Enphase C250 Microinverter for Commercial Solar PV Systems

The Enphase® C250 Microinverter delivers superior commercial project economics by increasing overall energy harvest and system availability along with substantial reductions in material and labor costs. Used with a transformer, the C250 Microinverter System meets the needs of medium and large commercial installations where power distribution is 277 V/480 WYE or medium voltage (MV). With support for both 60- and 72-cell modules, the system provides a flexible, operationally efficient, and cost effective solution across all commercial project segments.

The Enphase C250 integrates seamlessly with the Engage® Cable, the Envoy-C® Communications Gateway and Enlighten,® Enphase’s monitoring and analysis software.

Maximizes energy production

Enphase C250 Microinverter Commercial Quality
Enphase Microinverter technology has undergone over 1 million hours of testing. Millions of Enphase Microinverters are currently in use worldwide.
  • Designed for higher-power, 60-cell & 72-cell solar PV modules
  • No single point of system failure
  • Minimizes impact of shading, dust, and debris

Simple and Reliable

  • No DC design or string calculation required
  • Easy installaion with Engage Cable
  • More than 1 million hours of testing
  • Millions of units shipped and in use
  • All units performance tested prior to shipment
  • Industry-leading warranty, up to 25 years
  • No grounding electrode conductor (GEC) needed for microinverter

Superior economics - bottom line.

Enphase microinverters bring you a lower LCOE and a higher IRR. Unlike conventional inverters, microinverters operate independently, so one struggling module won’t drag the whole system down. Combine higher production with lower O&M and BoS costs, and you get greater value.

Enphase C250 Compatibility

Compatible with most modern 60-cell and 72-cell PV modules. It is similar to the M250 but the C250 is designed for commercial 277 V/480 WYE or medium voltage (MV) 3-phase utility service.


Power line

Integrated ground

The DC circuit meets the requirements for ungrounded PV arrays in NEC 690.35. Equipment ground is provided in the Engage Cable. No additional GEC or ground is required.
