The APsystems YC600 microinverter offers a wider MPPT voltage range, higher input power than the IQ7, a lower startup voltage, and a higher output power than two IQ7 or even two IQ7+.

The Enphase IQ7 microinverter offers a minimally higher efficiency and a slightly reduced form factor.

The Enphase IQ7+ microinverter allows the highest input power, a higher maximum input DC voltage, and a slightly reduced form factor.
