Enphase M250 Microinverter Features

The fourth-generation Enphase Microinverter, the M250, maximizes the energy production of 60-cell solar modules up to 300W and includes Integrated (DC Isolated) Ground.

The Enphase® M250 Microinverter is a grid-tie inverter that delivers increased energy harvest and reduces design and installation complexity with its all-AC approach. With the M250, the DC circuit is isolated and insulated from ground, so no Ground Electrode Conductor (GEC) is required for the microinverter. Not requiring a GEC further simplifies installation, enhances safety, and saves on labor and materials costs.

The Enphase M250 integrates seamlessly with the Engage® Cable, the Envoy® Communications Gateway™, and Enlighten®, Enphase’s monitoring and analysis software.

We asked for reviews from our staff: "We have found that do-it-yourself solar installers are surprised by how easy these are to install. Then they find the system performance is top-notch...especially on partially shaded roofs!"
