The Enphase M215 and M250 are module-level microinverters made by Enphase, built in M250-60, M250-72 and two M215-60 versions. The M250 is rated at 240 W continuous AC output, with 250 W peak, on either 240 V split-phase or 208 V three-phase service at 60 Hz. An AC branch circuit can hold up to 16 M250 units on 240 V or 24 on 208 V, and up to 17 M215 units on 240 V or 25 on 208 V. These units talk over power line communication, and their enclosures are rated NEMA 6. The IQ 7-based M215 and M250 expansion models are Class II double-insulated with ground fault protection, so they need no GEC, EGC or neutral conductor. A solid red status LED means a DC Resistance Low - Power Off fault on the M250 and M215-60-2LL-S22-IG, or a GFI Tripped fault on the M215-60-2LL-S22. These faults stay latched until an Envoy sends a clear message, and the clear will not hold while the cause, such as damaged insulation, wiring or moisture, is still present.
