Enphase Energy 250 Watt Micro Inverter w/Integrated Ground(H4)
Over a million hours of testing went into Enphase’s fourth generation microinverter, the M250 series. The M250 delivers increased energy harvest, and reduces design and installation complexity with its all-AC approach. The M250 has been optimized for higher power modules, its’ broader operating voltages maximizes energy production while minimizing the impacts of shading dust and debris.
With the M250, the DC circuit is isolated and insulated from ground, so no Ground Electrode Conductor (GEC) is required for the microinverter. This 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.

*About System Grounding:
Electrical code requires two types of grounding conductors: the Grounding Electrode Conductor (GEC), which is used between the grounding electrode and the point where a normally current carrying conductor is intentionally bonded to ground, and the Equipment Grounding Conductor (EGC), which grounds noncurrent carrying metal parts of the system, such as the racking and module frames. Because Enphase Microinverters with Integrated Ground have DC integrated ground, they do not require a GEC. However electrical code still requires that exposed metal in the array be grounded (NEC 690.43 and 250.136(A)). This requirement is met for the microinverter because the ground conductor internal to the Engage Cable acts as the EGC. It may be met for racking and modules with use of an EGC or WEEBs to provide bonding to this ground system.
The Enphase Microinverter system is the world’s most technologically advanced inverter system for use in utility-interactive applications. The three key elements of an Enphase Microinverter System are:
- the Enphase Microinverter
- the Enphase Envoy communications gateway
- the Enphase Enlighten™ web-based monitoring and analysis
This integrated system maximizes energy harvest, increases system reliability, and simplifies design, installation and management.
