Why should I purchase my Solar Inverter Replacement through ESE Group?

Many households throughout the UK have decided to invest in a solar PV system in order to help them save money and reduce their energy bills. However, in order to ensure that you are getting the maximum amount of energy generation out of your solar system, you must ensure that each component is working correctly.

Each element of your solar system, including your solar battery, inverter, and panels, will all have different predicted lifespans. While all solar system manufacturers will outline each lifespan in the manual for each component, you will have to purchase at least one new inverter and battery during the lifespan of your solar panels.

ESE can help you there.

What Is A Solar Inverter?

If you are considering purchasing, or already own, a solar panel system then a solar power inverter is an integral piece of equipment that you will require. Solar panels work by capturing sunlight that can be converted into solar power which, in turn, can be used to power your household appliances and devices.

However, solar panels do not do this on their own. In order to utilise the solar power that your panels create, you must attach a solar inverter to your PV array via wires. A solar inverter will work to convert the direct current (DC) that your panels create into alternating current (AC). DC is not compatible with your standard household appliances and devices, whereas AC is.

If you don’t have a solar inverter attached to your solar panel system, then the solar power that the system creates is rather useless.

Types Of Solar Inverter

In order to fully utilise your solar system unit, you will need to purchase a solar panel inverter to convert solar power into a usable current. Depending on your budget, needs, and the solar system that your household requires, there are a variety of different types of solar inverters available on the market. The most commonly used are micro inverters, string inverters, and power optimisers.

String Inverters

The oldest form of solar inverter is a string inverter. This type of inverter works by having each solar panel connected to a ‘string’. Then each string is attached to a singular inverter.

While this is a tried and tested method, sadly if one solar panel were to suffer performance related issues, then all your solar panels will be negatively impacted. Such performance issues could relate to damage or one panel being placed in a shaded area.

Micro Inverters

In order to avoid the primary drawback of string inverters, micro inverters were created. Instead of attaching all solar panels to one solar inverter, micro inverters are installed on each individual solar panel. 

Opting for micro inverters over a string inverter means that if one panel is damaged or in the shade, the rest of the solar array will not be impacted. However, the main drawbacks of this technology is that it is relatively new and more expensive than its older counterpart.

Power Optimisers

If you are looking for a cheaper version of a micro inverter, then you may wish to purchase a power optimiser. Like a micro inverter, they are installed on each solar panel.

However, the generated solar power is not converted on the roof, with the current sent to a singular inverter using the ‘string’ method. This presents customers with a cheaper alternative to micro inverters, but also maintains the benefits of not attaching each solar panel to a solo inverter.

Dual MPPT Inverters

Another important term you will need to become familiar with when it comes to solar inverters is dual MPPT (maximum power point tracking) inverter. By having a dual MPPT, you will be able to maximise the power output from two separate solar arrays.

Opting for a dual MPPT over the singular version can provide you with a host of benefits, including:

  • Higher efficiency levels.
  • Greater power output.
  • Having an improved, and more flexible, design.

How Will I Know If Solar Inverter Replacements Are Needed?

While purchasing your first solar PV inverter is considered a hefty investment, sadly the component will not last the entire lifespan of your solar panel system. Inverter replacements are incredibly common, and should be an expense that you are prepared to make before initially purchasing your solar system.

If you are worried about whether it is time to purchase a replacement inverter, we have listed the four key ways you can determine whether your solar PV inverter needs replacing below.

Age Of Your Solar Inverter

Most inverters will come with a predicted lifespan when you make your purchase. Typically, inverters will last between 10 to 12 years, meaning that you will have to purchase multiple inverters across the lifespan of your solar panel system.

However, you should always check the inverter manual of your existing inverter to ensure that it follows the typical lifecycle of other inverters on the market.

Your Energy Bills Are On The Rise

If you see that your energy bills are on the rise, this is yet another key sign that perhaps your solar inverter isn’t working as efficiently as possible. This could be as a result of a fault on your inverter that could easily be fixed, or it may simply be time to purchase a whole new inverter.

Your Solar Inverter Generation Meter Is Decreasing

Similar to a potential increase in your energy bills, if you are seeing a decrease in the energy output provided by your solar PV system, then it may be time to purchase a new inverter.

Throughout the time period that you have owned and used your existing inverter, you will know how much energy you can expect it to convert during the year. If there is an unexplained dip, then there could be an issue with your inverter.

Your Inverter Screen Is Displaying Warning Lights

One of the main reasons you may question whether it is time to purchase a new inverter is if your inverter display is showing a warning light. This light may be flashing or constant, either way it is a key indicator that something may be wrong with your inverter.

Additionally, your inverter display could show a variety of error codes or error messages. Whether it is a light or some kind of message you’re seeing, you should get in touch with the original installer of your inverter as soon as possible.

Factors you need to consider when purchasing a new Solar Inverter

When shopping around for your perfect solar inverter replacement, you should take into account these four key factors:

  • Efficiency Level: Researching how efficient each inverter model is will provide you with a key indicator regarding the quality of the product.
  • Warranty Period: Typically, a solar inverter will come with a 5 year warranty. However, each different brand may offer varying warranty lengths so be sure to shop around.
  • Inverter Features: Inverter features like free monitoring, whether it is Wi-Fi enabled, or if it offers wireless connection are just some of the features you may wish to look out for when researching the inverters available on the market.
  • Customer Support: Once you have purchased your inverter, you will have to maintain it for around 10 to 12 years. Ensuring that the company you purchase the inverter from offers you support post-purchase will be key if you were to experience any issues in the future.


Of course, you will also wish to look for the best prices that are available on the market before purchasing an inverter. ESE Group’s solar experts will be able to find you the perfect inverter in your budget when you work with us.

Solar Inverter Replacement FAQs

Some of the most common questions about solar inverter replacements are answered for you here…

If you are opting to have your solar inverter replacement completed by ESE Group, or any other qualified technician, then replacing your solar inverter will typically take between 1 to 2 hours. However, it should be noted that this predicted time frame relates to installation jobs where the installers don’t suffer any unforeseen issues.

As we have previously mentioned, solar panels will have a longer predicted lifespan compared to various other components included in your solar PV system. Three of the most important predicted lifespans that you will need to remember regarding your solar system are:

  • Solar Battery: 5 to 15 years.
  • Solar Inverter: 10 to 12 years.
  • Solar Panels: 25 to 30 years.
