FAQ Section

How long do inverter components typically last?

Quality components can function 8-12 years with proper maintenance, though capacitors often need replacement after 6-8 years.

What's more important - MPPT efficiency or conversion rate?

Both parameters matter, but prioritize conversion efficiency (97%+) for grid-tied systems and MPPT performance (98%+) for variable shading conditions.
