FAQ: Your Questions Answered

What's the typical lifespan of industrial inverters?

Properly maintained units last 10-15 years, though IGBT modules usually need replacement after 7-8 years.

How do I size an inverter for solar installations?

Use this formula: Inverter Rating (kW) = Total Panel Capacity × 1.1 (safety factor). Always consult regional grid codes.
