Best Microinverters Under $200

A low cost one panel unit for 400 to 450 W panels, with input current to spare and the same 25 year warranty as Enphase.

The Enphase choice for today’s 450 W and larger panels. It gets the most output per panel in the line at its lowest price per watt.

The best value in the Enphase line for 350 to 450 W panels. It takes more current than the IQ8M for less money.

A single panel inverter for big 500 W+ panels where shade or odd roof planes call for one inverter per panel. For a plain array, a Hoymiles four panel unit costs much less per watt.

The Enphase pick for 400 to 500 W panels, replacing the IQ8A with a higher input current at a lower price.

A good match for 350 to 450 W panels on an Enphase system. Check the IQ8MC price first, since it takes more current for less.

For big 72 cell panels on a 240 V Enphase system. The IQ8HC does the same job with more input current and usually costs less.

The common choice for 60 and 72 cell panels up to about 400 W on an Enphase system. For bigger modern panels, the IQ8HC or IQ8MC takes more current for less per watt.

For adding to or repairing an existing Enphase system with older 60 cell panels. On a new build with modern panels, an IQ8M or larger costs less per watt.

The two panel pick for big modern panels: the highest input current here and a low price per watt from retailers.

A cheap, efficient two panel unit for pairs of 350 to 450 W panels, with input current to spare.

A two panel unit for smaller 300 to 350 W panels. Pairs of modern 400 W+ panels lose output to clipping.

A two panel unit for smaller 300 to 350 W panels. Most buyers should get the DS3-L, which costs less.

The cheapest way per watt to run pairs of 300 W class panels, but confirm the warranty with the seller before buying.
