How Long Is The Warranty On An Inverter?

To safeguard your investment in renewable energy, it is essential to have a solid understanding of the warranty coverage that your inverter provides.

Having a thorough understanding of the inverter’s warranty will provide you with both peace of mind and financial security, regardless of whether you have recently installed a solar power system or are contemplating incorporating one into your house.

This article delves into the particulars of inverter warranties, discussing their term, coverage, and the characteristics that you should look for when choosing the guarantee that is most suitable for your requirements.

How Long Is The Warranty On An Inverter?

The length of time that an inverter’s warranty lasts is usually manufacturer and model-dependent. The guarantees offered by respectable manufacturers, however, typically span anywhere from five to twenty-five years. Warranties on entry-level inverters tend to be shorter compared to those on premium or high-end devices.

To know what is covered and for how long under the manufacturer’s warranty, it’s important to read the terms and conditions thoroughly. For an extra cost, you can get an extended warranty from select manufacturers, which gives you even more assurance that your investment will last.

Here are some examples of inverter warranties from prominent manufacturers:

  • Enphase Energy: Enphase offers a standard warranty of 10 years for its microinverters. Additionally, they provide an option to purchase an extended warranty for up to 25 years.
  • SolarEdge: SolarEdge typically provides a standard warranty of 12 years for its inverters. Similar to Enphase, they offer an extended warranty option, allowing customers to extend coverage up to 25 years.
  • Fronius: Fronius inverters often come with a standard warranty of 5 to 7 years. However, they offer various warranty extensions, including options for up to 20 years of coverage.
  • SMA Solar Technology: SMA offers warranties ranging from 5 to 25 years, depending on the specific inverter model. They also provide extended warranty options for further coverage beyond the standard terms.
  • ABB (formerly ABB Power-One): ABB typically provides warranties ranging from 5 to 10 years for its inverters. Extended warranty options may also be available for certain models.

These examples illustrate the range of warranty durations offered by different manufacturers and the availability of extended warranty options for additional peace of mind.

When selecting an inverter, it’s essential to consider not only the upfront cost but also the warranty coverage and the reputation of the manufacturer for reliability and customer support.

What Is A Standard Inverter Warranty?

A standard inverter warranty typically refers to the baseline warranty coverage provided by the manufacturer for their inverters without any additional cost. The duration and terms of a standard warranty can vary significantly among manufacturers and even different models within the same manufacturer’s product line.

Here are some common features of a standard inverter warranty:

  • Duration: Standard warranties for inverters often range from 5 to 12 years, though some manufacturers may offer longer or shorter periods. The duration usually depends on factors such as the quality of the product and the manufacturer’s confidence in its longevity.
  • Coverage: Standard warranties typically cover manufacturing defects and failures that occur under normal operating conditions. This may include repairs or replacements of faulty components, labour costs, and sometimes shipping expenses.
  • Exclusions: Certain conditions or situations may be excluded from standard warranty coverage. For example, damage caused by improper installation, misuse, neglect, or acts of nature (such as lightning strikes or floods) may not be covered under the standard warranty.
  • Transferability: Some standard warranties are transferable, meaning they can be transferred to subsequent owners if the property where the inverter is installed is sold. This can add value to the property and assure new owners.
  • Registration: Manufacturers may require product registration to activate the standard warranty. Failure to register the product within a specified timeframe after purchase could result in the warranty being voided or shortened.

It’s essential for consumers to carefully review the terms and conditions of the standard warranty provided by the manufacturer before purchasing an inverter.

Understanding what is covered, the duration of coverage, any exclusions, and any requirements for activation or registration can help consumers make informed decisions and ensure proper protection for their investment.

What Is The Main Cause Of Inverter Failure?

The main cause of inverter failure can vary depending on several factors, including the quality of the inverter, the environment in which it operates, and how well it is maintained. However, some common reasons for inverter failure include:

  • Component Degradation: Over time, electronic components within the inverter can degrade due to factors such as heat, moisture, and electrical stress. This degradation can lead to malfunctions or complete failure of the inverter.
  • Overheating: Inverters generate heat during operation, and if they are not adequately cooled or ventilated, this heat can build up and cause damage to internal components. Overheating can occur due to factors such as high ambient temperatures, inadequate airflow, or excessive power loads.
  • Electrical Surges: Power surges or spikes in the electrical grid can damage sensitive components within the inverter, leading to failure. Lightning strikes, grid disturbances, or switching events within the electrical system can all cause electrical surges that may affect the inverter.
  • Improper Installation: Incorrect installation of the inverter, including improper wiring, grounding, or mounting, can lead to operational issues or damage over time. It’s essential to follow manufacturer guidelines and industry best practices when installing an inverter to minimize the risk of failure.
  • Manufacturing Defects: In rare cases, manufacturing defects or quality control issues within the inverter itself can lead to premature failure. These defects may manifest shortly after installation or become apparent over time as the inverter ages.
  • Environmental Factors: Exposure to harsh environmental conditions such as extreme temperatures, humidity, dust, or corrosive elements can accelerate the deterioration of inverter components and contribute to failure.
  • Age: Like any electronic device, inverters have a finite lifespan, and as they age, the likelihood of failure increases. Regular maintenance and periodic inspections can help identify potential issues early and extend the lifespan of the inverter.

Proper installation, regular maintenance, and choosing a high-quality inverter from a reputable manufacturer can help minimize the risk of failure and ensure reliable operation over the lifespan of the system.


However, even though inverters are vital components of solar power systems and other installations that utilise renewable energy, they are not immune to malfunction. One of the most important things you can do to ensure the dependability and durability of your system is to gain an understanding of the probable causes of inverter failure.

Component deterioration, overheating, electrical surges, incorrect installation, manufacturing faults, and environmental variables are some of the most common reasons for inverter failure.

To reduce the likelihood of an inverter failing, it is vital to make an investment in a high-quality inverter that is manufactured by a reputable company, adhere to the appropriate installation procedures, and undertake routine maintenance to guarantee the best possible performance.

In addition, homes and business owners should be diligent in checking their inverters for symptoms of malfunction and swiftly addressing any issues that arise to prevent further harm.

By taking these preventative precautions and remaining knowledgeable about the coverage and support alternatives available for inverter warranties, consumers can safeguard their investment in renewable energy and continue to take pleasure in the generation of electricity that is dependable and environmentally friendly for many years to come.
