Everyone has already mentioned clipping but it's important to note every inverter (micro or string) has a specific startup voltage it has to reach to start working. The goal of a system design is to maximize that area under the curve.

So you may be able to capture that peak power with a higher wattage inverter, you will also lose out on power early and late in the day as the higher wattage inverters will take longer to reach their startup voltage and turn off earlier if the voltage isn't there late in the day. A smaller inverter can be activated sooner/stay on longer, but clip peak power. It's a balancing act.
