FAQ

What is the lifespan of split phase off grid inverter?

The lifespan of off grid split phase inverter typically ranges between 10 to 15 years, though this can vary depending on factors such as quality, usage, and maintenance practices. A well-maintained inverter from a reputable manufacturer can last longer.

Several factors influence the lifespan:

  • Environment. The operating environment plays a critical role. Inverters exposed to extreme temperatures, high humidity, or dust are more likely to experience wear and tear faster. Proper ventilation and cooling can mitigate some of these effects.
  • Load and Usage. Inverters that are consistently running close to their rated capacity may wear out more quickly. Overloading or running an inverter for extended periods without sufficient rest can reduce its operational life.
  • Maintenance. Regular cleaning, inspection of connections, and ensuring that the inverter is operating within specified voltage and current limits can prolong its lifespan. Dust buildup, especially on cooling fans, can increase the likelihood of overheating.
  • Power Surges and Faults. Off grid solar inverters can be more vulnerable to power surges or electrical faults, especially in rural areas where grid power is unstable. Using proper surge protection can help extend life.
