Solar Power Inverter: How to choose inverter for Solar System

Solar power plays an important role in our day to day lives. But when we talk about solar system equipment, we are not only talking about solar panels alone.

Many things make up a piece of solar system equipment. Choosing a good solar power inverter also play an essential role. In this article, we are going to discuss solar power inverters. 

A solar power inverter’s role is to convert the energy that is got from the sun into usable electric energy that can be used in homes, commercial buildings, powering home appliances, lighting, electronics, and many other home uses.

In the absence of a solar inverter, we would not be able to get energy from the sun into the solar panel.  We cannot use solar energy obtained by the solar panel without first converting it into usable energy.

That is why a solar power inverter is essential when it comes to powering our homes using solar energy.

A solar power inverter is an essential part of the whole solar PV system, and it is also the part that is most likely to have issues,

Considering that they are in extreme weather conditions like humidity, rain, and extreme heat. A solar power inverter can convert variable direct current (DC) power into the utility usable alternating current (AC) power.

When sunlight reflects on the solar panel, photovoltaic electrons get to work and can produce direct current energy. 

Houses mostly use alternating current and not direct current energy as many could think. Solar panels mostly produce direct current, and that is where the solar power inverter comes into play. The first step is where the solar panel collects sunlight and turns it into energy. 

When that energy is converted to electricity using the solar power inverter that converts direct current energy into alternating current energy. People are going solar, and many people are buying more and more solar panels. 

They have started to realize the importance of solar energy, and one of them is that it saves money, and there are no monthly bills that come with using solar energy.

Before you decide to go solar entirely, you will need to do your research on the different types of solar inverters, which ones are the best, and which ones are compatible with your solar panel. 

Generally, a solar power inverter’s whole process is to convert direct current and alternating current.

Which is then used directly in many homes and commercial buildings. Different solar power technologies have different types of inverters.

If you decide to use a solar panel at your home, getting to know which type of inverter works for you is very important.

All the solar inverters you will find in the market have different functions, and each one of them works differently from the other.

To get to know the different types of solar panels, we have given you different types of solar inverters below.

String Inverters

The string inverters are sometimes referred to as standard centralized inverters.

Most small solar energy systems use the string inverters technology for their daily activities. In this type of technology, each solar panel is wired to a specific string.

When a solar panel produces solar energy, it will be distributed into the single string inverter. 

The inverter then converts the direct current energy into alternating current.

These types of solar inverters are of low cost and very inadequate, and they are relatively easy to maintain.

If you are looking for a low-cost solar power inverter, then you should use the string inverter. It will work well for those people who have direct sunlight throughout the day.

Micro Inverters

This type of solar inverter is for complex systems and is meant for high-performance technology.

These types of inverters are ideal for those houses which have small rooftop space.

For the micro inverter PV system, a small inverter will be installed at the solar panel site. As we saw earlier with the string inverter, it sent solar energy from the solar panel to a single inverter.

That is quite different when it comes to the microinverter. The micro-inverter converts direct current energy into alternating energy on the rooftop only. Microinverters are highly-priced compared to cheap micro inverters.

Repairing a micro-inverter might be difficult as it is located on the roof with the solar panels.

Power Optimizers

A power optimizer’s solar PV system is a combination of both string inverters and micro-inverters.

Power optimizers, just like the microinverters, are located on the rooftops with the solar panels.

Power optimizers work differently as they send solar energy into a centralized inverter.

It does not convert solar energy directly into the alternating current from the location where the solar panels are located.

Still, instead, it conditions the direct current by fixing the voltage of electricity.

Compared to a string inverter, a power optimizer PV system is more efficient. Just like microinverters, the power optimizer PV system will improve the efficiency of your solar panels.

If you are a homeowner and you are willing to pay more for the efficiency of the solar panels, then you should get yourself a power optimizer.

Battery Inverters

If you are a homeowner and you have decided to go solar, you will need to separate your solar panels and the battery.

A battery inverter is used to separate the two batteries from the solar panels.

It converts the battery power into the 230V current and then delivers it into your switchboard.

How to Choose the Best Solar Power Inverter for Your Home?

If you have decided to go solar and you are looking for a solar power inverter, you have three choices to choose from.

As we have seen in this article, different inverters work differently from the other, and their efficiency rates are also different, but the primary function is the same. 

When it comes to selecting the best inverter for your home, the first thing that you need to do is to look into your pocket and decide how much you are willing to spend on a solar inverter.

If you are willing to pay for the additional maintenance, then you should probably go for the highly-priced solar inverter, which is also very efficient. 

The three options will include going for the cheaper string inverter or the highly-priced micro-inverter.

You can settle for the power optimizer, which is higher than the string inverter but lower than the microinverter.

If you live or stay in an area where you receive direct sunlight throughout the day, you can decide to go for the string inverter. 

It works best in such environments. But you should keep in mind that when using the string inverter if one or two solar panels stop functioning, the power production will be reduced.

If you have a small rooftop, then the micro inverter will work well for you.

The only one disadvantage that comes with micro-inverters is that they are expensive, and when it comes to repairing them in case they get faulty, it will be much more difficult.

The power optimizer can be another option that you can decide to go for. It is a combination of the string and microinverter. 

This system is very efficient for your solar power system, but it is more expensive than the string inverter.

So, if you have decided to go solar, you should look carefully at the above factors and then decide on which type of inverter will work well for you in your home.

Factor to Consider About A Solar Inverter

Many people have decided to go solar, but many of them do not know what to look for when it comes to purchasing a solar inverter.

Before you decide to buy a solar panel or install one in your home, there are different factors that you need to keep in mind.

Different companies are manufacturing solar inverters. There are so many solar inverters in the market today.

In general, inverters all claim to be the best when it comes to PV systems, which might be accurate, but you should always get your facts right before buying one.

As we all know now, microinverters are the best when it comes to efficiency, and they are highly-priced.

But before placing the purchase to buy the inverter, you better confirm your needs and answer the question: Is that expensive inverter able to solve your problems.

People who get a lot of sunlight throughout the day should probably go for the string inverter, which is not expensive.

As we now see, the price will depend on your needs and how much you are willing to spend.

So always spend wisely.


Most companies that manufacture solar inverters have a warranty that comes with the product.

Check out the different types of warranties that different companies offer before deciding on one specific solar inverter.

Some companies will provide a less warranty while others will provide a more extended warranty.

You should always go for the product with the highest warranty time frame. It will give you time to use the product and get to know how it functions. And in case of any problems, you can easily take it back to get a replacement, or get your money back.

Customer Reviews

Every inverter that is sold on the internet must at least have customer feedback or review.

It is important to check out what different customers had said about a specific product. A product with fewer reviews does not necessarily mean that it is faulty, but always go for the product with lots of good reviews.

Pro tip: Checking out customer reviews is the best way to get to know if a product is good or not.

Always check the latest reviews and do not depend much on old reviews. Different products are made every day, and with the technology change, you will always find different feature has been added to the product daily. That changes will improve on its efficiency.
