Microinverter A panel-level inverter that converts DC to AC right at each solar panel

← All Glossary Terms Definition
A microinverter is a small inverter mounted at each individual solar panel that converts the panel's DC output to usable AC electricity right at the panel. Unlike a centralized string inverter, microinverters operate each panel independently, which improves performance under partial shade and lets one underperforming panel avoid dragging down the rest of the array. They also enable per-panel monitoring, so you can see how each module is producing and spot problems faster. The trade-off is cost: microinverters typically come at a higher cost than a string inverter, since you're buying one unit per panel instead of a single central device. Whether the extra spend is worth it usually depends on your roof's shading, layout, and how much you value granular monitoring. Pricing and warranty terms vary by manufacturer and installer.

Module-level inverter Panel-level inverter Microinverter system MLPE (module-level power electronics)
Used in Context
  1. Because oak trees shade part of the roof each afternoon, the installer recommended microinverters so the shaded panels wouldn't reduce the whole array's output.
  2. When you compare solar quotes from Dreamy Leads, ask each company whether they're proposing microinverters or a string inverter and how that affects price.
  3. After installation, the homeowner used the microinverter app to confirm every panel was producing as expected before signing off on the project.

Frequently Asked Questions

Are microinverters better than string inverters?

It depends on your situation. Microinverters handle partial shade better and offer per-panel monitoring, but they usually cost more than a string inverter. If your roof is largely shade-free and uniform, a string inverter may be enough. Heavy shading or complex layouts often favor microinverters.

Do microinverters cost more than a string inverter?

Yes, microinverters typically cost more than a string inverter because you install one unit per panel rather than a single central device. The extra cost can be worthwhile if you have shading or want detailed per-panel monitoring. Actual pricing varies by manufacturer, installer, and system size.

What does per-panel monitoring actually do for me?

Per-panel monitoring lets you see how each individual panel is producing instead of just the whole system. This makes it easier to spot a faulty or underperforming panel quickly so it can be serviced. With a string inverter, you generally only see the array's combined output.
