These are new M250-72 Enphase inverters. These inverters will work with either 60 or 72 cell solar panels. These are the New IG style inverter with integrated ground (requires no additional grounding wire) and are equipped. With MC4 solar connectors. These can be used along with the older versions of M215 inverters but do not need a separate ground connection. These inverters attach to the standard Enphase Engage cabling system (the same cable used with the M215). The versatile Enphase M250 Microinverter performs in both residential and commercial solar PV installations and is compatible with both 60-cell and 72-cell modules. With its all-AC approach and integrated grounding, the M250 delivers increased energy harvest and reduces design and installation complexity. The Enphase M250 Microinverter integrates seamlessly with the Enphase Engage Cable, the Enphase Envoy communications gateway, and Enphase Enlighten monitoring and analysis software. The M250-72 micro-inverter can be used with 60 cell panels or 72 cell panels and has a MPPT Voltage range of 27-48 VDC (see recommended input power below). The M250 auto-detects if the grid is 240VAC (211-264VAC) or 208VAC (183-229VAC) 3-phase. The M250 has MC4 connectors that connect to your MC4 solar panel connectors. Each 240VAC branch circuit can have 16 micro-inverters maximum (16 modules). Each 208VAC branch circuit can have 24 micro-inverters maximum (24 modules). You may have multiple branch circuits. The Enphase Engage AC cable system is used with cable drops to quickly connect each inverter along the AC trunk. Each branch circuit requires a 20 amp breaker. Branch circuits can be combined together with a load center. One Enphase end termination cap is needed at the end of the Engage AC branch circuit cabling. The Enphase Energy Microinverter System improves energy harvest, increases reliability, and dramatically simplifies design, installation and management of solar power systems. Works with the Envoy Communications Gateway monitoring system just like the M215. Resilient to dust, debris, and shading. Performance monitoring per module. System availability greater than 99.8%. No single point of system failure. Quick & simple design, installation and management. Works with 60 Cell or 72 Cell Modules (see recommended power below). The M250 has (1) set of DC inputs.

Compliance UL1741/IEEE1547, FCC Part 15 Class B, CAN/CSA-C22.2 NO. 0.4-04, and 107.1-01. Integrated ground The DC circuit meets the requirements for ungrounded PV arrays in. Equipment ground is provided in the Engage Cable. Additional GEC or ground is required. Ground fault protection (GFP) is. Integrated into the microinverter. Frequency ranges can be extended beyond nominal if required by the utility. This is a BRAND NEW INVERTER from a case of brand new inverters. It is not used and has not been previously installed.
