Datasheet

(1) The IQ8H-208 variant will be operating in grid-tied mode only at 208V AC. (2) No enforced DC/AC ratio. See
the compatibility calculator at https://link.enphase.com/module-compatibility (3) Maximum continuous input
DC current is 10.6A (4) Nominal voltage range can be extended beyond nominal if required by the utility. (5)Limits
may vary. Refer to local requirements to dene the number of microinverters per branch in your area.
