Quick Summary
Microinverters are miniature inverters mounted underneath each individual solar panel. They perform DC-to-AC conversion right on the roof, isolating each panel so that shading or dirt on one module does not reduce the output of the rest.
Enphase is the global leader in microinverter technology. Their flagship IQ8 series supports panel-level rapid shutdown compliance and provides cell performance monitoring via smart phone apps.
Key Benefits of Microinverters
- Shading Isolation: Ideal for roofs with chimneys, tree branches, or dormer shading.
- Flexible Expansion: Add panels to your system easily later without replacing the inverter.
- Longevity: Matches the 25-year performance warranty of solar panels.
Frequently Asked Questions
Is it worth paying more for microinverters?
Yes, for complex roofs with multiple angles or partial shading. For simple, unshaded south-facing roofs, central string inverters may be more cost-effective.
