Can you use solar panels larger than recommended?

Long story made short, I have ~10 year old Enphase M210 inverters. Enphase recommends an input of 31-50 volt and 240 watt solar panel. However, I cannot find any new panels that are ~240 watts in anything but 12 volts. I did find a good deal locally on some 305 watt panels. I know that it's not optimal efficiency, but would the 305 watt panel damage the inverter short or long term?

A quick read of the manual does not list a maximum input wattage. And MPPT controllers/inverters should safely limit output current/power to the device's capability.
Using nominal math:
- 36 volts * 10 amps Imp * 0.8 Imp to Isc conversion (estimate) = 288 Watt maximum 72 cell (Vmp~36 volts)
- 42 volts * 10 amps Imp * 0.8 Imp to Isc conversion (estimate) = 336 Watt maximum 84 cell (Vmp~42 volts)
The above are just guesses... Usually "damage" occurs when maximum input voltage is exceeded (hard limit). Exceeding input current should be less of an issue (micro inverter will simply draw less current than panel could supply).Depending on Enphase specifications... They could be Isc=10 amps as their limit, or Imp=10 amps as the input limit (or they could be squishy and not tell you which limit is the 10 Amps).
Again, I do not work for Enphase or UL/etc... I am just reading the specifications and trying to determine what would work for you.
This is your decision (hopefully with input as needed from Enphase).

I would not do it... Instead, just look for a 240 Watt panel--used or new (or, for example, 2x ~120 Watt 36 cell panels in series).
Not sure what else you can do other than buy a different/newer model of micro-inverter (and the issue of how to remote monitor--compatible with what you have or not)..

Of course it's safest to use the lower of this and their verbal statements.
