On average, an inverter lasts between 5 and 15 years, depending on factors such as quality, usage and maintenance. Inverters from reputable manufacturers, with high build quality and proper installation, tend to last closer to the higher end of this range. Regular maintenance and ensuring the inverter operates within its specified limits can also contribute to its longevity.
The inverter that lasts the longest is usually from a reputable manufacturer known for its durable, high-quality products.
Brands such as SMA, Fronius and Enphase are known for producing inverters with extended lifespans, often backed by warranties of 10 years or more. Choosing a UPS with a solid track record and good warranty coverage can provide greater assurance of long-term reliability.
Inverters can break down quickly for several reasons, including poor quality components, poor installation, or operating conditions that exceed their specifications. Common problems include overheating, electrical faults, and wear and tear from frequent use.
Ensuring the inverter is properly sized for the system, installed correctly, and maintained regularly can help alleviate these problems and extend its lifespan.
How often an inverter fails can vary depending on factors such as its quality, usage, and environmental conditions. Although high-quality inverters generally experience fewer problems, some may experience problems during the first few years of operation due to manufacturing defects or improper handling.
Regular maintenance and following the manufacturer’s guidelines can help reduce the risk of inverter failure.
Rectifiers, which are components used to convert alternating current to direct current, typically last between 10 and 20 years, depending on their quality and conditions of use. High-quality rectifiers used in well-maintained systems can approach the upper end of this range. Factors such as operational stress, heat and electrical load can affect their lifespan. It is therefore crucial to ensure that they perform within their rated specifications for longevity.
