The Best Solar Grid-Tie Inverter: Overview

Grid-tied solar systems are setups powered by solar energy and connected to the electricity grid. They function without a piece of backup battery equipment.

The sun cannot always supply power to solar systems, especially at night. This is why all grid-tied solar systems need a place to store the leftover generated energy.

Some people get a battery bank to store this energy, while others send the electricity into the utility grid, thereby, using the utility grid as a battery. Unlike other options, this costs nothing.

Grid-tie inverters convert the direct current (DC) into alternating current (AC). They also ensure that the voltage is suitable for the power grid, accurately matching the electrical system’s requirements to prevent overloading the distribution line.

The photovoltaic (PV) cells of the solar panels turn light into direct current (DC) electricity. This needs to be converted into alternating current (AC) before it can be used to run household appliances.

The grid-tie inverter manages the power from the solar panels so it is first sent to supply energy to the household before the excess is exported to the grid. They don’t require any batteries or other forms of energy storage to store solar power, making grid-tied solar systems cheaper and easier to install.

 The functions of a grid-tie inverter can be simplified into two main parts: (a) the extraction of direct current (DC) from the solar panels and (b) the conversion of the extracted direct current (DC) into alternating current (AC) at a suitable voltage and frequency.

It functions like the brain of a solar system and manages the flow of power throughout the system, converting the captured direct current into usable alternating current power.

Types of Grid-Tie Inverters for Solar Systems

There are three main types of solar inverters for grid-tied solar systems, namely; micro, string, and central.

Micro Inverters

These inverters are made up of a small box found on the back of a solar panel. The function of a microinverter is to convert the direct current (DC) electricity produced by a single solar panel.

They are small weatherproof inverters that are suitable for solar systems in shaded areas. They also allow continuous power if one of the units is down and give room for expansions in the future. 

The concept of a micro inverter is to pair an inverter with every panel, thereby, creating a self-contained single-panel solar system. Regardless of the number of panels, each will produce power.

If you intend to start with a small system and be able to expand over time, you may want to opt for this type of inverter. If you also want to independently monitor each panel, this is a great option.

Micro inverters make it easy to build your solar system at your own pace, although they cost more than other options. If you are on a budget and would rather build a complete system from the start, you may want to consider the most cost-effective option.

Advantages of Micro Inverters:

  • Monitoring at the panel level
  • A malfunctioning panel will not have a huge impact on the entire array, thereby increasing availability as there is no single point of failure.
  • Lower DC voltage on this system increases safety
  • Easy to use different models of modules in one system, especially when repairing or updating a system.

Disadvantages of Micro Inverters:

  • Higher costs
  • Complex installation
  • May have issues in extreme heat situations
  • The increased cost of maintenance due to the multiple units in an array

String Inverters

This inverter is commonly used in household and commercial solar systems.

A string inverter is a large box that is mostly found some distance away from the solar array, and the number of these inverters present depends on the size of the installation.

It is a single unit hooked into a string of solar panels. They are the least expensive option and do quite well under appropriate conditions.

Optimizers can also be paired with string inverters; this will help in solving shade problems. Adding optimizers to the panels is easy and effective when compared to replacing your whole inverter.

Advantages of String Inverters

  • High efficiency 
  • Low cost
  • Remote system monitoring
  • High design flexibility

Disadvantages of String Inverters

  • High voltage levels present a potential safety hazard
  • No monitoring at the panel level
  • Single point of failure. The entire solar system goes down if a string inverter goes out.
  • Cannot be used for roof-mounted systems unless paired with a panel-level rapid shutdown device.

Central Inverters

These are used for large arrays installed on buildings, industrial facilities, and field installations. Basically, they are very large string inverters and are never used for residential applications.

They usually look like large metal plates, dealing with up to 500 kilowatts of power.

Advantages of Central Inverters

  • High efficiency 
  • The comparative ease of installation

Disadvantages of Central Inverters

  • Size
  • Noise

Other types of grid-tie solar inverters are hybrids, battery inverters, and power-optimized inverters.

Hybrid inverters: these are also known as battery-based inverters that combine the grid-tie inverter technology with a battery inverter. Hybrid inverters convert direct current into alternating current for both solar panels and battery storage.

With hybrid inverters, a separate battery inverter is not a necessity for backup and even if the grid is down, you can rest assured knowing you will have backup power.

If you are looking for maximum design flexibility, increased monitoring capabilities, and lower maintenance, a hybrid inverter is your best bet.

Battery inverters: These are the best options for people who already have an inverter installed, but would like added energy storage without having to replace their solar systems with a hybrid inverter.

These inverters convert the stored power in the battery into usable alternating current (AC) and deliver the generated power via PV modules.

Power-optimized: They are also called PV inverters. Although more efficient, they are more expensive compared to string inverters.

These inverters are better suited for complex solar systems like those whose panels need to point in different directions. PV inverters are found at the back of each solar panel, just like micro inverters.

However, they do not convert the direct current (DC) electricity to alternating current (AC) electricity at the panel level. Instead, they optimize the direct current electricity before sending it to the central inverter.

Thus, the power output is improved, and there is a boost in the overall efficiency of the solar system.

Let us now look at some factors to consider when choosing a solar grid-tie inverter. These factors will serve as practical guides in helping you make an informed choice.

Factors to Consider when Choosing a Solar Grid-Tie Inverter

Having looked at the types of grid-tie inverters for solar systems there are, considering these factors will help you choose a product that will best serve your purpose. The following are the factors or things you want to look out for when choosing a solar grid-tie inverter:


The cost of an inverter depends on its type. The cost of micro inverters is commonly higher than that of string inverters. 

Power optimizers are usually less expensive compared to micro inverters, and you don’t necessarily need to attach an optimizer to each panel. You may only attach optimizers to panels that require optimization.

The main point remains that whatever inverter you choose to get depends on how much you are willing to spend on an inverter that fits your needs and budget. Just bear in mind that some installations are more expensive than others.


This deals with how efficiently a solar inverter converts direct current (DC) into usable alternating current (AC) for household use or a power grid. This isn’t much of an issue, as modern inverters are highly efficient.

The only situations where you might want to check for efficiency, are in cases where you are comparing significant differences between two inverters that are quite similar.


Most grid-tie inverters are weatherproof, but some are not, thereby requiring extra measures for weather protection. They may need special housing provisions for this.

Even if an inverter is weatherproof, it must be placed under a shade, as extreme heat and direct sunlight can reduce performance and durability. This is necessary as most inverters are located on external walls.


You can think of a solar inverter as a long-term investment, which is why it is essential that you check for and compare inverters based on their performance and durability.

I have already established the fact that some inverters are not suited for extreme weather conditions, which may lead to performance issues. Thus, it is important to go for an option that is resilient against these extreme conditions.

Identifying your Needs

Before purchasing a solar inverter, you need to identify your energy needs. This will help you choose a type of inverter that can generate as much energy as you need.

It is advisable to purchase an inverter that has the capacity to go beyond your energy needs, as there can be some energy loss in the system.


If you already have a brand in mind, you should carry out detailed research on it. Look out for opinions and reviews about the brand and its products.

This will greatly affect the decision you make in the end. Remember to go for a brand offering competitive prices and a warranty.


It is also important to take note of the physical dimensions of the inverter you are choosing. While micro-inverters are often sized like a normal paperback book, string inverters range in size between a big briefcase and a small suitcase.

Inverters are usually mounted in close proximity to the electric meters. Hence, with the physical dimension in mind, you would be able to consider how the inverter will look, mounted, and how close it can be placed to the meter.


This is another important factor to note, as the capacity of the solar inverter you need, is very much on your solar system. The inverter’s capacity deals with how much-generated power the inverter can handle.

The optimal choice here is to get the maximum number of solar panels and an inverter that is able to manage the power output of your solar system.


You need to consider this factor too if you plan to add panels to your existing solar system later. The best option is a multi-string inverter with MPPT trackers. 

With a multi-MPPT inverter, there is no need to worry about finding the same panel model as the ones already installed.


If the inverter you opt for has a display panel, you will be able to see how much power is being generated at the moment, for that day, and even during the entire lifetime of the inverter. It can show a lot of data.

The display light also indicates if the inverter is on. It can show you whether your inverter is running smoothly without any faults.

Remote Monitoring System

Some inverters come with a feature that allows remote monitoring. It can either be done using your smartphone or computer.

Choosing an inverter with this feature can be very convenient for you, especially if you don’t always want to walk to the inverter or meter to check on how it’s running.

However, most people completely forget about this feature, sometimes for months. If this is you, then, there is no need to overpay for an inverter with this feature when you are unsure you’re going to use it.

Power Outages

Most solar power systems turn off when there is a power outage. If you don’t want this to happen, then you may want to choose an inverter that allows the power to keep running, despite a power outage.

Inverters like this can be an expensive option. You will need a large solar system and a battery to keep the power running during several hours of a power outage.

Leaving only a few of the most important appliances running may, however, help in cutting down costs. Notwithstanding, the process would require additional electrical work, which will eventually lead to more expenses.

The Best Solar Grid-Tie Inverter: Pros and Cons


This is a brief rundown of the upsides of solar grid-tie inverters:

  • Lowest Cost: This inverter doesn’t require a solar battery which is a good thing as solar batteries are quite expensive. Also, grid-tie inverters need less installation equipment and there’s less work for the installers, thereby lowering the cost of labor.
  • More reliable than other PV options: grid-tie inverter has the fewest points of potential failure as it requires the least equipment.


The only notable downside of a solar grid-tie inverter is:

  • No power during grid outages: because they do not have battery storage, grid-tie inverters do not provide backup power.
