus, it is essential to learn all there is and know about the solar power inverters and their suppliers. More importantly consider precisely how and what you should search for when it comes to choosing the best solar power inverter for you and your home.
