No, pairing a high-wattage module with the M215 microinverter will not itself void the inverter’s warranty.
The Enphase M215 warranty does not cover damage to the microinverter when used under conditions for which the product was not designed.
While the module wattage in question is outside the range listed in the M215 datasheet, this is only a recommended value, and not a design specification.
However, exceeding the maximum voltage or current inputs can damage the microinverter, and will void the product warranty.
To check a module / microinverter pairing, the Enphase online Module Compatibility Calculator should be used to verify compatibility.
