The M250 Photovoltaic Inverter is the 4th Generation micro-inverter released by Enphase Energy. It produces 250 Watts peak AC output power with MPPT to optimize efficiency in difficult solar conditions.

In the M250, the DC circuit is isolated and insulated from ground, so no External Ground Electrode Conductor (GEC) is required. The M250 is fully filled with Resin to protect the components from the weather constraints and to improve the thermal dissipation.

Based on a complete teardown analysis, the report provides an estimation of the production cost of the M250 inverter, and a comparison with previous report on M215.
