Solar Inverters 101: Learn What Type is Right for You

Solar power is a type of energy that comes from the Sun. It can be used to power homes and other appliances to generate electricity without using any fuel. The solar power industry is growing at an impressive pace, and many homeowners are opting for solar panel system.

If you’re planning to install solar panels, you need to have solar inverters in mind too. These inverters do all the heavy lifting of converting solar power into usable AC electricity.

Read this blog on solar inverters 101 for beginners that covers what it is and why you should install one in your home to get maximum benefits from solar energy.

What is a Solar Inverter?

Solar inverters are essential for a solar power system. They convert direct current (DC) power generated by solar panels into alternating current (AC), the standard flow of electricity required for electrical circuits and domestic appliances.

A hybrid solar inverter also connects to the grid to handle the flow of electricity and feed excess solar power back into the grid.

hybrid solar charger inverters also help in protecting battery life by regulating voltage and current of electricity being fed to batteries. They can also be used to troubleshoot issues by monitoring voltage and current output of solar panel and other components.

Benefits of Installing a Solar Inverter

Solar inverters are a vital part of solar power systems as power optimizer and have a number of benefits that homeowners should consider before choosing one.

Solar inverters can be used in on-grid solar power systems, off-grid solar power systems, and hybrid solar power systems.

They help households use electricity generated from the sun for powering electronic devices, providing clean energy and saving on costs.

Solar inverters ensure constant power output regardless of the weather conditions, shading and energy availability, making them an ideal choice for power home appliances.

Efficiency of Solar Inverters

The efficiency of solar inverters is the measure of how well a solar inverter converts solar power into usable energy.

Solar inverters are designed to minimize energy losses from solar panels, and they are among the most efficient power converters available today.

Solar inverter efficiency is measured by two numbers: peak efficiency and weighted efficiency. Peak efficiency is the maximum power output when it is operating at its peak capacity.

Weighted efficiency takes environmental input factors like DC input levels, temperature, and solar radiation into consideration. Conversion efficiency varies by brand, but quality inverters are usually 97-99% efficient.

Types of Solar Inverters

Solar inverters are used for solar power generation and conversion. They ensure that solar power is converted into usable ac electricity with Minimal losses.

The main types of solar inverters are string inverter, microinverter, hybrid inverter and central inverter.

Four types of solar inverters offer different features and benefits to suit different system needs.

String Inverters

String inverters are the oldest and most reliable type of solar inverter on the market.

With string inverters, solar energy is sent to a central panel. The inverter then separates the power into alternating current (AC) and direct current (DC) and regulates the voltage of each to produce electricity.

String inverters are less efficient at optimizing solar energy output, but they are good for off-grid solar power applications.

They are also good for stringing multiple solar panels together in a grid-tied system.

If multiple solar panels are stringed together, power output is optimized by stringing them directly to the grid rather than feeding them into an inverter.

String inverters can be used with different types of solar panel systems, including grid-connected solar panels and solar panel systems with energy storage capability.


Micro inverters are smaller and more versatile than large-format inverters.

They are commonly used to power individual panels in an array, as they can operate at a lower voltage than inverters.

Moreover, micro-inverters are connected to and installed at the site of, or behind, each individual solar panel in the array.

These inverters allow solar system owners to install multiple solar panels with minimal wiring and maintenance.

Hybrid Solar Inverters

Hybrid solar inverters are a hybrid of on-grid and off-grid inverters that can be used to power a solar system and power grid simultaneously.

They are designed to handle energy demands from the solar system while also feeding excess electricity back into the utility grid when required.

These inverters are versatile and can be used in both high and low power cut areas, making them an ideal option for homeowners with variable energy needs.

Hybrid Solar inverters that integrated MPPT battery charger controller also goes popular in recent days.

Central Inverter

A central inverter is a type of solar inverter that acts as the central point of power distribution for Large solar energy systems.

Central inverters are similar to string inverters, but have a higher capacity and can connect more solar panels together. They are typically used in large-scale solar installations with regular production across the solar array.

Central inverters have the highest capacity of any inverter type, and are therefore most commonly used in utility-scale solar systems, such as solar farms.

They are also designed to connect directly to the electric grid, with capacities ranging from 100 kW to many megawatts.

How to Select the Right Solar Inverter for Your Home

Consider where the inverter to be used and the type of inverter needed for your home.

and then, the most important, size the solar inverter based on your electricity demands.

Additionally, consider factors such as savings, life expectancy, price, and other factors when selecting an inverter for your home.

Comparing the Cost of Different Solar Inverters

The price of solar inverters varies depending on the type of inverter used and their sizes.

String solar inverter optimizers range in price from $1000 to $1600 or more.

Central inverters price range from $3000 to $15000 or more.

Micro inverters Price range from $70 to $200.

Hybrid solar inverters Price range from $600 to $1300 or more.

Sizing a Solar Inverter for Your Home

When sizing a solar inverter for your home, first determine the wattage of the system and then compare inverters with similar wattages.

Next, consider volts and Amps needed by your appliances in order to operate properly.

Choose an inverter that is appropriate for your appliances and system size.

with all factors are considered, you will have the good option.

Local Regulations on Installing a Solar Inverter

Most solar inverters are UL listed, meaning they have been tested and meet safety requirements.

However, in some areas of the country there may be local regulations that prohibit the installation of certain inverters.

If you are uncertain about your local regulations or need assistance finding an inverter that meets your specific needs, consult with professional installers.

How Long Do Solar Inverters Last?

solar inverters typically last 10-15 years, but this depends on how often they are used and how well they are maintained.

Pros and Cons of Different Solar Inverter Types

Inverters with solar batteries are the powerhouses of solar power. They convert battery stored dc electricity into usable AC Power, and can be divided into string inverter, central inverter, and micro inverters types.

Inverter types vary in terms of performance, cost, size, and other characteristics.

String inverter is a type of inverter used for medium- to high-output solar power systems with grid-tied. It is a variable-frequency inverter that produces direct current (DC) output voltage using solar power input as the input voltage.

Central inverter is used in large scale grid-tied system to regulate whole system output voltage from battery bank or grid.

Microinverter is a type of inverter used for small solar pv system. The microinverter operates as a small solar panel inverter to convert dc output voltage from solar panel into ac output voltage.

They have different functionalities and different pros and cons as well. It’s important to understand the various inverter types before purchasing one
