Top 10 Solar Inverter Manufacturers In The World & Their Reviews

What Are Solar Inverters? What are the top solar inverter manufacturers in the world nowadays?

A solar inverter or also known as a PV inverter is a type of electrical device which converts the variable direct current (DC) output of a photovoltaic solar panel into a utility frequency alternating current (AC). From there, the energy can be connected into a commercial electrical grid or inhouse usage in an off-grid system.

Solar power is not confined to low wattage and small devices. You can run large appliances on solar power including everything that needs electricity.

The solar inverter makes it possible by converting direct current (DC) into alternating current (AC). This inverter will allow you to run AC appliances directly on solar power.

Without a solar inverter, it is not possible to run your home appliances and devices on solar power. The reason is solar panels produce direct current (DC) power only.

So, you have to connect a solar inverter along with solar panels, and a charge controller to get the same electricity that you can access from the grid.

In this writing, we review top 10 solar inverter manufacturers in the world and their products including a buyer’s guide and description of inverter types. Let’s get started.

How to choose inverter for solar system

When it comes to selecting the best solar 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 have decided to go solar and you are looking for a solar power inverter, you will find several options while searching for a solar inverter including string inverter, micro-inverter, power optimizer, and central inverter.

Each inverter has different efficiency, capacity, and purpose. Before installing an inverter, you need to know your needs and the features of each type. It will help you to get the most suitable one that fits your needs.

A string inverter is most popular for a solar system that can be connected to a string between multiple solar panels. It works perfectly in a series of solar panels to provide you energy in collective ways. It is applicable for home and commercial solar systems.

Keep in mind that when using string inverters, if one or two solar panels stop functioning, the power production will be reduced.

If you have an individual solar panel or small rooftop, a micro inverter is perfect for you. This is the small inverter that will convert electricity independently from individual solar panels. You can install this inverter for a single solar panel too. It is efficient and very handy for small needs.

Power optimizer works to collect and send maximum output to the inverter. A power optimizer is connected to each solar panel and they ensure smooth and condition voltage to the inverter. This device will be perfect for you if you have a partial shedding issue on your roof. You will get up to 25% more efficiency with a DC to DC power inverter.

The central solar inverter is a powerful solar inverter that is designed for the commercial solar power station. It works like a string inverter to handle more power and efficiency. You can not use a central inverter for a residential solar system.

Types of Solar Inverters

Types of Solar Inverters
Types of Solar Inverters

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

We list 4 different types of solar inverters below.

String Inverters

String inverters are sometimes referred to as standard central inverters (simply call inverter — we will talk about it later).

Most small solar energy systems use 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 a 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. They are relatively easy to maintain.

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

Micro Inverters

This type of solar inverter is for complex, high-performance solar systems.

Micro inverters are also ideal for any houses with small rooftop space or a small solar system.

In microinverter PV systems, the micro inverter will be installed at the solar panel place. Then that micro-inverter converts solar energy (DC) to AC for later usage (same as string inverters).

That is quite different when it comes to the microinverter. The micro-inverter converts direct current energy into alternating energy on the rooftop only.

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 micro inverters, are located on the rooftops with the solar panels.

Power optimizers work differently, they do not convert solar energy from DC to AC directly but sends DC to the central inverters.

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

Compared to string inverters, a power optimizer PV system is more efficient. Just like microinverters, power optimizer PV systems improve solar panels’ efficiency.

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.

Central Solar Inverters

Central inverters convert the DC power collected from an array of solar modules into AC for connection to the grid. They are typically floor or ground mounted, as opposed to string inverters, which are typically installed on a wall or other vertical structure (Source).

Solar Inverters FAQs

How much do solar inverters cost?

Many solar inverters exist in the market, and they vary in price. The cost of the inverter depends on the size, quality, and size of the inverter.

A low-end 5Kw inverter can cost $850, while a high-end famous brand inverter may cost more than $1800. Most of the inverters come with a warranty of 10 years, which is an average of the solar’s expected life. Panel lasts typically from 25-30 years.

The inverters need to be replaced after 11 years of service due to its short warranty. The replacement cost ranges between $3000 and $20,000. However, it is recommended to buy a high end, good quality inverter with an extended warranty to minimize failure probability.

Are SUNGROW inverters good?

Sungrow is a Chinese inverter manufacturer founded by a university professor named Sungrow in 1997. Sungrow has a remarkable reputation for its simple, flexible, and robust inverters available at low prices. The inverters manufactured are in the range from 2Kw to 5Kw.

Their central inverter series includes SG1000TS, SG630MX, and SG800MX. The string inverter comprises SG3KTL, SG4KTL, and SG5KTL series. Sungrow also manufactures hybrid inverters known as SHK5 + ESS.

Sungrow inverters come with built-in wireless monitoring and an online monitoring portal with the name of Solar Info Bank. There is also a smartphone application for remote monitoring of the system.

SMA, Fronius, among others, have top-notch experience in manufacturing quality inverters, which makes them reliable. For a high budget, European inverters are available. However, for low budgets, Chinese Solar inverters are good.

Are micro inverters better?

These are small, lightweight inverters attached to each solar plane. Each solar plane works independently; therefore, failure at one point does not affect the performance of the entire system. In the case of the central inverter, the panels are dependent.

1. Maximum Power Point Tracking: MPPT is a technique used to find the specific value of the inverter voltage at which power generation is maximum. MPPT is applied on each solar panel in the case of micro-inverters, thus increasing the overall performance of the system.

2. No point of failure: The functional panels are still effective even in the case of micro-inverter/solar panel fault.

3. Panel wise monitoring; Individual panels are monitored, and separate performance reports for each panel can be obtained.

4. Easily Expandable: For central inverters, the system can’t be easily expanded. However, it is easier to expand the solar system with micro-inverters.

5. Safety: Micro-Inverters don’t need high voltage to operate, which improves the solar system’s and owners’ safety.

6. Lasting life: Micro-inverters come with a more extended warranty since they do not need high voltage and power loads.

Cost of micro inverters

Micro-inverters have a high initial cost as compared to central inverters. They cost $0.52/Watt –peak, their long lifespan, and easy installation makes them the best.

Dual Micro-inverters: It works like the regular micro-inverter, just that the dual micro-inverter is attached to two solar panels instead of one. The cost is reduced, but performance becomes low.

How does solar edge power optimizer work?

DC power optimizers are useful for panel-level monitoring and power optimization. Solar Edge optimizer uses the MPPT technique to track the specific voltage value at which maximum power is obtained. The point is called the maximum PowerPoint. The MPPT per module provides flexibility in design.

The power optimizer also monitors the performance of each module to the owner. This results in module-level monitoring and cost-effective maintenance.

The power optimizer is responsible for setting the DC voltage to a safe level in case of a grid or inverter shut down, and it comes with a warranty of 25 years.

PV Inverter Warranty And Service

Fronius, SMA, and SolarEdge, because of their effectiveness, have been on the top list for years. Fronius, Huawei, and SMA provide their inverters with a 10-year warranty while SolarEdge offers a 12-year warranty.

Emphase gives its micro-inverters a 25-year warranty. Low-end brands are repaired only when they are shipped to them. The repairs are not done immediately.

Final Thoughts

Finally, you have the top ten solar inverter manufacturer company reviews and ideas about their product range.

You can select a manufacturer that has established sales and service centers in your area. It will be easier to get fast installation and after-sales service.
