How long do solar inverters last?

Solar inverters play a crucial role in a solar energy system, but their lifespan is generally shorter than that of solar tiles, meaning an inverter will probably need to be replaced after five to 15 years, depending on its type and quality.

Extending the lifespan of a solar inverter

While solar tiles can last 25 years or more, solar inverters have a shorter lifespan due to several factors, including:

Wear and tear on electrical components

Environmental factors such as heat, humidity and dust

Electrical surges causing degradation

Thermal stress caused by heat generated during regular operation

To extend the life of a solar inverter, ensure it is installed in a suitable location – preferably in a well-ventilated area protected from harsh weather and dust.
Regular maintenance and monitoring are also critical. Periodic inspections can catch issues before they escalate and provide an opportunity to clear away any dust or debris. The inverter’s built-in monitoring system can help users track performance and provide early warnings of potential problems.

Signs that an inverter may need maintenance or replacement include:

Error codes or fault indicators

Decreased energy production

Frequent shutdowns

Overheating

Physical damage

Noisy operation

Inconsistent performance

Opting for high-quality products, such as Marley’s Clearline string inverter and the ES G2 hybrid inverter, is another way to ensure a solar inverter lasts as long as possible.
