Enphase M250 Micro-Inverter

Enphase M250

The Enphase M250 Micro-Inverter is designed to optimize the output of today’s higher power panels — with more power, higher efficiency and a smaller footprint.

The Enphase M250 integrates multiple components and functions in a single package, including AC cabling and equipment ground, resulting in significantly lower cost and faster installation. New capabilities include:

  • 208V/240V autosensing
  • Compatibility with 60 cell modules up to 280W
  • Peak efficiency of 98.7 percent
  • Maximum output power of 240 watts AC

Backed by the company’s signature 25-year warranty, the Enphase M250 Micro-Inverter is based on highly reliable architectural design with no electrolytic capacitors and an extremely efficient thermal design.

The Enphase M250 is CSA certified to UL1741   Australia – Regulatory Compliance Mark (RCM)  Safety Certificate of Suitability CS9905NAS/NZS 3100, AS 60529, AS 4777.2, AS 4777.3

Benefits for you:


  • Roof-ready AC modules are up to twice as fast to install as DC modules.
  • System design becomes easier with no string sizing or DC bus cables.
  • Additional AC modules are easy to add because each module operates independently.
  • No GEC needed for microinverter
  • No DC design or string calculation required
  • Easy installation with Engage Cable

Better Reliability

  • Only Enphase M250 offers an integrated microinverter backed by the same 25-year guarantee as a solar module.
  • Rigorous testing and qualification ensures performance and reliability well beyond regulatory standards.
  • Constant on-site monitoring identifies performance issues quickly, minimizing any system downtime.

Greater Energy Harvest

  • Maximum Power Point Tracking (MPPT) at the module level means each AC module produces its maximum power.
  • AC module system produce up to 25 percent more energy, even in shady conditions.
  • Sites previously disqualified due to shade or roof orientation are now good candidates for solar.

Increased Safety

  • No exposed DC wiring on the roof or in the building, decreasing the risk of shock hazard or arc fire.
  • In the event of a fire, rescue workers can shut off all live electricity, not just the central inverter.
